Public bug reported: kernel: 2.6.24-20-generic arch: x86_64 fglrx: 8.7
Most programs using Opengl for output acceleration, give me this error (like vlc when it usees Opengl as output method): vlc VLC media player 0.8.6e Janus [00000350] main private error: option glx-shm does not exist libGL error: drmGetMagic failed libGL error: reverting to (slow) indirect rendering X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 163 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 58 Current serial number in output stream: 58 Wine got this some versions beyond.. with fglrx 8.6 8.5 and other kernels aswell. A Quote from winhq bug which is about the exact same error: libGL error: drmGetMagic failed libGL error: reverting to (slow) indirect rendering This is definitely an fglrx bug, and seems linked to opening more than one display connection. I can easily reproduce the bug with code like this: dpy = XOpenDisplay(); visual = glXChooseVisual(dpy); XCloseDisplay(dpy); ... dpy2 = XOpenDisplay(); ctx = glXCreateContext(dpy2, visual); /* fglrx reverts to indirect rendering */ I've tested the above code with fglrx versions up to 8.5, and it reproduces the bug 100% of the times. If you do not close the first display connection the bug still occurs, albeit not always. Several applications seem affected by this, including VLC Media Player. It might be worth it to check whether Wine uses multiple display connections.
