[Bug 77768] resume from S3 slightly broken since kernel 3.10

--- Comment #6 from Chris Wilson <chris at chris-wilson.co.uk> ---
After the resume, the CRTC has a mode (1280x1024) but no output is connected to
it (reported through GETCONNECTOR). X decides that everything is disconnected
so switches off the spurious CRTC, sets up a fake 1024x768 fb and leaves kwin
to decide how to enable the outputs (and kwin doesn't handle a screen resize
very well...).

The root cause then is that the kernel bookkeeping is slightly off after
resume, in particular the connector->status.
