Fedora 14 (x86_64) on a Lenovo ThinkPad T510 an "nVidia Corporation GT218 [NVS 3100M]" GPU. I normally don't use my laptop's built-in display when it's at home, so I'm not exactly sure when it started, but I suspect that the recent update to KDE 4.6 was probably the trigger. I can boot my system and log in to GNOME just fine. Logging in to KDE, however, causes the brightness of my laptop display to become unusably dim. This happens whether or not the laptop is running on AC power. The screen does return to its normal brightness momentarily when I connect AC power, but it then returns to its dim state. The KDE brightness controls are still set to full brightness; I can use them to change the display from unusable dim to completely black and back. The only way I have found to restore the display to its normal brightness (until I log in to KDE) is to reboot. Anyone have any idea what might be going on? I really am completely unable to use KDE this way. :-( TIA! _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
