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
