Does anyone else have a display problem with KDE and with i810 chip? By problems, I mean, that sometimes a couple of things become "pixelated". For example, the windows decoration will go from solid colors to pixelated. There are a couple of other things that would do the exact same thing. I have noticed this problem way back when Slackware switch from xfree86 to xorg. It only does that with KDE. I can't figure out why. Any suggestions? Thanks!

I get the same thing, but only after watching a movie in a window. I just minimize whatever window does it, then restore. Or if it is on the panel, I just slide it off screen, and back. If it's the wallpaper, I just switch desktops, then go back.

Sometimes the video gets corrupted. If it gets too bad, I just restart X

Thanks for the response. I'm still not sure why it does that. Weird...

Seems to be connected with the shared memory archtecture (at least on my laptop. More prevalent when other apps are running)

I've seen this personally and I couldn't find the link but I did see at one time where it was documented as "not to be fixed."

Here's a solution: find the cheapest PCI video card available in the discount bin of a local Mom and Pop computer shop for $5. No matter what it is, it's bound to be better than an i810!

I have a Dell Latitude C400 with one of these chips (mine is an i830) and there are a few things I can suggest:

1. Configure X to use a 16-bit colour depth. (as opposed to 24). Experience taught me that 16-bit is faster and more stable in X (both Xfree/Xorg), and on integrated graphics chips, the shared memory (especially PC100/PC133 SDRAM) is a BIG bottleneck! (separate video RAM is usually three times faster anyway)
2. Disable DRI support!! DRI always gives me problems. You will lose OpenGL support, but that's no big loss because DRI can be flaky anyway.
(To do this, simply comment out all references to DRI in xorg.conf)
3. Compile your Linux kernel with the correct /dev/agpgart module for your northbridge chipset. /sbin/lspci will tell you which northbridge you have (often the first line in the output).
Slackware's stock 2.4 kernel has the modules for all the northbridges anyway so only do step 3 if you're using your own kernel.

But I only get the graphics glitches when running video files. Particularly with the Xv driver. Go into the settings of your video player and select X11/software video rendering instead of Xv. Usually fixes things.

Another thing: Which version of X are you using?
I ask this because the Xorg 6.9 from linuxpackages.net is particularly broken with regards to chipset stability - and I don't think it's an official build either. I always use the official Xorg from the latest Slackware (xorg 6.8.2) and it seems to work OK.
