Hello,
On my system (Linux 3.3, booting in EFI mode, using Nouveau with
nouveau.noaccel=1 due to
https://bugs.freedesktop.org/show_bug.cgi?id=27501 ), I can't figure out
how to change the backlight or switch which of the two graphics cards (I
have an Nvidia 9600M GT and a 9400M, both are recognized by nouveau but
only the 9400M is ever used) Linux uses for the framebuffer or X uses
for the output. I have /sys/class/backlight/nv_backlight, and writting
to nv_backlight/brightness does change the value in
nv_backlight/actual_brightness, but no actual screen changes occur. I'm
using the in-tree staging version of nouveau, so I wasn't sure which ML
this should go to.
Cheers,
Shea Levy
