VGA Out on Dell Inspiron 8000 with XF86



My video card died on my desktop, so I've taken to using my laptop as a
desktop replacement for the time being. I've got all of my desktop
peripherals hooked up to the laptop without any major problems. My
monitor is hooked up and with a bit of coercing, works pretty well.
Unfortunately, the default XF86 configuration is for 1400x1050@65Hz. My
monitor can and does display this, but since it's a CRT it looks rather
bad. I'd LOVE to be able to run it at 1400x1050 at 85Hz but either the
video out or the monitor doesn't support it. (I can't tell which, but
I'm guessing it's the video.) I'd like to set it up for 1280x1024 at 75
or 85Hz, but since I'm using the Dell supplied XF86Config with the
specific ModeLine I'm not sure how to best go about it. Preferably, I'd
just be able to add 1280x1024 as a secondary resolution so that
Ctrl-Alt-Num+ will switch to it. Here's my current XF86Config-4. TIA.
