Re: Unresolved symbol in libdri.a (X.org)

# Louis LeBlanc:
 First my config:
 OS: 5.4-RELEASE-p8
 X.org version: xorg-6.8.2 (built from ports)
 video driver: nvidia-driver-1.0.7676_1 (built from ports)
 
 
 My xorg.conf (only including what I suspect is relevant:
 
 Section Module
 Load dbe
 Load extmod
 Load dri
  ^^
Remove this from you xorg.conf (see below why).


 Symbol __glXgetActiveScreen from module 
 /usr/X11R6/lib/modules/extensions/libdri.a is unresolved!

This is the result of the 'Load dri'-line above.

DRI is hardware accelleration for several *non-nVidia*-GPUs.
If you're using the nVidia-driver, DRI is useless.

In this particular case, libdri.a needs to resolve the
external symbol __glXgetActiveScreen, which simply isn't 
provided by nVidia's /usr/X11R6/lib/libGL.so. [1]

HTH,
Mario

Unresolved symbol in libdri.a (X.org)

[Louis LeBlanc]

Ok, I've done a good load of googling on this, and I've seen hundreds
of reports of this problem with X.org, but not a single solution.  I'm
at a loss.

First my config:
OS: 5.4-RELEASE-p8
X.org version: xorg-6.8.2 (built from ports)
video driver: nvidia-driver-1.0.7676_1 (built from ports)


My xorg.conf (only including what I suspect is relevant:

Section Module
Load dbe
Load extmod
Load dri
Load glx
Load record
Load xtrap
Load freetype
Load type1
EndSection

# Not compatible with glx, which nvidia wants, so no composite in KDE
# Section Extensions
#   Option  Composite Enable

EndSection


Now, the problem I'm seeing is in Xorg.0.log.  It appears there is
some kind of problem resolving a symbol somewhere, but I can't figure
out exactly where the problem is.

Here's an excerpt from Xorg.0.log:
...
(**) NVIDIA(0): DPMS enabled
(II) Loading extension NV-CONTROL
(II) Loading extension XINERAMA
(==) RandR enabled
Symbol __glXgetActiveScreen from module 
/usr/X11R6/lib/modules/extensions/libdri.a is unresolved!
Symbol __glXgetActiveScreen from module 
/usr/X11R6/lib/modules/extensions/libdri.a is unresolved!
(II) Initializing built-in extension MIT-SHM
(II) Initializing built-in extension XInputExtension
...

There are a couple other inappropriate ioctl warnings related to the
mouse and thumbball, though they are probably not related to this
problem.

Any ideas what the cause of this resolution problem is?

TIA
Lou
