Description Sven 2009-01-25 14:29:50 UTC

Runnign glxgears yields the following error:
Failed to initialize GEM.  Falling back to classic.

3D works, as long as it doesn't say
  Option Legacy3D "off"
in my xorg.conf.


I'm running the following versions of relevant components:
- kernel 2.6.28.1, dmesg says:
[drm] Initialized i915 1.6.0 20080730 on minor 0
- xf86-video-intel-2.6.1
- dri2proto-1.99.3
- mesa-7.3
- xorg-server-1.5.3


What seems to be wrong? I was told, GEM is supposed to work.

I was hoping some helpful error message or warning somewhere, but found nothing in any of the logs.

If you need more information, ask me.

Please attach Xorg.0.log and dmesg.

I have the same problem about "Failed to initialize GEM. Switching to classic mode."

intel driver 2.6.1
libdrm 2.4.4
x11-drm 20080710
xorg-server 1.5.3-r1

Xorg.0.log

Comment 4 David 2009-02-10 15:07:05 UTC

I'm experiencing the same problem in gentoo.

kernel 2.6.28-ri
mesa 7.3
intel driver 2.6.1
libdrm 2.4.4
x11-drm --> not in use
xorg-server 1.5.3-r2

Comment 5 Eric Anholt 2009-02-18 13:01:02 UTC

You've installed old out-of-tree DRM modules.  Don't do that, the kernel has the DRM modules.

I don't. I'm using plain kernel 2.6.28.5 without any x11 relevant modules.

Comment 7 Eric Anholt 2009-02-18 13:18:16 UTC

Sorry, I went from the only dmesg posted, which (if you're right) is someone with a different problem:

[   21.679826] [drm] Initialized i915 1.13.0 20080312 on minor 0
[   21.679845] [drm] Used old pci detect: framebuffer loaded
[   21.680319] [drm:i915_getparam] *ERROR* Unknown parameter 5
(out of tree module failure)

You'll need to attach your own dmesg and Xorg.0.log as I requested.

Your dmesg is truncated.  Are you using PAE maybe?

I will try to upload a new dmesg taken from /var/log/messages.

Yes, I am using PAE.

Comment 13 Eric Anholt 2009-02-19 11:18:46 UTC

GEM doesn't work with PAE because AGP isn't ready for addresses over 32 bits.

Comment 14 Alex 2009-02-25 11:05:54 UTC

I have the same issue, however, I know that I am not using PAE, I recompiled my kernel and PAE is marked as off. I will attach my dmesg and Xorg.0.log

Mass version move, cvs -> git
