Configuration Common Linux: Difference between revisions

Revision as of 12:51, 26 April 2022

This page details a common configuration for Linux, independent of the underlying platform.

To Do

Basic configuration for standard installation
Move settings that can be recovered from HOME directory in separate section.

Base

On Debian, login as root and add default user (uid 1000) as root.

su -
USERNAME=$(awk -F: '/:1000:/ {print $1}' /etc/passwd)
gpasswd -a $USERNAME sudo

# Terminate all users process !!! this will FORCE LOGOUT !!!
# ... alternatively: su - $USERNAME to avoid logout
loginctl terminate-user $USERNAME

Install etckeeper (with git).

# ### etckeeper + git

sudo apt install git etckeeper terminator
sudo make -C /usr/share/doc/git/contrib/diff-highlight # Fix diff-highlight
sudo ln -sf /usr/share/doc/git/contrib/diff-highlight/diff-highlight /usr/local/bin/diff-highlight
git config --global user.email "user@server.com"       # Make sure this is defined for admin user + root
git config --global user.name "User Name"              # or release upgrade might fail in the future
sudo su -
git config --global user.email "$USER@$HOSTNAME"
git config --global user.name "root"
logout

sudo vi /etc/etckeeper/etckeeper.conf                  # Select git, AVOID_DAILY_AUTOCOMMITS, AVOID_COMMIT_BEFORE_INSTALL
sudo etckeeper init
sudo etckeeper commit "1st commit"
cd /etc
sudo vi .gitignore                                     # Ignore resolv.c*, cups/ppd, cups/printers.conf* (and cups/subscriptions.* before Ubuntu Precise)
sudo git rm --cached resolv.c*
sudo git rm --cached cups/subscriptions.*              # No longer needed on Ubuntu Precise and after
sudo etckeeper commit "ignore resolv.c*, cups/subscriptions.*"

Then we install ssh (incl. ssh server), vim + mc, and avahi (often preinstalled)

sudo apt install ssh vim mc                            # Debian 9+
sudo apt install ssh vim-gnome mc                      # Older
sudo apt install libnss-mdns avahi-daemon mdns-scan

From now, the configuration can continue either locally or remotely (using ssh).

We now install a few repositories, as required.

See also Ubuntu Tweak, XBMC, Gnome Terminator, Medibuntu (replaced by Videolan)

sudo vi /etc/apt/sources.list                          # Debian: enable 'main non-free contrib'
                                                       # Ubuntu: enable 'partner' and 'extra' (if available)
sudo add-apt-repository ppa:phoerious/keepassxc        # Ubuntu: keepassxc
# sudo add-apt-repository ppa:synapse-core/ppa         # Ubuntu <14.04 - Synapse
sudo add-apt-repository ppa:tualatrix/next             # Ubuntu: Ubuntu Tweak
sudo add-apt-repository ppa:team-xbmc/ppa              # Optional: XBMC

sudo etckeeper commit "Update repositories"
sudo apt update
sudo apt upgrade # This may upgrade firmware to non-free versions

hosts — Update /etc/hosts

sudo vi /etc/hosts                                                 # Add any relevant entries.
                                                                   # Make sure localhost has FQDN:
                                                                   #     127.0.1.1	myhost.domain.com
sudo etckeeper commit "update hosts file"

sudoers — Create new files in /etc/sudoers.d as required:

# envkeep
# http_proxy, https_proxy -- to keep proxy settings for apt-get etc
# GREP_OPTIONS            -- keep grep options
# DISPLAY, XAUTHORITY     -- avoid doing 'xhost local:root' before launching X pgm
# HOME                    -- e.g. to keep git aliases and settings when using etckeeper
# PASSWD                  -- e.g. to pass password via env. var to <code>mount.cifs</code>
echo "Defaults env_keep += \"http_proxy https_proxy GREP_OPTIONS DISPLAY XAUTHORITY HOME\"" | sudo tee /etc/sudoers.d/envkeep
# Truecrypt
echo "ALL ALL = NOPASSWD: /usr/bin/truecrypt" | sudo tee /etc/sudoers.d/truecrypt
# Privoxy - no longer needed with tun2socks-manager
#echo "ALL ALL = (ALL) NOPASSWD: /etc/privoxy/set-network-config" | sudo tee /etc/sudoers.d/privoxy
# rfkill - no more used
#echo "ALL ALL = NOPASSWD: /sbin/rfkill" | sudo tee /etc/sudoers.d/rfkill
sudo chmod o-r /etc/sudoers.d/*
sudo etckeeper commit "update sudoers.d files"

Restore home profile (from git)

# Restore my profile
mv home/.git .
rm -rf home
git reset --hard
git st
export PATH=$PATH:$HOME/bin
set-network.sh
~/setup.sh

Restore old keyboard dead keys behaviour by uninstalling im-config:

DOES NOT WORK - on Bullseye, still get the strange behaviour. Maybe due to Wayland?

