Comment 6 for bug 653714

I have exactly the same problem as the original poster, also with a D800 and wuxga 1920x1200

If it helps, I have noticed that sometimes my screen shows correctly (the graphics are fine and so is the cursor), perhaps when I log back on after the screensaver kicked in.

So it seems to me that everything needed to render correctly is likely installed.

Still, it is damn annoying not to have even a workaround and regretfully it is a show stopper for me.
