I have been able to get this to work (with small bugs) with X386-SGCS that came with 1.1 using the config lines wga Depth 4 videoram 2048 virtual 2000 2000 viewport 0 0 Chipset "86C801" Modes "norm" # Clocks 25 28 40 0 50 77 36 45 130 120 80 32 110 65 75 95 Clocks 1 2 3 4 5 6 7 8 130 10 11 12 110 "norm" 110 1320 1376 1536 1760 1024 1025 1030 1090 -hsync -vsync Note the comment line - clocks seem to be abnormally ordered on this card, and note that the syncs are explicit and inverted. (And actually make composite sync). Now we have 2.0 with Xaccel, which certainly looks wonderful but seems to insulate me from any useful control of the card; when I configure it up with plausible selections from the menu (mfreq64.vda, 801-2.xqa) it goes into 31 KHz, no sync mode, and CTRL-ALT-<+> won't budge it. Any suggestions? What's available to tweak on? Is there any more documentation around? I've done some plausible fiddles as vaguely indicated in the man pages, but have a dim understanding of what's happening.
