I have Linux Mint 17. I updated my xserver from 2 to 2.1 (2:1.15.1-0ubuntu2.1) yesterday and now my OpenGL does not work anymore. I have the OpenGL 4.5 drivers installed (340.23.01).
In the Xorg.0.log it says:
[ 10.124] (EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
[ 10.124] (EE) NVIDIA(0): log file that the GLX module has been loaded in your X
[ 10.124] (EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If
[ 10.124] (EE) NVIDIA(0): you continue to encounter problems, Please try
[ 10.124] (EE) NVIDIA(0): reinstalling the NVIDIA driver.
Above that it says:
[ 9.534] (II) LoadModule: “glx”

It says vendor=“X.Org Foundation” when loading the glx module so I guess is that this is causing the error. When looking for all libglx.so-files on my computer, it only shows the one in /usr/lib/xorg/…
So I don’t know if this is really my error since I only have this one libglx.so.
I tried reverting my xserver packages from 2.1 to 2 but the error is still there, I guess something messed up my driver installation.
I have a nvidia-bug-report.log if you need it, but I don’t know how to attach a file here …
Thank you for your help!
