How did you work out a non-X ubuntu? Installed an ubuntu server edition?
/dev/dri is supported by linux kernel, try this command to see whether there is
drm and i915 module:
lsmod | grep i915
Maybe you can update your linux kernel to latest version and try again.
Thanks,

Hi Weng,
I might be missing something, but it seems like the DRI is only available
together with X. That's why I'm specifically interested if you know how to make
/dev/dri appear in non-X environment.
On the other hand, I made all my exercises as root, and I've just figured out,
though, that I don't have /dev/drm either, even though kernel reports it was
initialized in my system:
Sep 23 10:15:24 srv1204 kernel: [ 0.879802] [drm] Initialized drm 1.1.0
20060810
That's what I'm going to dig next. Thank you very much again for your time and
patience.
Best,
Seva
