I am not sure if its a duplicate of bug #351756 because my virtual size is smaller than 2048. See attached Xorg.0.log.
After rebooting Xorg worked again.

Hi sroecker,

Thanks for including the attached files. Could you also include your /var/log/Xorg.0.log (or Xorg.0.log.old) from after reproducing the issue?

Here is the Xorg.0.log.

[Timo Aaltonen (tjaalton)]

[Steffen Röcker (sroecker)]

No, didn't see it again.

[Timo Aaltonen (tjaalton)]

great, closing as fixed.
