Description Sitsofe Wheeler 2004-12-07 07:28:07 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win95; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Description of problem:
When xorg attempts to start it tries to load the drm module but fails. The following is printed inside the /var/log/Xorg.0.log:
(II) MGA(0): [drm] drmAddMap failed
(EE) MGA(0): [drm] DRIScreenInit failed.  Disabling DRI.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start the default configured X

Actual Results:  drm module has problems loading so there is no DRI.

Expected Results:  drm module should have loaded an DRI should have been enabled.

Additional info:

Changing screen resolution or depth doesn't seem to help.

I'm having the same problem with xorg-x11-6.8.1-12.FC3.21 on FC3
x86_64 with both a Matrox G550 card and a Radeon 9200 card.  

2.6.9-1.681_FC3 #1 Thu Nov 18 15:13:22 EST 2004 x86_64 x86_64 x86_64

Same DRM/DRI errors as above.

Poster, you aren't using FC3 x86_64, are you?
Comment 7 Sitsofe Wheeler 2004-12-09 03:55:53 EST
No I'm not, I'm using FC3 i386

Xorg and dmesg logs of Radeon drm/dri failure
Comment 9 Mike A. Harris 2004-12-21 03:45:10 EST
The Matrox DRI hasn't worked for a number of X.org releases now
it seems, depending on the hardware.  There does not appear to
be an upstream maintainer for this driver anymore, so problems
don't seem to get fixed upstream anymore.  ;o/

I don't notice any DRI related errors in the X.org log, and no
DRM related ones in dmesg.  Does your /var/log/messages contain
any relevant oops messages or other DRM or AGP related errors?

AGP is aparently rather broken in our current kernels, so it's
possible there's a problem on the AGP side of things.

I recommend reporting the Matrox issue to X.Org via the
http://bugs.freedesktop.org bugzilla also, to maximize the
likelyhood of someone investigating it and fixing it sooner.
If you do, please paste the URL here and we'll track the issue
there as well.

Thanks in advance.

In reply to comment #4/5/8:

DRI bugs in general are either kernel module specific DRM issues,
or 2D or 3D driver specific issues on the X side.  Generic DRI
bugs that affect all hardware are extremely rare, so if you are
having a DRI bug report on hardware other than what is initially
reported in this bug report, it should be treated as a separate
issue, and if you believe they may be related, or be caused due
to common DRI code, AGP, or similar, you can indicate that in your
bug report when you file it separately.

As a side note, when attaching files to bugzilla, always attach
individual uncompressed files, one file per attachment, so they
are individually viewable by clicking on them in a web browser.

Comment 10 Sitsofe Wheeler 2004-12-21 05:02:07 EST
There are no DRM or AGP errors in /var/log/messages* . There are no
oopses in there either.

Re: lack of upstream maintainer
Ouch. It's a pity matrox can't help (maybe they have the usual
licenced IP problems).

Anyway, I filed this on fd.o -

I'll ping this bug again after a new kernel with agpgart fixes is
released to see if this problem goes away.

(II) MGA(0): Using overlay video
(==) MGA(0): Direct rendering disabled
Comment 13 Sitsofe Wheeler 2005-01-04 14:41:17 EST
This problem mysteriously went away after an update to kernel-2.6.9-1.724_FC3.
How should this be resolved? CURRENTRELEASE (even though it appears not to be
x.org problem)?
Comment 14 Dave Jones 2005-01-04 14:44:24 EST
possibly a bad interaction between the 4g4g patch. It's the biggest difference
over the previous release.