# No more the issue on Bookworm (with pkg installed - so not root cause)
# sudo apt remove im-config       # DOES NOT WORK - To avoid ¨ / ^ displaying while composing, and other nasty side effects

Locale (at least since Debian 10 Buster)

ATTENTION Using the locale en_DK.UTF-8 break Wine Command Prompt (bad keyboard config).

To fix that, for instance for PlayOnLinux, edit file /usr/share/applications/PlayOnLinux.desktop

vi /usr/share/applications/PlayOnLinux.desktop

-Exec=playonlinux %F
+Exec=env LC_ALL=en_US.UTF-8 playonlinux %F

Edit /etc/locale.gen, and uncomment line en_DK.UTF-8 UTF-8, then update the locale

sudo vi /etc/locale.gen
# ...
sudo locale-gen

Edit /etc/default/locale, and add line LC_TIME="en_DK.UTF-8" [1], [2]

sudo vi /etc/default/locale
# ...

In Gnome, select en_DK.UTF-8 for format in Region and Language settings.

SSD Trim

If using an SSD, enable TRIM (but see WARNING HERE).

sudo systemctl enable fstrim.timer
sudo systemctl start fstrim.timer

Kernel update

Install latest kernel [3]

# Get Utopic kernel
sudo apt install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic
# Get Vivid kernel
# DO NOT UPDATE TO VIVID X.ORG - IT LEAKS LIKE HELL
# sudo apt install --install-recommends linux-generic-lts-vivid xserver-xorg-lts-vivid libgl1-mesa-glx-lts-vivid libegl1-mesa-drivers-lts-vivid
sudo apt install --install-recommends linux-generic-lts-vivid

Ufw

Keep UFW logs only in /var/log/ufw.log. Edit /etc/rsyslog.d/20-ufw.conf:

-#& stop
+& stop

Then

sudo service rsyslog restart

Install gufw

sudo apt install gufw

If necessary, restore old gufw profiles from /etc/gufw.

X11

Custom keyboard mapping be:

# From my profile
sudo cp ~/etc/be /usr/share/X11/xkb/symbols/be
sudo rm /var/lib/xkb/*.xkm
setxkbmap us
setxkbmap be

Use CapsLock as an extra Esc key (see X#Configuring_Layout_Options)

gsettings get org.gnome.desktop.input-sources xkb-options
gsettings set org.gnome.desktop.input-sources xkb-options "@as ['caps:escape']"

Fonts — disable embedded bitmaps. See Fonts.

Desktop - Gnome

Disable Wayland

Wayland is improving, but still some hickups with the following applications:

Synapse (constant pop up inhibiting shortcuts), and global shortcut not working (but we could set up a gnome shortcut Ctrl-Alt-Space with /usr/bin/synapse as command).

To disable:

At startup screen, select the user.
Click settings icon in bottom right corner, and select "Gnome on X.Org"
Login with the user and logout.

Gnome extensions

Notes

To install an extension using apt (recommended):

Install the package gnome-shell-extension-*.
Restart gnome shell (Alt-F2, then r).

To install an extension using chromium:

Install chromium and extension:

sudo apt install chromium chrome-gnome-shell   # Since U18.04, to manage Gnome extension in Chromium / FF.
# Alternative: install 'Gnome Shell Integration' from https://chrome.google.com/webstore/.

Visit https://extensions.gnome.org/, and search for the extension.

Enable and configure extensions in Extensions (recent Gnome)

Older Gnome, use Gnome tweaks (package gnome-tweaks).

AlternateTab

Debian - Since BookWorm: APPLICATION NO MORE NEEDED.

Instead, settings → keyboard shortcuts Set Alt-Tab to Switch windows instead of Switch applications.

Debian: Install from Chromium: AlternateTab
Ubuntu: press Super key, then AlternateTab, it will be installed automatically. This might require installing sudo apt install gnome-tweak-tool [5].
This extension fixes the annoying Gnome Alt-Tab behaviour that group windows from the same application.

