Title:
   display acting up. overlay .. ?

Status in xorg package in Ubuntu:
  Expired

Bug description:
  With nvidia 331.113 I have to manually configure dual screen layout
  (by doing what precisely?). However, if I remove this manually
  configured layout it fails.

  With this WORKAROUND in place, sometimes both screens are on the same
  monitor and it scrolls sideways (may be due to manual configuration
  error).

  tested nvidia 346 same thing.

  With nvidia 304 my second monitor stopped working.

  With nouveau the mouse cursor is streaking, and the performance isn't
  as good as nvidia.
