Description Kurt 2006-04-20 05:31:56 UTC

I am able to launch into my ICEWM desktop but only with DRI disabled 
in /etc/X11/xorg.conf. If dri is enabled then I get a black screen. The system 
is still responsive but only a Crtl-Alt-Del and the subsequent reboot that 
follows, will recover the screen.

Looking at /var/log/Xorg.0.log indicates that server startup hangs during dri 
initialization.

Xorg 7.0 works ok on this machine with dri enabled.
Kernel version is 2.6.16.5
libdrm version is 2.0.1

This is the xorg config file without DRI commented out.

Comment 5 Erik Andren 2006-04-20 16:11:50 UTC

I had a similar problem and were able to resolve it by updating to current mesa
cvs. 
Also try to see if disabling AIGLX helps.

Comment 6 Kurt 2006-04-22 03:51:25 UTC

I tried to compile with --disable-aiglx as well as compile with the server and
the via driver against cvs mesa.

I still get the same problem:

Just a black screen.

Of course commenting "Load dri" out of the modules section of xorg.conf solves
the black screen problem but obviously X is unaccelerated.

Using strace, it appears that the via driver spews errors about

"undefined symbol assert" 

then exits, leaving the screen black.

I am currently recompiling the server with debugging enabled.

Comment 7 Marcin Kurek 2006-05-03 03:17:58 UTC

This problem is caused by xf86_ansic.h removal. In the via_dri.c there is
assert() call but there is no assert.h included and this cause driver to fail if
dri is enabled.

The fix is realy trivial.

Comment 9 Kurt 2006-05-03 20:02:59 UTC

That patch fixed it. I had no idea it was so simple. Thanks

Comment 10 Joshua Baergen 2006-05-16 12:46:27 UTC

It doesn't look like this has hit CVS yet, so it's not technically fixed.  If it
is in CVS, it's a different patch from the one suggested here.

Comment 11 Kurt 2006-05-16 13:08:49 UTC

I wondered about that. I even came back to this page to reopen the bug. 

I take that you are also having issue with the same driver?

Comment 12 Joshua Baergen 2006-05-17 00:51:56 UTC

I'm not using it, but some Gentoo users are reporting the issue ( http://bugs.
gentoo.org/show_bug.cgi?id=130320 ).

Comment 13 Thomas Hellström 2006-05-23 09:08:11 UTC

Commited now.
I removed the assert().
Thanks,

Thomas
