I recently upgraded to modular X11 on my Powerbook Alu 1.25 Ghz and after some time messing around, I eventually got DRI working. For one night :cry:.

In fact, it still works fine, but only for the root account now. I tested it as a user when I got it working, so something got broken since then (dunno what). My Xorg.log does not contain any new problem (there is still a block range problem reported, but it did not prevent DRI to work on the first day I got it working. In fact, it still does not for root.

I double checked I have the following my xorg.conf the following part:
Quote:

Section "DRI"
Mode 0666
EndSection


Here is the message:
Quote:

root $ glxgears

and:
Quote:

Any ideas ?

Mine says this:

Section "DRI"
Group "video"
Mode 0666
EndSection


Maybe add the video line and make sure your normal user is part of the video group?

I had already added myself in the video section but did not add the video line in the Xorg.conf (first time I see it). It works now! Thanks!

I am back to this thread... I thought the above suggestion in the xorg.conf had fixed the issue, but my feeling is wrong. It just turns out that sometimes it will work; sometimes it will not... :cry:

The only thing I remarked is that using the suspend to RAM of my laptop sometimes causes the DRI to be lost for the user account. Then, restarting X may bring it back, or may not. But I also remark, that sometimes, I would start and not get DRI as a user (root always got it). The error is still the "open DRM failed (Operation not permitted)" thing.

Any other idea ?
