Subject description: ... with ATI Radeon 9250 DVI/VGA graphics adaptor
 

I have hooked up a widescreen (1680x1050) TFT to the DVI port of the Radeon, and the Beamer (1024x768) to the VGA-port. I have an extenden desktop in a way that I can watch DVDs on the Beamer and still use the computer normally on the TFT.
All I did was change some parameters in the xorg.conf, which all have to do with the ATI driver options. I do not have any 3D support installed. Here is the relevant parts of my xorg.conf:
Code:

Section "ServerLayout"
   Identifier     "X.org Configured"
   Screen      0  "Screen0" 0 0
   InputDevice    "Mouse0" "CorePointer"
   InputDevice    "Keyboard0" "CoreKeyboard"
   InputDevice    "Pen" "SendCoreEvents"
EndSection
...
Section "Monitor"
   Identifier   "Monitor0"   #TFT
   VendorName   "Monitor Vendor"
   ModelName    "Monitor Model"
   HorizSync    31.5-48.5
   VertRefresh  60
   #UseModes     "Modes0" #monitor0usemodes
EndSection
Section "Monitor"
   Identifier   "Monitor1" #Beamer
   VendorName   "Monitor Vendor"
   ModelName    "Monitor Model"
   HorizSync    15-126
   VertRefresh  43-200
      #UseModes     "Modes0" #monitor0usemodes
EndSection
...

EndSection


Note that I did not mess around with the server layout section, still, both definitions for 'screen' are required, or it will fall back to 640x480 resolution on both displays, not a pretty sight. All options that I uncommented in the 'Device' section (except the AGPmode and fastwrite) are required, or results will be somewhat other than expected (icewm only on beamer, strange aspect ratio of fonts etc.). As monitor layout I made the radeon believe it is running with two TFT screens, since a Beamer is closer to a TFT than to a CRT.
Runs fine so far, Beamer is a Sharp Notevision PG M20X, TFT a BenQ FP202W.

I would be very pleased if you could post the output of ddcprobe and lspci on your system to help me improve the new X-Wizard (http://www.murga-linux.com/puppy/viewtopic.php?t=23468).

Thanks in advance!
