No, the display is fine. I tried setting things up with system-config-display, but it made no difference. Everything is working, it's just a slower than FC4 -- but, it seems, only with GTK/GNOME apps. The slowdown doesn't happen with lyx-qt or nedit... that's why I suspect that the use of Cairo is the culprit.
I just read the info for cairo about it being a vector graphics library.I guess your card is using Mesa emulation instead of DRI. (or something like that)
If you reduced your resolution and color depth, does performance increase?I'll test speed on the Intel 815 later to see if it is noticeably slower than /fc4.
Sorry not helpful for your problem. Jim