System-Monitor

Install using apt (store, (github)

sudo apt install gnome-shell-extension-system-monitor
# Restart Gnome and enable with Tweaks

This replaces applet indicator-multiload that no longer works since Ubuntu Bionic.
If installed from store, requires the following packages:

sudo apt install gir1.2-gtop-2.0 gir1.2-networkmanager-1.0  gir1.2-clutter-1.0   # Ubuntu
sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0  gir1.2-clutter-1.0               # Debian

Note: the indicator may conflict with owncloud client (no longer visible), however this seems to be fixed with laster appindicator.
Selects memory, cpu, network, width 50px, and DO NOT show text.

Ubuntu appindicators / Appindicator and kstatusnotifieritem support

Install using apt

sudo apt install gnome-shell-extension-appindicator
# Restart Gnome and enable with Tweaks

More Pixel

Install using apt:

sudo apt install gnome-shell-extension-pixelsaver
# Restart Gnome and enable with Tweaks

NOTE: This works only in X.Org ! (at least under Debian Bookworm).

No title bar (Gnome-shell <= 3.30)

Install from the store (No title bar)
Revive Unity-like merging of window title bar with desktop top bar.
Caveat: Window's menu is not merged [6]
Gnome 3.38: we have to use fork from kendling/no-title-bar to fix for No JS Module 'tweener' found in search path.
Alternative: gnome-shell-extension-pixelsaver.

Gnome Global Application Menu (Gnome-shell <= 3.30)

Install from the store (Gnome Global Application Menu)
AVOID 'ALT' KEY STEALING FOCUS → In extension configuration (via Gnome Tweaks), Go to main menu, click on Alt, then Backspace to remove the shortcut. Breathe again.
To merge application menu in top title bar.
As a side-effect, this extension fixes the owncloud-icon-not-showing bug.
Recent alternative: https://github.com/gonzaarcr/Fildem

Custom Hot Corner - Extended

Install from the store ([7])
Set Show activity for all top corners on both monitors.

Gnome theme

We install a Mac OS theme.

Enable Gnome User Themes

Open Gnome tweaks, and enable extensions User themes (this enable theme selection for Shell' in Appearance).

Mojave light theme (Debian Buster / Bullseye / Bookworm)

Guide on OMG buntu.
Download and install McMojave:

sudo apt install gtk2-engines-murrine gtk2-engines-pixbuf
sudo apt install libglib2.0-dev-bin                             # Needed to install gdm theme
git clone https://github.com/vinceliuice/Mojave-gtk-theme.git
cd Mojave-gtk-theme
./install.sh
sudo ./install.sh -g

In Gnome tweaks → Appearance → Applications, select Mojave-light.
In Gnome tweaks → Appearance → Shell, select Mojave-light.

La Capitaine Icon Pack

Download and install:

mkdir -p ~/.icons
cd ~/.icons
git clone https://github.com/keeferrourke/la-capitaine-icon-theme.git

In Gnome tweaks → Appearance → Icons, select La-capitaine-icon-theme.

Fonts

In Gnome Tweaks → Fonts, select the following fonts:
- Interface Text: Lucide Sans Regular 11 (was Cantarell Regular 11).
- Document Text: Lucida Sans Regular 11 (was Sans Regular 11)
- Monospace Text: Fantasque Sans Mono Regular 11 (was Monospace Regular 11)
- Legacy Window Titles: Lucida Sans Unicode Bold 11 (was Canterell Bold 11)

Launcher

We stick to Synapse with Ctrl-Alt-Space, but this requires either running X.Org or add custom keyboard shortcut in Gnome Settings (fuzzy mode in Albert is just broken).

Gnome tweak

Top bar → Application Menu → OFF.

Gnome Mouse

Go to Settings, Mouse, and enable / disable the following settings as wished:

Touchpad → Tap to click
Touchpad → Natural scrolling

When playing games, flat acceleration is recommended.
On Debian 10 with BT mouse, speed -0.2 gives best result.

gsettings reset-recursively org.gnome.desktop.peripherals.mouse
gsettings set org.gnome.desktop.peripherals.mouse accel-profile flat
gsettings set org.gnome.desktop.peripherals.mouse speed -0.2
dconf dump /org/gnome/desktop/peripherals/mouse/
# [/]
# speed=-0.20000000000000001
# accel-profile='flat'

Miscellaneous Gnome

Disable emoji shortcut Ctrl-Shift-E (interfere with Terminator).

Launch ibus-setup, and delete the shortcut for emoji.

