[Bug 660980] [NEW] Incorrect dual display behaviour

 

Public bug reported:

Binary package hint: xorg

using ubuntu 10.10 on the hardware as attached by apport. Normally in
10.04 when I did dual display it worked fine. Now the display is
detected fine, but I cannot move any of the windows to the external
display. However i can move few pixels of them, they can be seen on the
left edge, like just a small piece of them.

My workaround is to "move" the external display below the main display,
then it works. I assume it can be some problem with virtual resolution ?

The external display is LG 24", 1900x1200 resolution.


Mirror works perectly fine, the problem is only with the dual head.
