I'm running Suse 9.1 (amd64 - 64bit) version on my Opteron machine. When debuging problems with my NVIDIA graphics card, I have decided to test also Matrox G550 (dual head) card which I was successfully using with 32bit version. I'm able to run Xserver, but without GLX support - libdri.a has unresolved symbol __glXActiveScreens and I don't see libglx or libGLcore other then comming from nvidia drivers.
Is GLX/DRI supported for Matrox G550 on 64bit linux? Did I missed some package I should install?
