DRI broken on r128 on dual head r128 + i965 (non Xinerama)

[Peter Cordes]

My system: core 2 duo on DG965WH (onboard g965 graphics), AMD64 Edgy, 2.6.19-mm1. r128 pci card installed, too. Xorg 2D driver i810_drv v1.7.3 built from git source. libgl1-mesa-dri built with -fno-strict-aliasing from Edgy source.

 With a dual-head non-xinerama setup, dri works on the primary head (the g965), but on the r128 head it gives weird errors and doesn't work.

e.g. glxinfo
...
the info for screen 0

Error: nConfigOptions (3) does not match the actual number of options in\n __driConfigOptions (4).
...
check the attached strace for lines that start write(2, for its stderr messages.

dri works when the r128 is used as a single head (even though it's still not the machine's primary VGA).

You'll have to get the stdout and stderr messages from the strace, which was done with -s256 so they're all there. I didn't save the Xorg.0.log, either. I can probably use that setup again and reproduce it if you need more info.

BTW, glxgears, tuxkart, and others print the same errors and can't open their window. 2D and XVideo works fine.

Hi Peter,

It's been a while since you reported this, and I wanted to check if it's still an issue? Have you had a chance to test it against Hardy?

We definitely will need your /etc/X11/xorg.conf, /var/log/Xorg.0.log, and the output from lspci -vvnn.

 No. I haven't been using dual-head any more. I can give it a try if I
have some spare time and I'm rebooting my machine anyway.

Hi, I've been see this bug on other distros (Fedora 8). Maybe I can help you to repro it. Anyway, it's been bugging me for quite a while. I recently tried updating various suspect pieces (the ati driver and OpenGL bits) and it seems to have gone away. Perhaps looking at the changes in Fedora may show the problem.

I was having the problem when these were installed:

Jan 02 15:05:45 Updated: xorg-x11-server-Xorg - 1.3.0.0-37.fc8.i386
Jan 02 15:05:47 Updated: xorg-x11-drv-ati - 6.7.196-2.fc8.i386
Nov 26 15:20:25 Updated: mesa-libGL - 7.0.1-7.fc8.i386
Nov 26 15:20:26 Updated: mesa-libGLU - 7.0.1-7.fc8.i386

I upgraded to these, and it went away:

Feb 20 14:23:05 Updated: xorg-x11-server-Xorg - 1.3.0.0-40.fc8.i386
Feb 20 14:23:06 Updated: xorg-x11-drv-ati - 6.7.197-1.fc8.i386
Feb 20 15:27:35 Updated: mesa-libGL - 7.0.2-3.fc8.i386
Feb 20 15:27:36 Updated: mesa-libGLU - 7.0.2-3.fc8.i386

I didn't make any other changes.

It may be this bug: https://bugs.freedesktop.org/show_bug.cgi?id=10132

[Peter Cordes (peter-cordes)]

yeah, I submitted it upstream, too. I didn't mention it here, sorry.

[Timo Aaltonen (tjaalton)]

Seems to be fixed upstream and in Hardy.
