External display setup with different screen resolutions
Hi,
I know this has been asked over a thousand times before, but I can't get
an external display to work properly. I'm running an IBM T41p with
Sarge, kernel 2.6.10, XFree 4.3.0 and fglrx 8.14.13.1.
Problem is: The LCD panel has a resolution of 1400x1050, the external
TFT has only 1024x768. I have managed to get the external display
showing something, but with the LCD panel's resolution which enables
scrolling.
The more I look for information on the web, the more options I discover
I have not heard of before... I'm getting confused and don't know what
else to look for.
I'd appreciate any help!
The relevant stuff in XFreeConfig-4 looks as follows:
Section "Device"
Identifier "Card0"
Driver "fglrx"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
Option "UseInternalAGPGART" "no"
# Found this option via Google on

# Should enabled clone mode
