PBen Quoting Harald Koenig from Xfree86 on the problems *I* have with the S3 Virge GX: "yes, it's known -- but it's neither _why_ this happens at all nor I'm close to sure that it's a design/coding bug in the server. quite some time ago I had similar problems with other ViRGE cards too (I don't have any ViRGE/GX for testing) and I could track down the problem to the fact that plain reading from video memory in text mode (to save text mode fonts at startup) fails and returns bogus data." As you can see, it IS a well-known chipset -- buggy, but well-known. This does NOT appear to be an X problem or a Linux problem. I have a Virge DX that has a similar problem in Windows 98. I'm probably going to replace it with something else (My local computer store has some PCI Matrox cards on sale! G) John

Yeah you are right I can probably figure out my own problems from that information however I am actually interested more in why I seemed to get better video performance from RH5.2 There is a "known" bug in some implementations of the S3 chipset, according to xfree86.org. The problem *I* have seen is that it messes up the console mode text after quitting X. They attribute this to "plain reading from video memory in text mode (to save text mode fonts at startup) fails and returns bogus data." (Quote from Harald Koenig of Xfree86 team.) Now, a commercial server MAY fix this problem. Matter of fact, on S3's website they suggest Accelerated-X for Linux users. Perhaps if you switched to Accelerated-X (there's a 10-minute free demo you can download) the problems you've experienced would go away and the video performance would likely improve. John

What version of Xwindows? Does your card have an acceleration enabled under Xwindows? Does it have acceleration under Windows 95? If you answer these questions I think you can figure out your own problems. From what I hear XFree86 4 will be a lot faster. If you need the speed now check out the commercial X servers. Nobody said that video was a strong point of Linux. At least I haven't read anything like that! PBen
