[lxc-users] not able to run glxdemo from inside lxc container

[manik sheeri]

I have created lxc container of our custom toolchain that has many
packages. Related to graphics, I have installed nvidia 367.27 driver using
the nvidia installer inside this container(called mk7icontainer)

The nvidia driver libraries/binaries are installed at path
/usr/share/nvidia path
inside this container.

I have also installed mesa installed in path /usr inside container.

I compiled the glxdemo source code using the command as:

gcc -g glxdemo.c -Wl,--rpath-link,/usr/share/nvidia/lib
-Wl,-rpath,/usr/share/nvidia/lib \
-Wl,--rpath-link,/usr/share/nvidia/lib/tls
-Wl,-rpath,/usr/share/nvidia/lib/tls \
-Wl,--rpath-link,/usr/share/nvidia/lib/vdpau
-Wl,-rpath,/usr/share/nvidia/lib/vdpau \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules
-Wl,-rpath,/usr/share/nvidia/lib/xorg/modules \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules/drivers
-Wl,-rpath,/usr/share/nvidia/lib/xorg/modules/drivers \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules/extensions
-Wl,-rpath,/usr/share/nvidia/lib/xorg/modules/extensions -lX11 -lGL
-lGLU -lglut -lm -o glxdemo


Inside the container, I have

DISPLAY=":0"
XAUTHORITY=/root/.Xauthority

I am starting the bash in the container using below command:

sudo lxc-attach -n mk7icontainer --clear-env  -- /usr/bin/bash

My host machine is running Ubuntu 16.0.4 and I installed the same nvidia
367.27 driver using its installer. It is running fine. I can even run
glxdemo on host machine without any issues.

However, when I try to run glxdemo inside the container ( compiled using
above mentioned command), I get the following error:

X Error of failed request:  BadValue (integer parameter out of range
for operation)
Major opcode of failed request:  154 (GLX)
Minor opcode of failed request:  3 (X_GLXCreateContext)
Value in failed request:  0x0
Serial number of failed request:  24
Current serial number in output stream:  25

anyone got any idea what is wrong here?
