Comment # 6 on bug 1099812 from Peter S�tterlin

Sorry, got too late yesterday to test....

So I've now updated to xorg-x11-server-1.20.0-545.1 from X11:XOrg.
As you suspected, it did not cure the problem:  Still the programs (quake) die
with the same error, and xrandr makes the screen unusable.

As I regard xrandr a central/crucial system component I raise the severity of
this one to major.  Revert if you think otherwise.
