Hi,

Yes, this means that DRI and DRM are not being initialized. I had the same problem, but I can't remember the exact steps I took to resolve it. I beleive you need to load the module 'agpgart' if it is not already built into the kernel, and then load your agp chipset module 'via-agp' if that is the correct one.
agpgart is already built in the kernel. And I think via-agp is the right module.
I'm not sure :) But make sure you did a make modules_install as root, that should set up the module dependencies properly.
I compiled the kernel with kernel-package which handled it.
After you have loaded the module, check the output of dmesg to see if it successfully detected your chipset. I get something like:
agpgart: Detected AMD Irongate chipset agpgart: Maximum main memory to use for agp memory: 176M agpgart: AGP aperture is 64M @ 0xe8000000 ... agpgart: Found an AGP 1.0 compliant device at 0000:00:00.0. agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode agpgart: Putting AGP V2 device at 0000:01:05.0 into 1x mode
The module seems to be loaded :
$ lsmod Module Size Used by ati_agp 6476 0 amd_k7_agp 5836 0 via_agp 7168 1 ...
But I haven't got the same message (the second part misses): $ dmesg | grep agp Linux agpgart interface v0.100 (c) Dave Jones agpgart: Detected VIA KT266/KY266x/KT333 chipset agpgart: Maximum main memory to use for agp memory: 96M agpgart: AGP aperture is 64M @ 0xe0000000
I tried glxinfo with tcsh and I obtained the following information : $ setenv LIBGL_DEBUG verbose $ glxinfo > /dev/null libGL: XF86DRIGetClientDriverName: 4.0.1 r128 (screen 0) libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/r128_dri.so libGL: XF86DRIGetClientDriverName: 4.0.1 r128 (screen 0) drmOpenByBusid: busid is PCI:1:0:0 drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 4, (OK) drmOpenByBusid: drmOpenMinor returns 4 drmOpenByBusid: drmGetBusid reports PCI:1:0:0 libGL error: drmMap of sarea failed
Finally, I read the DriTroubleshooting, (http://dri.sourceforge.net/cgi-bin/moin.cgi/) but there were no information about my problem. It helped me to detect an unresolved symbol:
$ grep unresolved /var/log/XFree86.0.log
Symbol fbdevHWGetLineLength from module /usr/X11R6/lib/modules/drivers/r128_drv.o is unresolved!
(DRI is loaded in XF86Config-4 and libglx.so isn't present on my computer.) I don't agree the sentence : "If you've made it this far, glxinfo should be printing direct rendering: Yes"
Have you got any more ideas ?
TIA,
