Bug#610826: gdm3: Virtual Machines also waste CPU due to this bug

Package: gdm3
Version: 2.30.5-6squeeze2
Severity: normal


I have a virtual machine setup for remote desktop access, primarily through 
FreeNX but also VNC. I noticed that gdm3 and dbus-daemon would start using 
about 50% CPU. Xorg.0.log shows "Fatal server error: no screens found". Once 
this happens I can no longer connect with VNC since it goes through gdm 
(I just get a black screen). Users can still connect with FreeNX since it
bypasses gdm.

Thanks,
Brendan
