[Bug 822548] Re: Can't use dual screen 1680x1050 side-by-side with fglrx while open source radeon works

 

** Description changed:

  Using gnome-display-properties, I can't setup a configuration to enable
  my dual 1680x1050 screens setup in a side-by-side landcape
  configuration: gnome-display-properties says that the virtual size is
  not adapted to the real size (3360x1050 is bigger that maximum
  1680x1050) (this is not the exact message as I can not copy it and I'm
  using Ubuntu in french).
  
  However this setup works well (at least when it doesn't lock up at
  startup, due to bugs) with the open source radeon driver.
