I don't see a follow-up on this topic... I hope someone still has an idea. ----- Forwarded message from fr...@inua.be -----

The same box with the same CRT runs X in 1280x1024x16 (didn't try 1600x1200). Regarding Plan 9, I also tested it with: - a plain old VGA monitor: just a blank screen - a flat panel (vga connector): blank screen, "no signal" Can it be that this is a driver issue? I already tried to get more information using the -v and -V options of aux/vga. With -m vesa, I always got the following, no matter what resolution I asked: main->snarf vesa->snarf vmf 100 vmdf 0 vf1 0 vbw 0 main->load +vgactlw type vesa -vgactlw type vesa I also thought that I might get around it by using a specific bios-string (-b option to aux/vga) but I don't know what I could possibly use. What can I do to debug this further?
