Thanks everyone, i've fixed my backlight problem with following steps: 1) set options video brightness_switch_enabled=0 to /etc/modprobe.d/video.conf 2) compile and install patched gnome-power-manager
Hope this changes will go to upstream. The only minor problem is that gnome-power-manager is not using libnotify's baloons similar to sound adjustment one, instead it spawns widget in bottom-middle of the screen. -- Brightness controls skips Levels. https://bugs.launchpad.net/bugs/527157 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
