Description of problem: First, I really don't know whether this bug is reported against the right component or not. Then, the facts. Although DRI seems to initialize properly (as reported by Xorg.0.log), it cannot be used neither by e.g. AIGLX, glxinfo or glxgears. This is on an Itanium workstation with an ATI FireGL X1 (R300 chipset) graphics adapter. The following error is displayed: libGL error: open DRM failed (Operation not permitted) libGL error: reverting to (slow) indirect rendering As user emeric, ls -lZ /dev/dri/card0 gives: crw------- emeric root system_u:object_r:dri_device_t /dev/dri/card0 which seems correct to me. Furthermore, the DRI section in my xorg.conf file is as follows: Section "DRI" Group 0 Mode 0666 EndSection I've checked on a x86 Rawhide system: the DRI section is identical. This issue is present on ia64 since at least January 10th 2006 (the date I installed Rawhide on my Itanium workstation). Mike Harris suggested this could be an udev issue. So I filed bug #184045 against udev at that time, but none of the proposed solutions does the trick. Logging in as root or with SELinux disabled didn't help. I recently had the opportunity to put my hands on a Matrox G400 graphics adapter and put it into my Itanium workstation for testing purposes: same permission error, so it isn't related to the xorg-x11-drv-ati component. FYI, I have openSUSE Factory installed on my 2nd HDD from roughly one month now and DRI works. Well, it's highly unstable (glxgears crashes immediately and requires a reboot) but glxinfo doesn't report the permission problem and reports "direct rendering: Yes". A great difference between Fedora Rawhide and openSUSE Factory is that the latter is shipped with X.org 6.9. IIRC, X.org 6.9/7.0 share the same source code. So, either something broke DRI during the "modularization" of the X.org 7.0 code, or (if the X.org 6.9 and 7.0 codes are identical except for the modularization) this is due to one of the patches applied to the X.org 7.0 code by the Fedora maintainers/developers. Or maybe yet an other thing. I really don't know how to help further so am open to any suggestion in order to help finding the root of this problem. Version-Release number of selected component (if applicable): From the X.org.log file, X.org 7.1.0 How reproducible: Always Steps to Reproduce: 1. Invoke glxinfo or glxgears 2. 3. Actual results: Permission error Expected results: Working DRI :-) Additional info:
