Un-installed applications (by uninstall date):

[YYYY-MM-DD] Application (package) [YYYY-MM-DD] uninstalled (reason)

Simple Settings

  • [2009-10-19] - Enabled proprietary video device driver NVIDIA (version 280).
  • [2013-05-18] - Enable audio head-phone (see [5]). Edit file /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf as follows:
[Element Speaker]
switch = on
volume = ignore
  • Printer — add Canon network printer (select IPP network printer via DNS-SD for protocol).
    • Set Color Model to CMYK

Detailed System Settings

1st install

  • INSTALL LOG

File System

  • To be completed

Network

  • To be completed

Preferences

  • To be completed

Users

  • Added to group users (for write access to mnemosyne):
    mich

Printer

  • Go to http://localhost:631
  • Set default policy to abort-job (was on retry-job)
    • Go to Printers → Canon-MG5300-series → Administration → Set default options → Policies → Error Policy = abort-job

Detailed Application Settings

Screensaver

  • gnome-screensaver does not work anymore. It simply show a black screen
  • Use xscreensaver instead, and select glslideshow for a slideshow.
 sudo apt-get remove gnome-screensaver
 sudo apt-get install xscreensaver xscreensaver-data-extras xscreensaver-gl-extra
  • UPDATE ISSUES — viewer used by glslideshow maintains a cache at ~/tmp/.xscreensaver-getimage.cache. Delete that file when updating the set of images in the slideshow.

Using xscreensaver without OpenGL

  • Package chbg does not exist anymore.
  • I could build package xv, but it does nothing under xscreensaver.
  • Use package qiv. Add the following line in .xscreensaver:
  qiv -s -r -S -d 10  -f -u -l -t -i      \
          $HOME/Slideshow               \n\
  • Select qiv as screensaver.

Apparently qiv does not work well with sub-folders. I use the following script (autoln): 

#! /bin/bash
#
# Usage: autoln /path/to/file /path/to/second/file [...]
#
#        will create the following symbolic links:
#
#        _path_to_file         --> /path/to/file
#        _path_to_second_file  --> /path/to/second/file

while [ -n "$1" ]; do
    target="$1"
    symlink=${target//\//_}
    ln -ns "$target" "$symlink"
    shift
done

In the command line: 

find -L /home/mich/Slideshow -type f -print0  | xargs -0 autoln

Remote support

New method

We call remote the remote laptop (to which we will connect), and local, the laptop we connect from.

  • remote must automatically start autonoekeon.sh at boot:
#! /bin/bash

autossh -M 0 -f -N -n -q -R 54895:localhost:22 noekeon
  • On local, setup a 2nd SSH forwarding link:
autossh -M 0 -f -N -n -q -L 22221:localhost:54895 noekeon
  • On local, connect and starts the vnc server on remote:
ssh -p 22221 -L 5900:localhost:5900 -L 5631:localhost:631 mich@localhost           # if needed, add -L 5901:localhost:5901
# export DISPLAY=:0
# xhost +
#sudo x11vnc -safer -localhost -nopw -once -auth /var/lib/gdm/:0.Xauth -display :0
x11vnc -safer -localhost -nopw -once -tightfilexfer -auth ~/.Xauthority -display :0
  • Still on local, starts the vnc viewer:
#vncviewer localhost:0
xtightvncviewer -compresslevel 0 -bgr233 -quality 0 localhost:0
old solution — Troubleshooting on scarlet box
  • Open a browser, and go to local.gateway. Go to LAN servers. Check that port 12322 is re-routed to server's port 22
old solution — How to connect

(note: previous config used to send an e-mail to michael.peeters@noekeon.org with instructions, but this does not work anymore. Now it creates a gpg file on noekeon.org)

  • Download gpg file, then view content for instructions:
scpn @/mip.txt.gpg .
gpg -d mip.txt.gpg >mip.txt


old solution — Configuration on the server
  • Disable strict host key checking for noekeon (to allow ssh connection even if host key changed):
Host ftp.noekeon.org   noekeon
     User                    daemenj
     HostName                ftp.noekeon.org
     StrictHostKeyChecking   no
  • autonoekeon.sh is run automatically at logon:
#! /bin/bash

autossh -M 0 -f -N -n -q -R 54895:localhost:22 noekeon
To connect, first setup port forwarding, then connect via localhost:
autossh -M 0 -f -N -n -q -L 22221:localhost:54895 noekeon
ssh mike@localhost -p 22221
  • Port forwarding also allows to connect to router and cups server:
autossh -M 0 -f -N -n -q -L 8080:192.168.1.1:80 -p 22221 mich@localhost   # Access remote router      via localhost:8080
autossh -M 0 -f -N -n -q -L 8081:localhost:631 -p 22221 mich@localhost    # Access remote cups server via localhost:8081
  • Script on desktop to setup vnc remote (vnctunnelnoekeon):
#! /bin/bash

# Save current stdout / stderr
exec 3>&1
exec 4>&2

# Redirect stdout / stderr
exec > >(tee /tmp/stdout.tmp)
exec 2> >(tee /tmp/stderr.tmp >&2)

# Deleting current .ssh/known_hosts
echo "Deleting current .ssh/known_hosts"
rm .ssh/known_hosts

# Open a vncserver
echo "Opening a virtual desktop for remote desktop sharing..."
vnc4server :1 -geometry 1440x900 -depth 8 -rfbport 5901

# TRAP EXIT --> Will remove port forwarding and kill the VNC server
trap "upnpc -d 12322 TCP; vnc4server -kill :1; rm /tmp/vnctunnelnoekeon-tail-f.tmp" EXIT

# Tunnel the VNC + local SSH Server connection through noekeon ssh
# ... SSH tunnel will remain open for 5min after which it will be automatically closed if no connection is made
ssh -f -n -R12301:localhost:5901 -R12322:localhost:22 noekeon sleep 300
# Wait a bit so that error message don't mess up my text below...
sleep 2

To Do / Issues

opengl / hdmi / optimus issue

other issues

  • Issue — External headphone (jack) does not work
    • (see bug 978880)
    • Broken solution — See [10]. Edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf (and similar ...-2.conf files if any) (more links [11], [12], [13]). Change the lines:
     [Element Speaker]
-switch = off
+switch = on
-volume = off
+volume = ignore
    Update — this does not work. Settings are reverted after pulseaudio update. Moreover the bass speaker is not correctly handled.
    • Solved The solution is to install the latest Realtek codec from here, v5.18 (more information [14], [15], [16], [17]). To install, just un-tar and run given ./install script:
    tar -jxvzf ...
cd ...
vi install                   # install script has a bug, fetch exec at wrong place after untar
sudo ./install
  • To Do — Setup BEH (backend error handler) for CUPS
  • Issue — Cannot read movies from DVD-RW
    • Solved — Require patch on udisks (see Udisks).
  • Issue — Sometimes keyboard in US layout
    • Temp fix: Add bin/setkbmap.sh and run it at startup:
    #! /bin/bash setxkbmap be
  • Issue — Flash instability
    • Temp fix: Uninstall all nvidia drivers
    • Temp fix: Uninstall flashplugin-installer
    • Temp fix: Install dansguardian & privoxy to prevent access to underground/unstable sites
      • Setup local network proxy: localhost:8080
      • Idem in firefox
      • ! for thunderbird, select no proxy (if proxy configured in system parameters → network... incredible but true [18])
