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.
• 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

To Do

Issues

• Issue — No OpenGL support with nvidia. Check the links [6], [7]. This is needed for XBMC. See this page to test availability of OpenGL:

glxinfo | grep -i direct
# The result should be: 
#   direct rendering: Yes

Some useful commands:

# Should display which card is active and which driver is in use
# (The line 'driver=nvidia' does not appear though for RedDragon
lshw -c display | grep driver
#       configuration: driver=nvidia latency=0
#       configuration: driver=i915 latency=0

# Display information on the nvidia card
# (from https://github.com/Bumblebee-Project/Bumblebee/issues/21)
/usr/lib/nvidia-current/bin/nvidia-xconfig --query-gpu-info --nvidia-cfg-path=/usr/lib/nvidia-current

Potential solutions:

• Lost glx after first upgrade from oneiric alpha 2 install (bug 807209)
• How To Get Optimus Working On Ubuntu 11.10 (Oneiric)
• Install Bumblebee
• Report information to Nouveau Devs

The bug is actually due to lack of support of new NVidia's Optimus Technology:

sudo apt-get remove nvidia-common nvidia-current nvidia-current-updates nvidia-settings nvidia-settings-updates

• Issue — External headphone (jack) does not work
• Solved — See [8]. Edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf (and similar ...-2.conf files if any). Change the lines:

 [Element Speaker]
-switch = off
+switch = on
-volume = off
+volume = ignore
