Description Karthik 2007-12-14 14:03:03 UTC
karthik@rishi:~$ xrandr  -q
Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 2048 x 2048
VGA-0 connected 1920x1200+0+0 (normal left inverted right) 519mm x 324mm
   1920x1200      60.0*+
   1600x1200      59.9  
   1680x1050      60.0  
   1280x1024      75.0     59.9  
   1152x864       74.8  
   1024x768       75.1     60.0  
   800x600        75.0     60.3  
   640x480        75.0     60.0  
   720x400        70.1  
LVDS connected 1280x800+0+0 (normal left inverted right) 0mm x 0mm
   1280x800       59.9*+   60.0

   800x600        60.3  
   640x480        59.9  

If I move my VGA-0 (1280x800) below LVDS everything is fine. 
 BEFORE: xrandr --output VGA-0 --auto  --pos 0x800 (OK)

The other way around the VGA-0 is garbled screen (LVDS is fine):
AFTER: xrandr --output VGA-0 --auto  --pos 0x0  --output LVDS   --pos 0x700

karthik@rishi:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1500, maximum 2048 x 2048
VGA-0 connected 1920x1200+0+0 (normal left inverted right) 519mm x 324mm

   640x480        75.0     60.0  
   720x400        70.1  
LVDS connected 1280x800+0+700 (normal left inverted right) 0mm x 0mm
   1280x800       59.9*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
S-video disconnected (normal left inverted right)

I tried switch off/on monitor - did not help. BTW, "--auto " seems very important. If I issue the same command without --auto the VGA-0 is dumped to a low resolution 640x480. Although, xrandr -q reports _high_ resolution.

VGA-0 is a Dell 2407 -wfp 

many thanks.

Please attach your xorg log and config.  Also does the problem persist with ati git master?
