su to root and edit your /etc/X11/XF86Config-4 file. You might want to back up the old one first.
Your device section should look like this:
Identifier "Generic Video Card"
This works well for the LCD screen on the 600E:
Identifier "Generic Monitor"
The screen section usually has lots of entries but you wouldn't want to run it at any other resolution that 1024x768 unless you have an external monitor:
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
The rest is pretty straight-forward...like putting your countrycode (se for Sweden, de for Germany, etc) as the XkbLayout option under the keyboard input device section.
