Bug#900503: xbacklight: Packagely solve the case of intel_backlight
Package: xbacklight
Version: 1.2.1-1+b2
Severity: normal
Dear Maintainer,
hello, i have an
asus x55v (intel video) and wanted to use xbacklight.
I got many case of failures :
xbacklight -inc 1
-> No outputs have backlight property
DISPLAY=`xrandr | grep ' connected primary' | awk '{print $1};'`
xbacklight -d $DISPLAY -inc 1
-> RANDR Query Version returned error -1
Therefore i search around internet, and there is 2 solutions which
doesn't imply to change the code of xbacklight.
1 - using xbacklight from https://github.com/wavexx/acpilight (or
some fork), which rely on /sys/class/backlight/*.
To use write on /sys/class/backlight/*/brightness, simple udev
rules have to be added in /etc/udev/rules.d/ (these rules are in the git)
2 - finding a way to setup automatically intel card backlight option
in xorg script.
Section "Device"
Identifier "Card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection
--------------------------------------------------------------------
(In fact i had 3 asus computers and every time the same things was
to reconfigure again and again. I stopped to use xbacklight and used
a sudo script just for myself... )
Hope these elements could help for intel video card computers.
Have a nice day.
