I have had similar problems - If you have SLS release
0.99pl6, switch to the /usr/X386/lib/X11 directory.
The file Xconfig.sample contains the standard VESA
timings - cut and paste the timings tables into
your current Xconfig file, replacing the existing
one. These timings work with the tvga8900c. Next
make sure that you have the chipset line in Xconfig
set to "tvga8900c" - it won't work otherwise.
Finally make sure that the modes line reads
"1024x768" "800x600" "640x480" - or something
in that order(it determines the order and resolutions
that the card cycles through with the + and - keys).
Note that all of these I use on a 1 meg card - if your
card has less that 1 meg, it will probably support
lower resolutions only, so be careful!! If you have a
fixed frequency monitor, be doubly careful - improper
timings can burn it out! If you have a
multisync, you don't have to worry as much - it's very
hard to destroy a multisync monitor with improper timings.
One more note: there are two locations in the Xconfig file:
1 for the vga256 driver and one for vga2(mono) - you
should match up the specs mentioned above for both. The
chipset line need only by stated once.
