Hi people.
I have a very sad story that ends with my onboard video card ( X700 Mobility on an expensive laptop ) not working for any 3D 'stuff'. Here's a copy/paste of what I sent to the xorg list:
- If I start X with DRI enabled with xf86-video-ati, I get a hard lockup - usually instantly, but sometimes after a couple of seconds. I get lots of messages in my X log about "[mi] EQ overflowing. The server is probably stuck in an infinite loop." and "[mi] mieqEnequeue: out-of-order valuator event; dropping".
- If I start X with xf86-video-ati and DRI disabled ( 'Option DRI 0' in xorg.conf ), X startx fine and works for extended periods ( tested up to 1 day ).
- If I start X with fglrx, and DRI enabled, it works fine. But if I start compiz or anything 3D ( including glxgears ), I get *massive* corruption. Bits of windows are echoed all over the place. Everything works 'fine' other than this. If I kill compiz, everything works normally as with xf86-video-ati and DRI disabled.
The only positive news is that the textured video driver in xf86-video-ati works perfectly, and I believe this uses the 3D chip, so gives me some hope that it's a memory issue and not the 3D chip fried.
I should also note that this is absolutely not a software / config issue. I've installed various versions of Gentoo, Sabayon and Ubuntu, and all exhibit the same behaviour.
So ... the problem is a hardware one. I assume it's either the 3D chip or memory. If it's the 3D chip, there's not much I can do. But if it's memory, I should be able to blacklist part of the memory or something, right? I know that the open-source drivers ( used to / still do? ) allocate half available memory to 2D and half to 3D, and I'm hoping that this is the explanation for why 2D is working and not 3D ( though I suppose this is largely wishful thinking ).
Is there any hope? Are there any driver options for xf86-video-ati, xf86-video-radeonhd or fglrx that would allow me to blacklist part of my video card memory?
Thanks
Dan
