Comment # 1 on bug 94272 from Michel D�nzer

Looks like machinectl / polkitd is doing something funky wrt VTs: The first
time I run it, it switches away from X to an empty VT with just a blinking
cursor. However, the line

 (II) AIGLX: Suspending AIGLX clients for VT switch

only appears in the Xorg log when I switch to *another* VT, so apparently the
Xorg server/driver doesn't get notified about the first VT switch. As such, it
can't really be a graphics driver issue. Reassigning to Xorg for now.
