I have a "generic" S3-805 based VL bus card, running under XFree-3.1. I can
get it to work in standard VGA mode, and 800x600 works at a slow refresh rate.
X -probeonly finds a reasonable looking set of clocks - no programmable clock
generator problem, it seems. The probe shows an S3 rev C or greater. The only
major chip on the board apart from the S3 is a Chrontel CH8391V. Anyone know
what that is?
I have obtained the patchlevel 5 S3 server, have put Option "nolinear" in my
XF86Config, fiddled like crazy with the timings - all to no avail. I either
get a blank screen on my 15" digital super VGA (30-65 kHz horizontal, 50-100
vertical) or an extremely unreadable, horizontally torn, vertically unsynced
The same hardware works fine at 1280x1024 non-interlaced under Windoze.
I have no clues - what is going on? Any help or suggestions gratefully accepted
