Bruno Beaufils, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.
** Description changed: 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. + 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).
