I run my display at 80x50, too. I am running XFree86-Server V4.2.0_3,1, I have tried standard and various options on my XF86 configuration. No VESA and the daemon splash (as the card has no graphic mode to support anything fancier) and stable as of today. It will OCCASIONALLY sync when I switch to VT, but often does not. The last time I got it to re-sync, I lost the cursor. :-( On the whole, it seems pretty bad. I have a bunch more of these coming it, so I'd love to figure this out. Windows has no problems, so something there seems to work correctly. It's almost certainly an issue of the timing in the video driver, but figuring it out could be very tricky. I have seen no references to this problem on the XFree86 Xperts list, so it may be a FreeBSD only problem. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
