Other Help Topics :: Screen messed up, and
I'm guessing that when you say "...the machine video is a pretty generic built in Intel card" that you have something similar to the Intel 82852/855GM Integrated Graphics in my Dell D400.
If this is what you have, you could try XFree86.dsl with a suitable XF86Config-4 file - I can post the setup that works for me to get 1024x768 24 bit colour if you have the same (similar) integrated graphics.
Note also with my D400 the maximum I can manage with the built in DSL X manager is as follows:
855GM
-----
0x0101 640x480x8 pseudocolor +0x0200=0x0301=769
0x0103 800x600x8 pseudocolor +0x0200=0x0303=771
0x0105 1024x768x8 pseudocolor +0x0200=0x0305=773
0x0111 640x480x16 truecolor +0x0200=0x0311=785
eg - vga=785 will give 640x480x16
The problem was corrected by upping the "Onboard Video Buffer" in the BIOS of the Dell machine from 1mb to 8mb. Really odd though that this default setting works fine with Windows, but nothing I could pull out of the forums would allow me to get a usable color pallette on DSL. Anyway, changing it from its default setting to 8mb has made DSL a happy camper.
Ah, that would explain the screen being messed up - not enough memory. Good find on your fix!
In windows you probably had the intel drivers loaded so it would be different - unless you loaded XF86 like what Juanito posted.
