[mythtv-users] Screen blank Video all messed up

[Paulin]

I"m having a few weird video issues that I'm hoping someone can shed some
light on.

First I've been having a problem that pops up every once in a while and the
only way to fix it seems to be reboot the box.  The problem, and I'm not
sure how to really describe it, is that something will happen to the video
(blank screen) and I'll restart gdm (stop gdm then start gdm).  When it
comes back the desktop has some pixel discoloration spots.  When the
frontend loads, the menu screen is completely distorted (imaging taking a
weaving and pull every third row to the right, and then every first row to
the left).  That is how the screen looks.  Nothing can be seen from it.
Exiting the frontend and the desktop is visible (more clear) but still has
issues..

The second issue is that tonight, my wife was watching a show and about 30
minutes in the screen just went blank.  The sound continued fine.  I
restarted GDM.   She then began watching her show.  It then happened again
about 10 minutes later.  I then restarted GDM again and that is when the
pixelation issue occurred.

So any thoughts?  I'm not sure where to being looking for the problem.

Thanks,
steve
