On my dell i6400 the bug is in manual change (by keyboard special keys). If I change brightness, this return at 100% after open gnome-power-manager or Idle or other. The workaround is set brightness in gnome-power-manager.
For me the solution of this bug is synchronize 'manual change' with brightness in gnome-power-manager. -- [gutsy] brightness always appears after Idle https://bugs.launchpad.net/bugs/122666 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
