I just wanted to test the new (gnome3) window manager "mutter" on rawhide. It seems to work, but still something seems to go wrong:
[liveuser@localhost ~]$ mutter --replace
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.
