; Locale (at least since Debian 10 Buster)
* '''{{red|ATTENTION}}''' Using the locale <code>en_DK.UTF-8</code> break Wine Command Prompt (bad keyboard config).
: To fix that, for instance for ''PlayOnLinux'', edit file {{file|/usr/share/applications/PlayOnLinux.desktop}}

<source lang=bash>
sudo vi /etc/locale.gen
# ...
sudo locale-gen
</source>
* Edit {{file|/etc/default/locale}}, and add line <code>LC_TIME="en_DK.UTF-8"</code> [https://askubuntu.com/questions/920649/how-to-install-other-region], [https://serverfault.com/questions/17118/how-do-i-set-the-date-format-to-iso-globally-in-linux]

=== 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 <code>/usr/bin/synapse</code> 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.

;Notes
To install Gnome extensions on Debian:
* To install an extension using '''apt''' (recommended):
* There are {{deb|gnome-shell-extension*}} package, but installing these has no effect.
:* Install the package {{deb|gnome-shell-extension-*}}.
* To install extension, go to Chromium. If necessary, in Chromium, install the add-on ''Gnome Shell Integration'' (go to https://chrome.google.com/webstore/).
:* Restart gnome shell ({{kb|Alt-F2}}, then <code>r</code>).
* Gnome extensions can be configured through the Gnome Tweaks (package {{deb|gnome-tweaks}}).
* To install an extension using '''chromium''':
:* Install chromium and extension:
<source lang=bash>
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/.
</source>
:* Visit https://extensions.gnome.org/, and search for the extension.
* Enable and configure extensions in '''Extensions''' (recent Gnome)
:* Older Gnome, use '''Gnome tweaks''' (package {{deb|gnome-tweaks}}).


;AlternateTab
;AlternateTab
* Debian - Since BookWorm: APPLICATION NO MORE NEEDED.
* By default, Gnome {{kb|Alt-Tab}} will group windows from the same application. To get rid of this annoying behaviour and restore the good old one, install extension '''AlternateTab'''.
:* Instead, '''settings &rarr; keyboard shortcuts''' Set {{kb|Alt-Tab}} to '''Switch windows''' instead of '''Switch applications'''.
* Debian: To install it, go to ''Gnome Tweaks'' (package {{deb|gnome-tweaks}}).
* Debian: Install from Chromium: [https://extensions.gnome.org/extension/15/alternatetab AlternateTab]
* Ubuntu: press ''Super'' key, then AlternateTab, it will be installed automatically. This might require installing <code>sudo apt install gnome-tweak-tool</code> [https://askubuntu.com/questions/69776/how-do-i-alt-tab-between-windows-using-gnome-3].

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.

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
Systemd
  • Add ourselves to group adm to get journalctl log for the whole system
journalctl -b | head
# Hint: You are currently not seeing messages from other users and the system.
#       Users in groups 'adm', 'systemd-journal' can see all messages.
#       Pass -q to turn off this notice.
sudo gpasswd -a $USER adm
# ...logout
journalctl -
b | head

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

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
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.
On Xfce
  • In the shell:
setxkbmap -option caps:escape    # Note: caps:swapescape doesn't work for me (caps does caps+esc).
  • Permanent (not tried), edit /etc/default/keyboard:
XKBOPTIONS="caps:escape"

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/.
  • 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
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.
  • Built-in alternative: there is however also Gnome settings -> Multitasking -> Hot Corner.

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).

  • 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.

Miscellaneous Gnome

  • Disable emoji shortcut Ctrl-Shift-E (interfere with Terminator).
  • Launch ibus-setup, and delete the shortcut for emoji.
  • Disable gnome-software from autostarting (to reduce memory consumption) [8]:
# Disable Gnome Software autostart
mkdir -pv ~/.config/autostart && cp /etc/xdg/autostart/gnome-software-service.desktop ~/.config/autostart/
mkdir -pv ~/.config/autostart && cp /etc/xdg/autostart//etc/xdg/autostart/org.gnome.Software.desktop ~/.config/autostart/

Optional packages

AutoFS

sudo apt install autofs
  • Mount mnemosyne shares as NFS autofs (see [9]) 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:

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) [12], [13]:

allow-interfaces=enp0s31f6, wlp1s0

There is yet another potential conflict with systemd-resolved [14], [15]:

Oct 24 19:41:28 zavcxl0006 avahi-daemon[811344]: *** WARNING: Detected another IPv4 mDNS stack running on this host.

