Description of problem: Direct rendering is enabled on a ATI Radeon X800 SE (R430) (PCIE) video card as reported by Xorg.0.log ("RADEON(0): Direct rendering enabled"), but GL does not provide hardware acceleration: $ LIBGL_DEBUG=verbose glxgears libGL: OpenDriver: trying /usr/lib64/dri/r300_dri.so libGL error: failed to open drm device: Permission denied libGL error: failed to load driver: r300 libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so libGL: Can't open configuration file /home/fedora/.drirc: No such file or directory. Version-Release number of selected component (if applicable): mesa-libGL-8.1-0.21.fc18.x86_64 How reproducible: Always. Steps to Reproduce: 1. Start X session. 2. Run 'LIBGL_DEBUG=verbose glxgears'. Actual results: GL falls back to using the "swrast" driver. Expected results: GL is using the "r300" driver. Additional info: - Issue has occurred intermittently during the F18 development cycle. - Installed components include: * kernel-3.6.0-0.rc5.git2.1.fc18.x86_64 * libdrm-2.4.39-1.fc18.x86_64 * mesa-libGL-8.1-0.21.fc18.x86_64 * xorg-x11-drv-ati-7.0.0-0.6.20120910git7c7f27756.fc18.x86_64 * xorg-x11-server-Xorg-1.13.0-3.fc18.x86_64

How did you start X?
I see the same problem nouveau Test Day: $ LIBGL_DEBUG=verbose glxgears libGL: OpenDriver: trying /usr/lib64/dri/nouveau_dri.so libGL error: failed to open drm device: Permission denied libGL error: failed to load driver: nouveau libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so libGL: Can't open configuration file /home/kparal/.drirc: No such file or directory. The desktop performance is *unusable*. glxinfo says I'm using llvmpipe, but it takes a second to refresh the screen for any action. Even typing it terminal is really hard. I followed https://fedoraproject.org/wiki/QA:Testcase_nouveau_restartx : I booted into runlevel 3 and executed "startx".
this is therefore a dupe of https://bugzilla.redhat.com/show_bug.cgi?id=806491 . We need to change the test case not to tell people to use startx. *** This bug has been marked as a duplicate of bug 806491 ***
