I've instaled KNOPPIX 4.0.1 DVD on my Desktop PC.
It used to run FEDORA at 1280x1024 on TFT.
Now I'm running at 1024x768.
I've done the 'gtf 1280 1024 70' in order to get my config line and put it in XF86Config-4.
I started in root mode to use kxconfig to change the resolution to that.
Reboot and I'm back to 640x480.
What's the problem ? Any sugestions ?
