I have a GDM-1950, not a Sun monitor.  It is a 5-BNC model (seperate
H/V sync).  I'm driving it with a Matrox Mystique-220 (which does
have sync-on-green, but I don't know if it has composite sync).

I use matroxfb for console (with the exact timings given through lilo,
so I can diagnose boot-time problems) and the SVGA X server for X.

FYI: Sun's video timings are:

ModeLine "1152x900x66"  94.5    1152 1192 1320 1528   900 902 906 937 -hsync -vsync
ModeLine "1152x900x76"  108.0   1152 1184 1312 1504   900 902 906 937 -hsync -vsync
ModeLine "1280x1024x67" 117.0   1280 1296 1408 1632   1024 1026 1034 1067 -hsync -vsync
ModeLine "1280x1024x76" 135.0 1280 1312 1376 1664   1024 1026 1034 1066 -hsync -vsync

(These were converted from a CG6 manual.)  The first line applies to
the GDM-1950, and probably the GDM-1962 also.  The 20" monitors should
handle at least one of the 1280x1024 modes.

If you plan on using windows, I'd recommend a matrox card.  The
windows driver allows you to tweak video modes in a via text
configuration file (mga.mon).  I was actually able to play Riven and
MMVII on my fixed-sync monitor.

(I have some 1962's lying around, but I never got around to making a
cable for them.)
