Hi,
I recently set up arch on my Sony Vaio Pro 13, and everything is up and running bar being able to set my screen brightness using xbacklight. Here is where I am at so far:
- Any xbacklight operations give me the 'No outputs have backlight property' message
- My /sys/class/backlight/intel_backlight/brightness file exists
- I can force brightness changes by using 'tee /sys/..../brightness <<< value, where value is any valid brightness I wish to set
- I created (from the template, using Xorg :0 -configure or something) a new xorg.conf and tried to use the workaround with settng the Backlight property with the following options:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "sna"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
But when I try to start X, the xorg.conf gives me issues, telling me:
Warning, couldn't open module intel
UnloadModule: intel
Unloading intel
How do I resolve this issue so that I can use xbacklight normally? Thanks.
