Hi, I'm crossposting this to xpert and debian bugs -- I hope all agree it's appropriate.
This email is in regards to problems already reported by many people with regards to i810, in particular when 2 X windows are used at the same time. See these links for more reference: http://www.xfree86.org/pipermail/xpert/2002-July/018980.html (and its thread) http://bugs.debian.org/cgi-bin/bugreport.cgi?archive=no\&bug=78908 (and all other bugs associated with it) I have some good news, and a plea for more help. I have narrowed down the culprits. There are 2 accelerations that cause major problems when 2 X servers are ran. I believe there are more thar are buggy in the same regards, but the problems ensued are not as severe as these. Both bugs are quite random (though there are ways to "stress" them into triggering faster, I deem). Both of them require a reboot of the computer (see caveats below, though). The two bugs are: ************ 1) Vertical lines: display becomes blank with some vertical lines To prevent this from happening, use the option: Option "XaaNoSolidFillRect" "On" To stress it, you may want to try running "xine" ("apt-get install xine-ui" for us debianzens). The unfortunate corollary of this is that xine does not run when this accel is disabled :^< -- it causes X to exit (another bug!)... 2) Loss of Signal: the screen goes *really* blank, as if the computer was shutdown. My monitor goes into DPMS mode. To prevent this from happening, use the option: Option "XaaNoScanlineCPUToScreenColorExpandFill" "On" I don't know how to stress this one. ************ My chipset is: silver:~# egrep "Chipset i810" /var/log/XFree86.0.log (--) Chipset i810e found I've been in contact with Neale Banks (thanks, Neale) who is also in the same predicament. Neale, though, has (I think) a 'i810d', instead. There are subtle differences between these chipsets: - He does not seem to face problem #2 (the problem itself is more 'rare', so it might be it's just lurking there...) - He needs a power off to fix the problem -- for me, a simple warm reboot does it One last thing: I tried using dosemu to reset the video card, but I was only partially successful: I got the text mode back, but not the graphical. Please let me know if there's any more info you'd wish me to provide. I'll see if I can hunt it even further...
