No more 3D in Xorg after update (ATI9200SE)
 

My system is Debian Etch, kernel 2.6.8-1-386, KDE 3.5, Xorg. 3D was working great with the DRI drivers. The official ATI drivers do not support my video (ATI9200SE IGP320M U1).
Not long ago Xorg become "modularized" and was updated automatically when updating the system (apt-get update, apt-get dist-upgrade). From then on I do not have a working 3D any more :| Is there a solution for this issue?
Is the problem related to the transition from hotplug to udev with the new kernels? (Also related to "modularized" Xorg?)


Thanks


P.S.
3D works with Ubuntu 6.06 with a recent kernel. I can see some fglrx parts installed.
In Debian I have same ati and agp modules loaded as in Ubuntu.

A guess.

Your xorg.conf file got changed during the automatic update of xorg ?

No change in xorg.conf
 

Nope, really no change in my xorg.conf file. I've also checked it again and even renewed it with dpkg-reconfigure xserver-xorg - no 3D :|
I've also searched the net many times since then - no success :| This video card is a rare one... If I could only find the problem. But everything seems to be working as usual - the modules are loaded, no error messages in dmesg... I might miss a module or something else or it just doesn't work because of something compiled in the new kernles...


Anyway, thank you jabfinger for your reply :]

It seems like quite a specific question :}
 

Hope anyone suggests something or gives me a link...


10x :)

Case solved partially... :)
 

Here's an intersting link in the Debian wiki. It helps making the 3D work on a Debian with a new kernel 2.6.16, for example. But it does not work for me for kernel 2.6.8...

Case Solved!
 

All the problems and solutions step by step here:

http://dri.freedesktop.org/wiki/DriTroubleshooting

The problem in my case was:

--------------------
If the driver complains about unresolved symbols:

libGL error: dlopen /usr/X11R6/lib/modules/dri/radeon_dri.so failed
(/usr/X11R6/lib/modules/dri/radeon_dri.so: undefined symbol: _glapi_noop_enable_warnings)

then your libGL is out of sync with your DRI drivers.
--------------------


By running:

LIBGL_DEBUG=verbose glxinfo

I could see that error and the directory where libGL searches for the drivers. It was:

/usr/X11R6/lib/modules/dri/
(and the radeon_dri.so in it)

When I start Debian in fail save mode, I have a working 3D and libGL searchs the following directory for the radeon_dri.so module:

/usr/lib/dri

According to the DRITroubleshooting guide, libGL must work with a specific version of the drivers, usually latest. So I've deleted the drivers in /usr/X11R6/lib/modules/dri/:

ffb_dri.so i830_dri.so mach64_dri.so r128_dri.so r300_dri.so s3v_dri.so sis_dri.so trident_dri.so
i810_dri.so i915_dri.so mga_dri.so r200_dri.so radeon_dri.so savage_dri.so tdfx_dri.so unichrome_dri.so

And copied those from /usr/lib/dri to /usr/X11R6/lib/modules/dri/. After restart of the X server glxinfo reported "direct rendering: Yes" and my 3D is working now :)
