Title:
[Dell XPS L322X] Backlight control problems (3.8.0-25-generic
#37-Ubuntu SMP)
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After upgrading to 3.8.0-20.31 kernel my backlight control stopped
working. It was working on previous versions of the kernel. I know
other people reported this bug before and that 3.8.0-20.31 kernel was
suppose to fix it; but in my case it was working before and this
update broke it.
