Extension "GLX" missing

[yamnikov-oleg]

Good day. I'm experiencing an issue with optirun after updating nvidia driver. Trying to run optirun glxgears results in:

Xlib:  extension "GLX" missing on display ":8".

These are the lines from /var/log/Xorg.8.log, stating that some dependent library can't be loaded:

[  1463.604] (II) LoadModule: "glx"
[  1463.604] (II) Loading /usr/lib/nvidia-375/xorg/libglx.so

Running ldd /usr/lib/nvidia-375/xorg/libglx.so displays:

	linux-vdso.so.1 =>  (0x00007ffe2e0f1000)

Running locate libnvidia-tls.so.375.66 displays these paths:

/usr/lib/nvidia-375/libnvidia-tls.so.375.66
/usr/lib/nvidia-375/tls/libnvidia-tls.so.375.66
/usr/lib32/nvidia-375/libnvidia-tls.so.375.66
/usr/lib32/nvidia-375/tls/libnvidia-tls.so.375.66

The problem started appearing after an update of nvidia-375 package from 375.39 to 375.66.

I've tried reinstalling packages:

• bumblebee, bumblebee-nvidia
• primus
• libgl1-mesa-glx, xserver-xorg-core (as proposed by the Troubleshooting guide).
• nvidia-375

I've checked bumblebee config (here it is), it points to nvidia-375 directories. I've checked for settings of update-alternatives (here), they correcly point to mesa directories.

I'd hope someone could help me resolve the issue.

Edit: I'm sorry, here my system information:

OS: elementary OS 0.4 (based on Ubuntu 16.04) 64-bit
Nvidia card: GeForce GTX 850M

Same issue! I did notice that running under Prime those ldd not found links resolve (unsurprisingly), which I assume shows which of the two options should be used, but I couldn't work out a way to do same with Bumblebee.

That's on Ubuntu 16.04. You? Any thoughts on where to get a package of 375.39 from now?

@neilcsmith-net I'm on elementary OS 0.4, but that's basicly Ubuntu 16.04. I could not resolve the issue since posting it here, so I just removed bumblebee and switched to official nvidia-prime package :-\ It requires session restart when switching cards, but at least it's still being supported and updated.

[spam-and-abuse]

Exact same issue here :(.

Found a workaround.
Use sudo prime-select intel to switch GPU. Just in case if you used mesa.
Then add next lines to /usr/lib/nvidia-375-prime/ld.so.conf (or to the mesa conf if you don't want to use prime-select)

/usr/lib/nvidia-375
/usr/lib32/nvidia-375

This seems to be working in the ubuntu ppa of bumblebee 3.2.1-98, but the issue is still in this develop branch. Yes the workarround works, but please find out why this happens.

I also found, there are two different libraries with different size:

-rw-r--r-- 1 root root 13080 Mai  1 23:32 /usr/lib/nvidia-375/libnvidia-tls.so.375.66
-rw-r--r-- 1 root root 14480 Mai  1 23:32 /usr/lib/nvidia-375/tls/libnvidia-tls.so.375.66

This sounds a lot like the issue described in #759. In particular, I found this solution got things working for me.

With driver nvidia-387 I got a permission problem. It only works with:
optirun sudo glxgears
