Public bug reported: 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). ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: Unconfirmed -- DRI broken on r128 on dual head r128 + i965 (non Xinerama) https://launchpad.net/bugs/75726 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
