[Bug 644714] [NEW] Screen corruption waking from screen blank if no monitor present

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

My test environment has a standard HDMI switch to go between several
test platforms.  On this system, if it doesn't detect the edid data when
waking, it restores the screen in 640x480 resolution and appears as a
corrupted screen.  Allowing the system to go blank again and ensuring
the switch is set to it recovers ok.

This is logged in the dmesg log file.
