[Bug 579028] [NEW] VGA screen sometimes is croped and has dithering DVI Screen is always normal ATI x800

 

Public bug reported:

Binary package hint: xorg

Since updating from Karmic to Lucid, one Display in a Dual Monitor
configuration is sometimes cropped and has then dithering.

It is an ATI x800 (R420) graphic interface with two monitors one
connected to the VGA and one connected to the DVI connector.

I can not find any rules when the problem occurs. It started when first
booting after the update. Changing back to the old /etc/X11/Xsession.d
/98vboxadd-xclient file helped for soume obots but the problem reapeared
again. Now the problem comes up about every second time.