Development packages

Install packages - development

sudo apt install gitk git-gui git-doc exuberant-ctags cscope ruby meld colordiff  # ruby for Vim plugin snipMate.vim

# Optional
sudo apt install gitweb git-svn

Optional packages

AutoFS

sudo apt install autofs

Mount mnemosyne shares as NFS autofs (see [8]) and as SMB autofs

Enabled/created the following automounters in /etc/auto.master:

/net                /etc/auto.net                   --ghost
/smb/mnemosyne      /etc/auto.smb.mnemosyne         --ghost
/smb/lacie-cloudbox /etc/auto.smb.lacie-cloudbox    --ghost

Create configuration file /etc/auto.smb.mnemosyne
Create SMB credential files /etc/auto.smb.mnemosyne.* (see man mount.cifs)
~~Created path for mount points:~~

~~sudo mkdir /net sudo mkdir -p /smb/mnemosyne # ls /net/mnemosyne # sudo mkdir -p /mnt/mnemosyne # for i in /net/mnemosyne/volume1/*; do sudo ln -s $i /mnt/mnemosyne/$(basename $i); done~~

Or recover settings from an already configured host:

scp griffin:tmp/autofs.tgz .                                        # Configure autofs
sudo tar -xvzf autofs.tgz
sudo cp etc/* /etc

If necessary, mount shares read-only: add option ro in /etc/autofs.smb.mnemosyne
Create a writable share in /etc/fstab:

sudo mkdir -p /mnt/mystique/local
sudo vi /etc/fstab            # Add the following line
# //mystique/local /mnt/mystique/local   cifs    noauto,vers=1.0,_netdev,noperm,iocharset=utf8,sec=ntlm,username=superwoman   0       0

Chromium

Enable Chromecast:

Go to chrome://flags/#load-media-router-component-extension
Set to Enabled.

Dropbox

Download from https://www.dropbox.com/install-linux

Courier

sudo apt-get install courier-imap courier-doc gamin
cd /etc/courier/
sudo vi authdaemonrc   # Set authmodulelist="authuserdb"
sudo makeuserdb
sudo vi userdb         # Restore pwd for user 'st' and 'peetersm'
                       # See Courier page to generate new
sudo etckeeper commit "courier config"
sudo systemctl restart courier-authdaemon

Firefox

sudo apt install firefox

Set Ctrl-Tab to show last tab. Either in Settings (Ctrl+Tab cycles through tabs in recently used order), or browse to about:config, and set browser.ctrlTab.previews to True.
Install extension Firefox#textern.

fzf

fzf is a very fast fuzzy-finder written in Go.

It is installed when installing vim plugins. To install it in bash:

git clone https://github.com/junegunn/fzf.git ~/.fzf    # Skip this step if already present
cd ~/.fzf
./install

Gpg

sudo apt install gnupg-agent pgpgpg

Added use-agent at end of ~/.gnupg/gpg.conf
Edit ~/.gnupg/gpg.conf as necessary.

KeePass

sudo apt install keepassxc            # Now using KeepassXC
# sudo apt install keepassx

We store the database on Owncloud, and sync to local git repository with cron.

Script private/kdbx/sync_from_owncloud.sh:

#! /bin/bash

BASEDIR=$(dirname "$(readlink -nf "${BASH_SOURCE[0]}")")
cd "$BASEDIR"

KDBX=work.kdbx
OWNCLOUD_DIR=~/owncloud/kdbx

if ! diff -q $OWNCLOUD_DIR/$KDBX $KDBX; then
    echo "Adding $KDBX to git..."
    cp $OWNCLOUD_DIR/$KDBX $KDBX
    git add $KDBX
    git commit -m "Sync keepassx db with Owncloud"
fi

Cronjob:

31 * * * *      chronic ~peetersm/private/kdbx/sync_from_owncloud.sh

Workaround

Set kbd layout to fix autotype bug ([9]). Create ~/.xprofile and /etc/skel/.xprofile [10]:

LibreOffice

Install latest LibreOffice by adding the PPA:

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt update

mDNS

sudo apt install libnss-mdns avahi-daemon mdns-scan

To scan:

mdns-scan

Machine should broadcast its ip address on griffin.local to all avahi clients. For some strange reason, avahi may append a -2 suffix to broadcast name. To avoid that, edit /etc/avahi/avahi-daemon.conf and set host-name variable:

host-name=griffin

In some cases, avahi may detect host name conflicts on the network where there isn't.

