Shite@sinkhole.unf.edu informed me earlier that earlier Swan SVGA cards do not provide some clock timings thatnewer ones do. His timings: 25 28 40 36 0 0 0 45 (25 28 32 36 40 45 56 65 for mine with VCO chip) The setting I posted earlier *WILL NOT* work without a 32 Mhz clock timing! You *MUST* have it. Now for 36Mhz, I have another setting that is probably flicker-free to most people. I have tried it with my hardware and am using it now when I am typing this article. name clock horizontal timing vertical timing flag "752x564" 36 752 788 916 952 564 564 569 594 No special flag necessary. Be WARNED that this is specifically designed for NEC Multisync II (horiz. 15.5 ~ 35 Khz, vert. 50 ~ 80 Hz. both automatically) and 36Mhz clock timing! Unless you are sure that you have both, *DON'T* use it! The setting provides a 63.7 Hz refresh rate, so probably most people won't sense any flicker. The rule of thrumb, if I remember correctly, is that above 70Hz, almost *NO* one would sense any flicker. 60 Hz is marginal, even I can sense flicker quite easily at 60 Hz by turning away my head from my monitor. As you can try the following: (with NEC Multisync II and 36Mhz MUST be available!!) "768x576" 36 768 808 936 976 576 576 581 606 This one has 60.9 Hz refresh rate already, but a xterm -bg white -fg black & immediately showed that it was no good so I gave it up. Finally I would like to thank Thomas Roell again. His X386 is indeed *VERY* easy to config. Superb! Chin Fang Mechanical Engineering Department Stanford University fangchin@leland.stanford.edu
