I have an Nvidia FX 5200 video card with an Athlon 2500 CPU and an Asus A7V8X-X motherboard. I am running SuSE 9.1 Pro with the 2.6.5-7.108 kernel. cat /proc/driver/nvidia/version shows I am running the 1.0-5336 nvidia driver. The card is set for 1280 X 1024, 24 bit color and runs fine for all my applications. When I type glxgears I get the error message extension "GLX" missing on display ":0.0" My XF86Config file does contain the line Load "glx" in the Module section The appropriate part of the XFree86.log shows the following: (II) NVIDIA(0): AGP 8X successfully initialized (II) NVIDIA(0): Setting mode "1280x1024" (II) Loading extension NV-GLX (II) NVIDIA(0): NVIDIA 3D Acceleration Architecture Initialized (II) NVIDIA(0): Using the NVIDIA 2D acceleration architecture (==) NVIDIA(0): Backing store disabled (==) NVIDIA(0): Silken mouse enabled (II) Loading extension NV-CONTROL (EE) NVIDIA(0): Failed to load GLX (WW) NVIDIA(0): Option "CalcAlgorithm" is not used (==) RandR enabled This shows that the GLX extension is not getting loaded. I notice that Nvidia has a new driver as of August 5, version 6111. Normally I have installed the drivers via YOU and online update. Trying this leaves the driver at 5336. My question is twofold: 1) Is there a parameter i should add to my XF86Config file that would get GLX to laod, or 2) should I install the 6111 driver via the alternate method (not using YOU). Is that likely to fix the problem of GLX extension not loading. Mike -- Michael A. Coan Woodlawn Foundation 524 North Avenue, Suite 203 New Rochelle, NY 10801-3410 Tel 914-632-3778 Fax 914-632-5502
