Comment 22 for bug 245383

A thread where a patch is proposed http://people.freedesktop.org/~ajax/patches/randr-deliver-events-dammit.patch
http://thread.gmane.org/gmane.comp.freedesktop.xorg/30567

Another thread where someone worked around the problem by reverting an upstream change in the
2.4.0 series (as mentioned on xorg ML).
http://www.nabble.com/-Cooker--xrandr-Issues-with-intel-2.4.0-driver-and-or-gtk%2B-td18639779.html
This person mentions that:

"I've fixed this on my system by reverting an upstream change in the
2.4.0 series (as mentioned on xorg ML).

I'll monitor the thread to see if a better fix presents itself.

New intel 2.4.0-2mdv should be out shortly. "

So maybe 2.4.0-2mdv will fix the issue?
