Disable Virtual Frame Buffering?

i have a bit of a problem. i'm running slackware 8.0 on a dell laptop and by default, slack uses virtual frame buffering in X. while in theory VFB is nice since it supports almost all vid cards, in practice is slows X to a crawl.

i managed to get my XF86Config file to use the proper drivers and whatnot for my IBM thinkpad, but no luck with the dell. i even copied my XF86Config file from my thinkpad to my dell, changed the appropriate values and still X uses frame buffering.

so how do i get X to run off the video card specifics and not VFB? here are my specs:

Dell Latitude L400
128 ram
rage mobility 128 (4mb)
slackware 8.0
xfree86 4.2.0

thanx :-)

do you have fbdev in the XF86Config file?

it is probably using kernel level support
you could compile the kernel without support

nope, no fbdev in the XF86Config file. i do have virtual frame buffering enabled in the kernel, but that's because i use it in colsole mode (in lilo.conf, vga=791) and i *think* i need that in order to operate in the console.

i've been working on this for awhile, and i'm stumpted.
