That bug certainly was GNOME specific: it was a bug in gnome-power-manager 's logic. There's no way that specific bug could affect KDE, unless somehow you're running g-p-m in KDE. If you're seeing a similar issue in KDE, it must track down to a different bug, so please file it. Be aware, though, that the display dimming somewhat when you disconnect the AC power is 'normal': both KDE and GNOME do this to save battery power. The bug in this case was that when you re-connected to AC the brightness did not increase again, but if you then disconnected from AC once more the brightness would decrease further - so you got stuck in a descending spiral of darkness until the screen was stuck at its lowest possible brightness setting until you adjusted it manually or rebooted. If the screen dims somewhat (to, say, 50%) when you unplug, goes back up to 100% when you plug back in, then dims back to 50% when you unplug again, that's intended behaviour and not a bug (though if you don't like it, it's configurable). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
