"screen brightness remains at 100 %, no matter if the laptop is on AC power or on battery power"
This has been a reoccurring problem for me as well. you can remedy the situation by adding the power management brightness applet to your panel and adjusting the brightness that way. If you adjust it with the key board short cuts the computer will just override the setting. If you use power management applet the computer won't return to 100% brightness. -- Screen brightness regulation malfunctions https://bugs.launchpad.net/bugs/207809 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
