Brice, In XFree86 glxgears was a fairly reliable indicator of whether things were horribly broken or moving along well. Running flightgear flightsim would always parallel the performance, albiet much slower. In Xorg, that doesn't seem to be the case. However, if the wheels in glxgears are stepping, throwing bands of colors across my display, etc, then I *know* there is a problem. I always run glxinfo to see what the system thinks is actually out there. glxgears will run even if mesa is doing indirect rendering. Dual head works with the existing system. That I know for a fact. I now remember that I was just starting a disk driver for a VxWorks related system and needed both displays. The xorg.conf.no-dri is a config that actually runs dual-head. And GLX works with the same software. The xorg.conf.good I sent you is "proof" of that. However, I haven't seen both DRI/GLX *and* dual-head (although I've always been able to do both in the past). There has always been a trick to getting it tweeked just right so that they both work. This is the first time I haven't found an answer. But now I know that I can switch config files and have either one or the other, just not both--until this gets fixed. Right now I have finished writing my driver and one display is down and GLX is *very* important at the moment, so I'm now running that. (As long as I don't have a senior moment and forget to switch configs or over write one, then I'll be okay.) Thanks very much for your help. I hope the config files I sent you can help.

If you want to know whether DRI works, glxinfo will tell you (look for "direct rendering: Yes" on line #4).The difference was that earlier I had run glxgears as root!It might just be a problem with the permissions of /dev/dri/card0. xserver-xorg-core sets it to mode 666 now, while you needed a DRI section in xorg.conf to do that earlier.I believe, is not dual-monitor and has very washed out colors and blender runs! The version I was running is marked "no-dri". This one the dual-monitor works correctly, but has no DRI/GLX. I can use this until my second monitor gets back from repair.Dual-head with DRI might not be that easy to get. We have bug #362997 about that. Maybe the next mga driver with randr-1.2 support will help. Brice
