Title:
Backlight stopped working after update of linux-image
Status in “linux” package in Ubuntu:
Expired
Bug description:
I am using Ubuntu 13.04, fresh installation from scratch, on a
MacBookPro10,1 (the one with Retina display). Two of my partition are
encrypted (swap and /srv on which /home is bind mounted).
Since some upgrade to linux-image-3.8.0-24 backlight control does not
work anymore. I am stuck with 3.8.0-23 in order to get something kind
of working (I have to go in sleep mode at least once in order to get
backlight control available).
I have the exact same symptoms than bug #1169376. The only difference
is that no proposed fixes work at all. The last "almost working"
kernel is 3.8.0-23.
I even tried 3.9.0-030900 "upstream" kernel with no success.
Sleep access is no more clean either. Sometime (more than a 1/3 of the
cases) I am not able to resume the computer after having suspended it
: sometime the computer is alive (I can ssh on it to shut it down
since restarting lightdm does not resurrect the screen) but the screen
is black, sometime it is not).
Everything was working fine with the first installation of 13.04.
