[Grml] How to Re-configure Video?

Hi, I had to use a different computer to setup the HD. Unfortunately the screen resolution is now different (setup was done with 1024*768, now the resolution on the target is 800*600).

This impacts the framebuffer and it's handling, in console mode not showing all lines, which is annoying.

how can I easily reconfigure on the target machine the LILO setup, so that even with framebuffer the display is ok?

regards peb