Oct 24 19:32:06 zavcxl0006 avahi-daemon[810747]: Host name conflict, retrying with griffin-2

One fix for that is to restrict the set of interfaces (here only wired and wifi) [11], [12]:

allow-interfaces=enp0s31f6, wlp1s0

There is yet another potential conflict with systemd-resolved [13], [14]:

Debian BookWorm: install from debian repository, version 0.6.1.

sudo pip3 install --upgrade pynvim
sudo apt install nodejs npm yarnpkg ruby-dev
sudo npm install -g neovim
sudo gem install neovim

# In neovim, run ':checkhealth' and fix issues if any
# ... ignoring python2 bindings
# ... ignoring perl bindings

Debian Bullseye: build from source, version 0.5.1.
Debian Buster: build from source, version 0.5.1.

# New / current instructions
# We use Neovim compiled from source, version 0.4.4
# ... use uninstall script to uninstall
cd / && sudo tar xvzf /path/to/nvim-0.4.4.tgz
sudo ln -sf nvim /usr/local/bin/vim
sudo ln -sf nvim /usr/local/bin/vi
sudo pip3 install --upgrade pynvim neovim-remote
sudo pip install --upgrade pynvim
sudo apt install ruby-dev
sudo gem install neovim

# Old instructions (using distribution neovim)
sudo apt install neovim
sudo pip3 install neovim-remote   # nvr, needed by Vimtex

See Neovim page for complete install instructions.

Workarounds and tips

# Fix clipboard timeout issue at startup:
vim /usr/local/share/nvim/runtime/autoload/provider/clipboard.vim
# +  elseif exists('$DISPLAY') && executable('xsel')
# -  elseif exists('$DISPLAY') && executable('xsel') && s:cmd_ok('xsel -o -b')

Create a file /usr/local/bin/ngvim:

#! /bin/bash
# We redirect stderr to silent error on keyboard binding failure
if [ "$1" == "-f" ]; then
    shift
    # Blocking call
    2> /dev/null exec /usr/bin/terminator -m --p nvim -i /usr/local/icons/neovim.png -u -T "$PWD" -x env COLORTERM=gnome-terminal nvim "$@"
else
    2> /dev/null /usr/bin/terminator -m --p nvim -i /usr/local/icons/neovim.png -u -T "$PWD" -x env COLORTERM=gnome-terminal nvim "$@" &
fi

Neovim / vim plugins are installed via vim-plug, which is part of the home git repository.

Set Neovim as alternatives for vim/viewer (useful for Midnight Commander).

sudo update-alternatives --config vi         # Select 'nvim'
sudo update-alternatives --config vim        # Select 'nvim'
sudo update-alternatives --config view       # Select 'view.nvim'

However the following plugins require extra configuration:

YouCompleteMe

This is the install script to enable the minimum features. Note that this is done automatically by vim-plug.

sudo apt install cmake
cd ~/.vim/plugged/YouCompleteMe
./install.py --clang-completer

cpsm

Run this script after installing the plugin with vim-plug.

sudo apt install libboost-all-dev cmake python-dev libicu-dev
cd ~/.vim/plugged/cpsm
./install.sh

NFS

NFS Server (nfs-kernel-server nfs-common rpcbind)||See NFS for more details; Created entries in /etc/exports. rpcbind replaces portmap since Oneiric.

Owncloud

Install owncloud-client.
Start the client, and make sure the client is started at login.
Make sure appindicator gnome extension is installed, or status icon will not show up.
If owncloud icon does not show, there is maybe a racing condition. We fix by delaying start by 3s.

sudo vi /usr/local/bin/owncloud-delayed        # Content as below
# #! /bin/bash
# sleep 3 && exec /usr/bin/owncloud &
sudo chmod 755 /usr/local/bin/owncloud-delayed
sed -r 's/^Exec.*/Exec=/usr/local/bin/owncloud-delayed' ~/.config/autostart/ownCloud.desktop

Use ~/owncloud instead of ~/ownCloud.

PipeWire

We follow instructions from Debian Wiki.

