I found kind of a workaround for this problem. 1. gedit /etc/default/grub 2. change: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
3. sudo update-grub 4. reboot 5. now the brighness controls works but there is no indicator on the upper right corner (I can live with that) I dont know what the option 'acpi=off' exaclty does....... so I dont know if it is a valid solution for the problem. (maybe something else wont work correclty - time will tell.) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/880096 Title: cant change laptop brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/880096/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
