You probably have an incorrect /etc/X11/XF86Config-4 configuration - thus if you have the energy to edit this file you'll almost certainly get it going sooner or later, and you'll learn a great deal in the process
It will depend a great deal on your monitor and graphic card specs - the first thing I'd do is hunt around the net and find everything you can (resolution, horizontal and vertical refresh rates, graphics card make and model especially). Then switch to another terminal by pressing
CTRL-ALT-F3 and login as root (or, just boot up in rescue mode from the start, and login to a terminal from there). You can view your config file by issuing
Code:
cd /etc/X11
less /XF86Config-4
- use the arrow or page up/down keys to navigate, and press q to exit. You can then make a backup of your old config file, and then copy one that you've previously put onto a floppy (or cdrom etc.).
Code:
cp XF86Config-4 XF86Config-4.bak
mount /mnt/floppy
cp /floppy/XF86Config-4 .
One config file you might like to try is this one here
http://www.ahpcc.unm.edu/%7Esummers/...380/XF86Config if your model also has an ATI Mobility 128 AGP video card (as does the XL380). You can also read through the manual page for X (
man XF86Config-4 and edit the existing file - after backing it up, of course.
