All: I have just tried moving to Fedora 14 x86_64 using preupgrade. Upon launch of the new system, KDE is virtually non-responsive (I can get some response initially, but it quickly fades). Mouse pointer moves, but clicks do not seem to do anything. If I relaunch in KDE safemode, all seems well. Where should I start looking? Xorg.0.log shows no errors. Messages carries the following (which I don't think is relevant): Nov 4 11:33:33 george NetworkManager[1127]: <error> [1288884813.510342] [nm-manager.c:1331] user_proxy_init(): could not init user settings proxy: (3) Could not get owner of name 'org.freedesktop.NetworkManagerUserSettings': no such name The only other anomaly was that the lower right-hand portion of the screen showed a flickering white bar just to the left of the plasma bar. In addition, when I used alt-tab to switch between apps (during a brief period of responsiveness), one of the applications displayed was "plasma-desktop", which I had never seen before. I do use the proprietary nvidia graphics driver from ATRPMs, not the nouveau driver (though, again Xorg says this was loaded just fine). Any help or thoughts of where to look would be helpful.
