Description Bill Nottingham 2001-02-07 00:08:19 UTC
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 2001-02-07 01:25:36 UTC
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 05:40:01 UTC
Can you attach your server log and config Bill?  I want to try and
corelate some things..

Comment 3 Bill Nottingham 2001-02-07 05:53:53 UTC
Not my machine. Trond will have to attach a log file.

Comment 10 Trond Eivind Glomsrxd 2001-02-09 01:33:38 UTC
This is probably a permissions bug... when you're root, it works as before: Hard
X crash.

Comment 12 Trond Eivind Glomsrxd 2001-02-09 01:36:25 UTC
Michael, the dmesg output indicates something weird in the drm driver...

Comment 13 Bernhard Rosenkraenzer 2001-02-10 01:01:44 UTC
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 12:14:18 UTC
You need to have

Section "DRI"
    Mode 0666

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 2001-02-28 00:22:27 UTC
the original cause of the bug (bad DRI permissions) is fixed now.
mga DRI is as schizophrenic as always.