# Install WirePlumber and enable it
sudo apt install wireplumber pipewire-media-session-
sudo apt purge pipewire-media-session
systemctl --user --now enable wireplumber.service
sudo rmdir /etc/pipewire/media-session.d/
sudo rmdir /etc/pipewire

# Restart, check that PW took over
sudo shutdown -r now
LANG=C pactl info | grep '^Server Name'
# Server Name: PulseAudio (on PipeWire 0.3.50)

# Enable ALSA through PipeWire
sudo apt install pipewire-audio-client-libraries
sudo cp /usr/share/doc/pipewire/examples/alsa.conf.d/99-pipewire-default.conf /etc/alsa/conf.d/
sudo etckeeper commit "Enable ALSA through pipewire"

# Enable JACK through PipeWire
sudo apt install libspa-0.2-jack
sudo cp /usr/share/doc/pipewire/examples/ld.so.conf.d/pipewire-jack-*.conf /etc/ld.so.conf.d/
sudo ldconfig
sudo etckeeper commit "Enable JACK through pipewire"

# Enable bluetooth through PipeWire
sudo apt install libspa-0.2-bluetooth pulseaudio-module-bluetooth-

Relevant configuration files:

Bluetooth — /etc/pipewire/media-session.d/bluez-monitor.conf

Or per-user ~/.config/pipewire/media-session.d/bluez-monitor.conf

Workarounds

Disable speech in Firefox. Open about:config, and set the following keys to false, then restart Firefox. [15]

reader.parse-on-load.enabled false
media.webspeech.synth.enabled false

Samba

sudo apt install smbclient cifs-utils

Use package smbfs for u1204 Precise Pangolin and before

SSH

Create / restore private key *and* public keys (or we get a wrong format error):

ln -sf ../private/ssh/id_rsa_work ~/.ssh/id_rsa
ln -sf ../private/ssh/id_rsa_work.pub ~/.ssh/id_rsa.pub

If using bin/ssh-agent-refresh.sh:

touch ~/.use_ssh_agent

Terminator

sudo apt install terminator

Install the new terminator that depends on GTK3 (terminator-gtk3, version 1.97~ppa3).
On latest Debian, install patch for middle click on Wayland (Terminator).
See Terminator.
See Gnome Terminator for tips.
Set background to transparent 6% (through ~/.config/terminator/config)
Set scrollback to infinite scrollback
Custom geometry terminator --geometry=1220x720+100+100 (in application menu)
Font Lucida Console, 9 (on nxl67002ux / nxl67063ux), or Bitstream Vera Sans Mono Roman 9 (on nxl67063 Cygwin-X).
(not needed on trusty) Set terminator as default terminal for Ctrl-Alt-T [16]:

gsettings set org.gnome.desktop.default-applications.terminal exec 'terminator --geometry=1220x720+100+100'

On Debian, with Gnome, add new shortcut for Ctrl-Alt-T:

dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/binding' '<Primary><Alt>t'
dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/command' '/usr/bin/terminator'
dconf write '/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom0/name' 'Terminal'

Truecrypt

Unpack and execute binary from file truecrypt-7.1a-linux-console-x64.tar.gz (console) or truecrypt-7.1a-linux-x64.tar.gz.

Thunderbird

See Thunderbird.

tmux

Alternative to screen, but with support for multiple panes like terminator

Make sure that tmux is at least version 2.2. If not install it:

Compile 2.2-3 package from yakkety. See Package Management for instruction.
Compile from sources.

VirtualBox

sudo apt install virtualbox

Debian Buster

Mouse pad scrolling issue, and micro-freeze issues with vbox 6.04+ coming from distribution. As workaround we use Oracle (testing) packge (and ext-pack):

sudo apt remove virtualbox
sudo ./VirtualBox-6.0.5-129923-Linux_amd64.run

VMWare

See PipeWire for sharing audio (share the pipewire unix socket) with user vbox.

Wine

Wine (wine) See Wine page

XBMC

see XBMC

Zathura

Install

sudo apt install zathura

If Zathura is not used for PDF files:

# when using 'see'
echo 'application/pdf; /usr/bin/zathura %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap

# when using 'xdg-open' or midnight commander:
# -- was "org.gnome.Evince.desktop"
xdg-mime default org.pwmt.zathura.desktop application/pdf

Configuration

Install fonts

Fantasque Sans Mono

mkdir ~/.fonts
wget https://github.com/belluzj/fantasque-sans/releases/download/v1.7.1/FantasqueSansMono.tar.gz
tar xvzf FantasqueSansMono.tar.gz -C ~/.fonts/ --wildcards *.ttf
sudo fc-cache -fv

Apply common settings (see below)
Applications not from repositories:
- Panda glGo 1.4.1 (local page, does not work on Oneiric 64-bit)
Install latest updates:

sudo apt dist-upgrade

Restore scrollbar behaviour in GTK3 [17], [18].

