Anyone have modelines for 1280x1024 on the VS 17GS (or any VS 17)?

=> We have a ViewSonic 17GS here and are just using the standard modelines
=> that are generated when you run xf86config.  Works fine.  Were running
=> this display on a Diamond Stealth 64 DRAM SE with the S3 server.  

Well, it works just fine here, too.  Sort of.  There is a really light
streak down the left side of the monitor that only appears in X (not
Win95, etc).  I've been tinkering with the modelines myself, but haven't
had much success.

That sounds more like the infamous bug in the S3 Trio64V+ graphics chip
(used in some Diamond and STB cards), so the cause might be your
graphics card rather than the monitor.   Meaning no amount of tweaking
would get rid of it. There's a workaround in the more recent beta
versions of Xfree86, however.

I find it hard to believe it's a bug in the card when it works perfectly
in all modes in win95.  If it is a bug, it sounds more like it's a bug
in the S3 server.

I can't tell you how I came to these monitor timings any more, though.
