Xorg – (X11R6 X server) freezes on dragging an icon on the desktop when the screen is not in 800x600 resolution. Starting Eclipse also freezes the Xorg in the final stage of Eclipse startup. The Xorg does not accept any input from keyboard/mouse, the screen is frozen, Xorg CPU usage is close to 100%. The rest of Linux works normally.
Tests with KDE and Xfce have lead to the similar (the same ?) problem with X server.

Linux & Xorg observation:
FC6 installation passed smoothly. Gnome came without any problem. System->Administartion->Display (hardware tab) shows nVidia corporation NV5 [Aladdin TNT2] that is correct. It is possible to set display to 1024x768 and higher, both 16 and 24 color depth.
