After the upgrade to 13.10 Saucy Salamander, the brightness controls stopped working. This worked fine from 12.04 throughout.
Does anyone have an idea how I can fix this? If not, can you point me at the right package to file a bug against?
Bug I filed so far:
Solutions I have tried:
Changed this line to several options:
GRUB_CMDLINE_LINUX="quiet splash acpi_osi=Linux acpi_backlight=vendor"
I also tried to use
xbacklight, which didn't work either.
xbacklight -get wouldn't return anything.
