Xorg ati video module

Xorg Intel video module

Xorg nouveau video module

Mesa-based DRI modules

For testing purposes you can temporarily switch to:
Xorg modesetting video module - basic modesetting fallback module
https://admin.fedoraproject.org/pkgdb/acls/bugs/xorg-x11-drv-modesetting
i.e.
$ cat /etc/X11/xorg.conf
Section "Device"
	Identifier	"video0"
	Driver		"modesetting"
EndSection

Check what's happening with:
$ cat /var/log/Xorg.0.log
