Similar behavior on Kubuntu with guidance-power-manager on an HP Pavailion DV6000T. Closing screen can cause the backlight to shut-off altogether. Noting that the brightness level per guidance-power-manager is 0. Setting the brightness levels in guidance-power-manager makes the brightness change... but that does not make use of the brightness buttons (Fn-F7/F8 for this box). When I unplug the machine, the screen dims to where the BIOS thinks it should be for battery-power (as set by the Fn-F7/F8 keys the last time on battery). As soon as the "Switching to battery mode." knotify message comes up, the brightness changes again.... Killing guidance-power-manager does *not* fix the problem for me however... Can I shut off the power-manager handling of these events? and can I get the Fn-keys to work again? This all worked in Feisty. I just rebuilt the box onto a new hard drive this weekend. Mostly a good upgrade, but this is not good. -- LCD backlight turns off when between discrete levels, both from hotkeys and from dim-on-idle. https://bugs.launchpad.net/bugs/121833 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
