Can't use DRI and aiglx at the same time


I just installed FC5 on a laptop with an ATI Mobility 7500 video card (which is supported -- with 3D acceleration -- by the open source "radeon" driver). Running glxinfo shows that direct rendering is enabled.

So I tried to install the aiglx server using the instructions here. I installed the aiglx mesa and glx-utils packages, and started my new X server. But now direct rendering is no longer working! Every time I run the Xorg server, direct rendering works. Every time I run the Xair, server, it doesn't.

There are no errors related to DRI/drm in the Xorg.log files.

I enclose the beginning of the outputs of glxinfo (with the 2 different X servers):

With Xorg:
Code:
$ LIBGL_DEBUG=verbose glxinfo
libGL: XF86DRIGetClientDriverName: 5.0.3 radeon (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/radeon_dri.so
drmOpenByBusid: Searching for BusID pci:0000:01:00.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 4, (OK)
drmOpenByBusid: drmOpenMinor returns 4
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
libGL error:
Can't open configuration file /etc/drirc: No such file or directory.
libGL error:
Can't open configuration file /home/joe/.drirc: No such file or directory.
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
With Xair:
Code:
$ LIBGL_DEBUG=verbose glxinfo
libGL: XF86DRIGetClientDriverName: 5.0.3 radeon (screen 0)
libGL: OpenDriver: trying /usr/lib/dri/radeon_dri.so
drmOpenByBusid: Searching for BusID ęC◊
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 4, (OK)
drmOpenByBusid: drmOpenMinor returns 4
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
drmOpenDevice: node name is /dev/dri/card1
drmOpenByBusid: drmOpenMinor returns -1003
drmOpenDevice: node name is /dev/dri/card2
drmOpenByBusid: drmOpenMinor returns -1003
<snip>
drmOpenDevice: node name is /dev/dri/card254
drmOpenByBusid: drmOpenMinor returns -1003
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
name of display: :0.0
display: :0  screen: 0
direct rendering: No
TIA for any suggestions.

Solved. It seems to have been a bug in the X server. Upgrading to rawhide (instead of the Xair server in the instructions) solved the problem.
