Hi,

I'm trying to use the new intel,mesa,libdrm from the git repository with
xorg-server-1.6.1.902_r1.

Although in Xorg.0.log the driver loads ok (here an excerpt from the log):
(II) AIGLX: enabled GLX_MESA_copy_sub_buffer
(II) AIGLX: enabled GLX_SGI_swap_control and GLX_MESA_swap_control
(II) AIGLX: GLX_EXT_texture_from_pixmap backed by buffer objects
(II) AIGLX: Loaded and initialized /usr/lib/dri/i915_dri.so
(II) GLX: Initialized DRI2 GL provider for screen 0
(II) intel(0): Setting screen physical size to 304 x 228

"LIBGL_DEBUG=verbose glxinfo" reports:
libGL: OpenDriver: trying /usr/lib/dri/tls/i915_dri.so
libGL: OpenDriver: trying /usr/lib/dri/i915_dri.so
libGL error: failed to open drm device: Permission denied
libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so

but in Xorg.conf I have the needed DRI section like this:
Section "DRI"
        Mode         0666
EndSection

So, what do I have to do, to have to correct permissions in opengl? Is
there a new section needed for DRI2 or do I need a newer xorg-server
version?

I'm using kernel 2.6.28-r3 without kms (but enabling kms does not solve
the problem I already tried that).

Thanks for any help with enabling opengl.

Marc