Use Shift+Click or Template:Right click to get the jump to click behaviour.

cat >> ~/.config/gtk-3.0/settings.ini <<__HERE__
[Settings]
gtk-primary-button-warps-slider=false
__HERE__

Ubuntu 12.04

sudo vi /etc/default/apport                         # Disable apport by setting "enabled=0"
sudo etckeeper commit "disable apport"

Fonts

Antialiasing RGBA, Hinting Slight, Text scaling factor 1.00.

Application	Font	Selected font
Terminator	Monospace font	`Fantasque Sans Mono 9`
Gnome Terminal	Monospace font	`Fantasque Sans Mono 9`
Unity (desktop)	Default font	`Lucida Sans Regular 9`
Unity (desktop)	Document font	`Lucida Sans Regular 10`
Unity (desktop)	Monospace font	`Fantasque Sans Mono 10`
Unity (desktop)	Windows title font	`Lucida Sans Unicode Bold 10`
Firefox	Sans-serif (latin)	`Liberation Sans 16`
Firefox	Monospace (Latin)	`Fantasque Sans Mono 16`

For firefox, fonts are inspired from Mediawiki Vector skin -- typography refresh.

MIME

Use Chromium for SVG files:

# when using 'see'
echo 'image/svg+xml; /usr/bin/chromium %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap
echo 'image/svg+xml-compressed; /usr/bin/chromium %s; test=test -n "$DISPLAY"' | tee -a ~/.mailcap

# when using 'xdg-open' or midnight commander:
xdg-mime default chromium.desktop image/svg+xml

Debian

Add contrib non-free repositories to apt source [19].

Add sid release apt sources.

cat << EOF | sudo tee /etc/apt/sources.list.d/sid.list
# Unstable / Sid
deb http://ftp.debian.org/debian/ sid main contrib
deb-src http://ftp.debian.org/debian/ sid main contrib
EOF

cat << EOF | sudo tee /etc/apt/preferences.d/sid
Package: *
Pin: release a=unstable
Pin-Priority: 400
EOF

Install these packages

sudo apt install mlocate dnsmasq-base
sudo apt install libcanberra-gtk-module      # Fix truecrypt warning

We install Firefox 56 and Thunderbird 52.8 to preserve some important add-ons. These packages and their dependencies are no longer available but they can still be downloaded on http://snapshot.debian.org/:

sudo dpkg -i firefox_56.0-2_amd64.deb \
    libcurl3_7.52.1-5+deb9u9_amd64.deb \
    libevent-2.0-5_2.0.21-stable-3_amd64.deb \
    libhunspell-1.3-0_1.3.4-2_amd64.deb \
    libhunspell-1.6-0_1.6.2-2_amd64.deb \
    libvpx4_1.6.1-3+deb9u1_amd64.deb \
    thunderbird_52.8.0-1~deb8u1_amd64.deb
sudo apt install -f
echo "firefox hold" | sudo dpkg --set-selections
echo "thunderbird hold" | sudo dpkg --set-selections

Nvidia

See Debian wiki. Mainly:

Make sure the system is up-to-date (nvidia module will be compiled against kernel headers, which may fail if headers are no longer available).

sudo apt udpate
sudo apt dist-upgrade

Run nvidia-detect:

sudo apt install nvidia-detect
sudo nvidia-detect
# ...
# It is recommended to install the
#     nvidia-legacy-340xx-driver
# package.

Install the reported driver (eg. here nvidia-legacy-340xx-driver)

sudo apt install linux-headers-$(uname -r|sed 's/[^-]*-[^-]*-//') nvidia-legacy-340xx-driver

Run nvidia-xconfig to create a new xorg.conf file (!! This fails on Optimus systems. See wiki !!).

sudo apt install nvidia-xconfig
sudo nvidia-xconfig

Reboot

sudo reboot

More issues

Apparently driver nouveau gets loaded as well. Let's blacklist it:

echo blacklist nouveau | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/blacklist-nouveau.conf

Boot error: nvidia-persistenced[557]: Failed to open libnvidia-cfg.so.1: libnvidia-cfg.so.1: cannot open shared object file: No such file or directory.

