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
