NVIDIA graphics card accessible by one user but not another

I have an OpenSUSE Leap 42.3 workstation with an nVidia graphics card (Quadro K2200) installed. I have installed the latest drivers from the nVidia repository for OpenSUSE, namely the packages:

nvidia-computeG04        
nvidia-gfxG04-kmp-default
nvidia-glG04             
x11-video-nvidiaG04

When executing glxinfo from user1 I receive the proper information regarding the graphics driver:

$ glxinfo | grep -i opengl
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: Quadro K2200/PCIe/SSE2
OpenGL core profile version string: 4.5.0 NVIDIA 390.25
OpenGL core profile shading language version string: 4.50 NVIDIA
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6.0 NVIDIA 390.25
OpenGL shading language version string: 4.60 NVIDIA
OpenGL context flags: (none)
OpenGL profile mask: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 390.25
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

When I execute the same command from user2, I get the following error:

$ glxinfo | grep -i opengl
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  76
  Current serial number in output stream:  77

From what I can gather about library paths, they look identical.

From user1:

$ ldd `which glxinfo`

And user2:

    libXau.so.6 => /usr/lib64/libXau.so.6 (0x00007f7b3ab53000)

The two users both have similar permissions, except for the fact that user1 is in the wheel group, which I set to allow sudo.

For the curious, here is a link to my Xorg log file: https://gist.github.com/cbcoutinho/377dfcf7735c337874919a8e819881ad

Can anyone give me a clue about what may be wrong here?