We uninstall some packages:

sudo apt remove nvidia-persistenced libnvidia-cfg1:amd64 libgl1-nvidia-tesla-440-glvnd-glx:amd64 libglx-nvidia-tesla-440-0:amd64 libnvidia-tesla-440-glcore:amd64 nvidia-tesla-440-alternative

Workaround

Install custom udisks package, version 1.0.4-5ubuntu2.1fuu1, to fix unreadable DVD-RW. See udisks, or bug 635499).

sudo dpkg -i udisks_1.0.4-5ubuntu2.1fuu1_amd64.deb

Add the following to ~/.bash_profile and ~/.profile to Meta-key (Alt) not working and Midnight Commander displays Press any key... after each command when in tmux session [20]:

# This fix meta-key support and stop mc displaying "Press any key..." in tmux session
if [ $TERM = "screen" ]; then
    export TERM=xterm
fi
if [ -n "$TMUX" ]; then
    export COLORTERM=rxvt
fi

Had some issues around fcitx packages being held when upgrading from Debian Bullseye to testing (Bookworm). So I uninstalled the full package suite, also because I fear this package may interfere with editors.

sudo apt autoremove --purge fcitx fcitx-modules fcitx-config-common libfcitx5utils2

Restore / keep from previous PC

Here a list of items to restore from previous PC.

/home directory.

The easiest is to transfer with tar

# This requires the following line in /etc/sudoers on mypc.local:
#    Defaults     !tty_tickets
#
MYPC=mypc
MYUSER=user
stty -echo; ssh -t $MYUSER@$MYPC.local sudo -v; stty echo
sudo mkdir /home/$MYPC
ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system home)" | sudo tar xvCf /home/$MYPC -

/root directory

ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system root)" | sudo tar xvCf /home/$MYPC -

/usr/local directory

ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system usr/local)" | sudo tar xvCf /home/$MYPC -

/etc directory

ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system etc)" | sudo tar xvCf /home/$MYPC -

In particular:

Restore files from /etc/sudoers.d.
Restore gufw profile from /etc/gufw/Home.profile.

/opt directory

ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system opt)" | sudo tar xvCf /home/$MYPC -

/var directory, but excluding /var/cache and /var/log

ssh $MYUSER@$MYPC.local "(cd /; sudo tar cf - --one-file-system --exclude=cache --exclude=log var)" | sudo tar xvCf /home/$MYPC -

Alternatively, data to backup from /var

MySQL database
Docker images
crontabs (from /var/spool/cron/crontabs or for each user using crontab -l).
mail (/var/mail.

Configuration:

# List of packages
sudo dpkg -l > dpkg-l-$HOSTNAME-$(date +"%Y%m%d%H%M%S").txt
apt-mark showmanual > apt-mark-showmanual-$HOSTNAME-$(date +"%Y%m%d%H%M%S").txt

Miscellaneous

Optional - Fix flash issue

# Optional - Fix blue video in flash (see below for details)
sudo mkdir /etc/adobe

sudo etckeeper commit "Fix blue video bug in adobe flashplayer"

Install packages - optional

# Optional applications
sudo apt install gnugo qgo uligo cgoban quarry pgpgpg powertop

Synapse

# On Debian Buster / Bullseye
sudo apt install synapse
# Alternative / Ubuntu
# sudo add-apt-repository ppa:synapse-core/ppa
# sudo apt-get update && sudo apt-get install synapse

Start synapse → Preferences → click Startup on login
If Synapse does not show up on keypress, there is maybe a racing condition. We fix by delaying start by 3s.

sudo vi /usr/local/bin/synapse-delayed        # Content as below
# #! /bin/bash
# sleep 3 && exec synapse --startup &
sudo chmod 755 /usr/local/bin/synapse-delayed
sed -r 's/^Exec.*/Exec=/usr/local/bin/synapse-delayed' ~/.config/autostart/synapse.desktop

It may also requires to define a custom shortcut in Gnome. Still in preferences, set Activate shortcut to Ctrl-Alt-Space

Opera

sudo apt install opera

See Opera to fix apt key issues.

sudo passwd isma
sudo passwd emma

Flash

Flash Plugin 10 (flashplugin-installer)||
Enable Ubuntu partner repository if needed(deb http://archive.canonical.com/ubuntu lucid partner).
In case of error failure to download extra data files flashplugin-installer, try

sudo apt-get --reinstall install flashplugin-installer

(Old recipe:

sudo aptitude autoremove "flashplugin-*"
sudo aptitude install flashplugin-installer

)

broken— This is too unstable, see next solution — On Ubuntu 12.04 with NVidia card, there is a bug Flash video appears blue. That link recommends to update libvdpau1, but in my case it was already at the latest version. Instead the following did the trick (from bug 968647):

sudo mkdir /etc/adobe
echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null

Another solution is to disable hardware acceleration, by going into flash player settings. If the settings window is not clickable, first disable unity 3D (for instance with metacity --replace&)
