[ltp] External TFT with higher resolution on a IBM T40

hi,

NONE doesn't work for me. He used always the resolution of the
ThinkpadLCD.

This did the trick:
Section "Device"
    Identifier  "Card0"
    Driver      "radeon"
...
# This is the important one
Option      "MergedFB"              "True"
Option      "MonitorLayout"         "CRT, LVDS"
# worked for me!
...

Endsection

With this setup, the ThinkpadLCD is off and the external TFT uses the
high resolution.

I've wrote a script, which uses the right config-file on start of X.
The solution is not the best, but better than using the external TFT on
1024x768.

There is maybe a possibility to use different serverlayout.

I've tried this, but without luck so far.


Thx for your help

Konstantin
