When I tried Fedora 15 from Live USB, I could *not* start Gnome 3 (--> bad 3d
acceleration --> the same bug) [blank screen and the pinter]. I used uNetbootin
to create the Live USB, and even if I tried to add "noapic" to the boot line,
it didn't work. Also I tried killing the X server, running "export
vblank_mode=0" and "export CLUTTER_VBLANK=none" and restarting X server and
also didn't work. Of course, I didn't tried installing Fedora 15, and then
retrying the workaround, but at least from Live USB I couldn't make it work.

However, I noticed that when Gnome 3 loads and the freeze happens, and then I
press ALT+F2, kill gnome-shell, and then ALT+F8, the Gnome-shell elements (top
panel and dash) appear in the screen, but of course I can not use it because I
killed the process. It's may be a clue.
