Description Bill Nottingham 2001-02-06 19:08:19 EST
According to /var/log/XFree86.0.log, DRI is enabled and functioning,
but according to glxinfo it's using the Mesa indirect renderer, and
3D is not accelerated.

This is using a G400.
Comment 1 Mike A. Harris 2001-02-06 20:25:36 EST
I'm not surprised by this at all.  mga isn't functioning on this card
at all for me period let alone snazzy DRI.  ;o)

Added to the mga todo list.
Comment 2 Mike A. Harris 2001-02-07 00:40:01 EST
Can you attach your server log and config Bill?  I want to try and
corelate some things..
Comment 3 Bill Nottingham 2001-02-07 00:53:53 EST
Not my machine. Trond will have to attach a log file.

Comment 10 Trond Eivind Glomsrxd 2001-02-08 20:33:38 EST
This is probably a permissions bug... when you're root, it works as before: Hard
X crash.

Comment 12 Trond Eivind Glomsrxd 2001-02-08 20:36:25 EST
Michael, the dmesg output indicates something weird in the drm driver...
Comment 13 Bernhard Rosenkraenzer 2001-02-09 20:01:44 EST
No problems here with a G200 and a G400, XF86 4.0.2-7, kernel 2.4.1-ac6 with a
couple of patches from the RPM
Comment 14 Stephen Tweedie 2001-02-10 07:14:18 EST
You need to have

Section "DRI"
    Mode 0666
Endsection

in the XF86Config-4 for DRI to be accessible by non-root users, btw, regardless
of whether the functionality actually works or not.
Comment 15 Bill Nottingham 2001-02-27 19:22:27 EST
the original cause of the bug (bad DRI permissions) is fixed now.
mga DRI is as schizophrenic as always.
