Bug Description
Not sure if this is an X bug or a Kernel bug, but it ONLY happens after a hibernate/resume cycle.
The system hibernates and resumes just fine. However, once resumed, the display is at least 3/4 black with only a strip on the right side being visible. The desktop is still there, just not visible. Imagine someone laying a blanket over the left 3/4 of the desktop.
Im attaching a picture I took to show you exactly what I saw.
Now, to work around this, all I have to do is suspend the system and resume from that. I tried using switch user (didn't try restarting X). But after hibernation, if I do a suspend/resume cycle, video is restored to it's former glory without losing any work that was in progress.
