Title:
Brightness settings stopped working after upgrade
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Trusty:
Confirmed
Bug description:
I upgraded from saucy to trusty on my lenovo g505s laptop. After the upgrade,
both the physical key and the brightness settings in the gnome-control centre
have stopped working. Whatever level of brightness i decrease it to, it always
stays on maximum.
I'm able to reproduce this only on kernel 3.13. Works as its supposed to on
kernel 3.12
