Hello,

On a 10.3-R desktop, I've just upgraded the installed packages
to branches/2017Q1.  Since, I'm unable to run OpenGL related
applications as a vanilla user.  Before, I was running ports close
to branches/2016Q1

I have a Nvidia GeForce GTS 450 (x11/nvidia-driver-304, i.e.,
nvidia-driver-304-304.134).

As root, glxgears runs fine.
As a normal user:

% glxgears
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:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  30
  Current serial number in output stream:  31

I thought about the video group, but I don't have a video group and I
just have /dev/nvidia0 and /dev/nvidiactl, no /dev/dri and such.

Do I have to create the video group and change the group for
/dev/nvidia* (currently, it's wheel)?

For informations:
# glxinfo | head -5
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
