Here is a copy of the config file that I use with XFree86 4.1 (that
comes with RedHat 7.2) on my Satellite Pro 4600 with the CyberBladeXP
chip. Note that someone suggested using the XFree86 CVS to get the
newest version, but I believe in an earlier post (article 1346) it was
clear that that user was only getting a color depth of 16 with the
newest CVS (which is no better tha I get with the trident driver in
XFree86 4.1). Using the appended config file I can get a color depth
of 24 using fbdev. Simply by changing the "driver" to "trident" (and
changing the DefaultDepth to 16 I can use the trident driver with
16-bit color. As I mentioned earlier, with 24-bit color the trident
driver produces a noisy screen. That's probably just a matter of
finding a better modeline -- which I haven't dealt with yet.

Note that to use the following config file, I must boot with vga=792,
as Jacques recommended. Cheers, Bill
