Didn't find the time for that. But I googled the issue once more and it looks like that the issue will be fixed in 3.15. "Backlight control broken on Dell XPS13 w/ kernel 3.14-rc7" https://bugs.freedesktop.org/show_bug.cgi?id=76276 GregKH accepted a revert patch for 3.14 to fix the regression there too: http://comments.gmane.org/gmane.comp.freedesktop.xorg.drivers.intel/38181 Kind regards, Aiko -- :wq ✉ -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