Midnight Commander

sudo apt instal mc
  • See reference page.
  • Use vi as standard viewer/editor.
  • Installed version from mc official repository to fix file highlighting issue.

neovim / vim

Install instructions:

  • 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:

# +  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. [16]
reader.parse-on-load.enabled false
media.webspeech.synth.enabled false

Recoll

See Recoll.

Indexing mails from another user requires that Maildir is readable. By default, Maildir are not group-readable (although see man maildirmake for more info). The simplest is to run a cron script:

# m h  dom mon dow   command
10 12 * * * bash -c 'find ~/Maildir -type d -print0 | xargs -0 chmod g+rx'

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
  • If Ctrl-Shift-O not working, See Gnome 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 [17]:
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.

Account configuration
  • Junk Settings -> Move new junk to: 'Junk' folder
  • Junk Settings -> DO NOT Enable adaptive junk mail controls (for localhost accounts only).
  • Set PGP key
  • Server Settings -> Message Storage -> Clean Up ("Expunge") Inbox on Exit
  • Server Settings -> Message Storage -> Empty Trash on Exit (for st@localhost only)
  • Synchronization & Storage -> Message Synchronizing -> DO NOT Keep messages in all folders for this account on this computer (for localhost accounts only).
Gui configuration
  • Select columns: Attachment, Correspondents, Date, then apply to all folders & children on all accounts.
  • For all account, select View, Unthreaded.
Troubleshoot
  • If getting error Incoming server already exists, just use an alias (eg. use 127.0.0.1 instead of imap.localhost, or use imap2.localhost, and add an entre in /etc/hosts).

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:

VirtualBox / VMWare

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.

Seee VMWare for module compilation.

Configure ACL for /data/d
# VirtualBox / VMWare uses /data/d as Windows D: drive. Since they run as user 'vbox', all files gets vbox/vbox ownership.
# Any user in group 'vbox' will access to files created by vbox.
# We use acl to set set default acl (group access vbox/rwx, mask rwx), so that vbox can also access any file created by other users.
# Note this also gives write access independently of umask setting.
# Only limitation is that moved / copied files will keep their original ACL.
sudo apt install acl
cd /data
sudo chgrp -R vbox d
sudo chmod -R g+w d
find d -type d -print0|sudo xargs -0 chmod g+ws
find d -type d -print0|sudo xargs -0 setfacl -m d:group:vbox:rwx

To fix group ownership in case of move / copy:

sudo chmod -R g+w /data/d; sudo chown -R vbox /data/d; find /data/d -type d -print0 | xargs -0 setfacl -m d:group:vbox:rwx

The same line could be run as a user cronjob, but this will only fix the files/folders that user owns.

# restore ACL for /data/d vmware disk
00 12 * * *      chmod -R g+w /data/d; chown -R vbox /data/d; find /data/d -type d -print0 | xargs -0 setfacl -m d:group:vbox:rwx

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

Safeweb

Create a custom user for safe browsing.

adduser --uid 1005 safeweb
  • Add ~/reset.sh script to HOME:
cat > ~/reset.sh << "__END__"
#! /bin/bash

# Some safety check
[ -f $HOME/.resetable ] || { echo "$(basename "$0"): error: HOME is not resetable ('touch ~/.resetable' to fix) -- aborting!"; exit 1; }
[ "$HOME" = "$PWD" ] || { echo "$(basename "$0"): error: HOME and PWD are different ('cd' to fix) -- aborting!"; exit 1; }

# Armageddon !

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 [21]:
# 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
