Before I rebooted (and even before I tried the CVS Xserver), my text consoles had died (gone all mysteriously multi-coloured), I figure because I was stressing stuff with the overlay surfaces and my buggy code. So, back to waiting for it to happen again, I guess. Sorry. -- Billy Biggs [EMAIL PROTECTED] ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

I built an X server from CVS and changed the watermark values to match what was listed in the PRM. No change. I see the green crap at 24bpp and at 16bpp, and even when I use Ctrl-Alt-+/- to go down to 640x480 it's there (and it gets bigger) :)I don't think it's related to the watermark value. It really doesn't look like it's anything my software could do. If I use SDL's software Y'CbCr conversion I don't see any crap, for example. Messed up. BTW, I've found for overlay surfaces that I must have the DRI module loaded, so, for reference, I'm currently running kernel 2.4.5. -- Billy Biggs [EMAIL PROTECTED] ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

That's one of the advantages of an overlay. Mark. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

Well, I would like to go to a better refresh rate (see http://www.dumbterm.net/graphics/refresh/ for some discussion). What about quality at 16bpp? Won't I still see banding? I'd assume the overlay would still output as 16bpp. I checked the watermark values, X calculates 0x22218000 but the docs say 0x22212000. Not sure if this will matter but I can try if you think it will help. (8 qwords stored in the FIFO vs 2 qwords stored in the FIFO). You really think it's the memory bandwidth? I am using PC133 RAM. -- Billy Biggs [EMAIL PROTECTED] ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
[Xpert]i810 Xv bugs
Hi, I watched a movie yesterday and forgot to shut off the screensaver. When it kicked in, X hung. An strace of the hung process showed alot of SIGALARMs and that's it. No interesting messages to the log. I can investigate further if you like and see what's up, I hope to get the CVS X stuff up this week so I can start looking into those Xv issues I posted earlier. Also, an annoyance. I see alot of thin little green horizontal lines that flicker all over the overlay surface. Any thoughts as to what those might be, or any reason they might be happening? I suspect it's some hardware defect and I should go buy another video card. If you like I can try to describe them in more detail, but it's basically about maybe 30 little single pixel high 20 pixel wide green lines that appear randomly about the scaled image.
