Package: update-glx
Version: 1.0.0
Severity: normal

Dear Maintainer,

After a recent update of the system (Debian 10, stable), which included updates
of
*nvidia* and *glx* packages, the GLX interface stopped working - Xorg's log:
------
[  2439.150] Loading extension GLX
(...)
[  2439.159] (EE) NVIDIA(0): Failed to initialize the GLX module; please check
i
n your X
[  2439.159] (EE) NVIDIA(0):     log file that the GLX module has been loaded
in you
r X
[  2439.159] (EE) NVIDIA(0):     server, and that the module is the NVIDIA GLX
modul
e.  If
[  2439.159] (EE) NVIDIA(0):     you continue to encounter problems, Please try
[  2439.159] (EE) NVIDIA(0):     reinstalling the NVIDIA driver.
-----
Reconfiguring using update-alternatives --config glx and setting as follows:
--------
# update-alternatives --config glx
There are 3 choices for the alternative glx (providing /usr/lib/glx).

  Selection    Path                       Priority   Status
------------------------------------------------------------
  0            /usr/lib/nvidia             100       auto mode
  1            /usr/lib/mesa-diverted      5         manual mode
* 2            /usr/lib/nvidia             100       manual mode
  3            /usr/lib/nvidia/bumblebee   95        manual mode
--------
did not help. Also, reconfiguring nvidia's drivers (which are set to
/usr/lib/nvidia/legacy-340xx), made no change.

I found out that the problem was with the library:
/usr/lib/xorg/modules/extensions/libglx.so

which is loaded by the Xorg server.
My system has the following libglx libraries installed:

# dpkg -S libglx.so
xserver-xorg-core: /usr/lib/xorg/modules/extensions/libglx.so
xserver-xorg-video-nvidia-legacy-340xx:
/usr/lib/nvidia/legacy-340xx/libglx.so.340.108
xserver-xorg-video-nvidia-legacy-340xx: /usr/lib/nvidia/legacy-340xx/libglx.so

and manual overwriting the
/usr/lib/xorg/modules/extensions/libglx.so
with
/usr/lib/nvidia/legacy-340xx/libglx.so
fixed the issue.

As far as I know, these drivers (340) have no support from NVidia anymore,
so I do not know whether it will be maintained for Debian, but maybe it is
still
worth to fix...

One more thing - the problem existed also before (I fixed this on my box
in the same way some months ago).

Hope it helps.

Regards,
Tomasz
