(Fujitsu Lifebook A512 - Ubuntu 14.04 - Linux 3.13.0-24-generic x86_64)
Pressing Fn+F6 or Fn+F7 the brightness doesn't change.
WORKAROUND (found here http://ubuntuforums.org/showthread.php?t=2192471)
1) The command:
for i in /sys/class/backlight/*; do echo $i;cat $i/brightness;cat $i/max_brightness;done
shows this output:
/sys/class/backlight/acpi_video0
1
100
/sys/class/backlight/intel_backlight
4882
4882
2) Then I've created the /usr/share/X11/xorg.conf.d/20-intel.conf file to set the "intel_backlight" interfece, with the following lines:
Section "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
This makes the brightness shortcuts Fn+F6 and Fn+F7 work.
EXTRA INFOS
- I run "ubuntu-bug linux" on a new installation of the 14.04 in order to get informations of the original setup of the system. The workaround has been tried on another 14.04 installation on the same computer.
- I didn't install any extra packages. Everything we need to make the hot keys Fn+F6/Fn+F7 work is already in the system. It seems to be a "setup problem".. maybe related to backlight or xorg..
- The lines in /usr/share/X11/xorg.conf.d/20-intel.conf are just a copy/paste taken from the ubuntuforums.org topic. I've just tried to use it and luckily it worked.
