xorg - not able to run glxdemo from inside lxc container using nvidia - Ask Ubuntu

i have created lxc container of our custom toolchain has many packages. related graphics, have installed nvidia 367.27 driver using nvidia installer inside container(called mk7icontainer)

the nvidia driver libraries/binaries installed @ path /usr/share/nvidia path inside container.

i have installed mesa installed in path /usr inside container.

i compiled glxdemo source code using 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 container, have

display=":0" xauthority=/root/.xauthority 

i starting bash in container using below command:

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

my host machine running ubuntu 16.0.4 , installed same nvidia 367.27 driver using installer. running fine. can run glxdemo on host machine without issues.

however, when try run glxdemo inside container ( compiled using above mentioned command), following error:

x error of failed request:  badvalue (integer parameter out of range 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 idea wrong here?

i want know how read these errors narrow down problem.

source code glxdemo :

i able resolve issue.

i had add nvidia device nodes in lxc container config file.

lxc.cgroup.devices.allow = c 195:* rwm lxc.mount.entry = /dev/nvidia0 dev/nvidia0 none bind,optional,create=file lxc.mount.entry = /dev/nvidiactl dev/nvidiactl none bind,optional,create=file lxc.mount.entry = /dev/nvidia-modeset dev/nvidia-modeset none bind,optional,create=file
