Hello Kashyap, I've tried your Docker image again.
I configured my display manager (LightDM, file: /etc/lightdm/lightdm.conf) with xserver-allow-tcp=true. Then I run "xhost +" in a terminal. All demos 1 to 13 worked, but with errors from libGL: libGL error: MESA-LOADER: failed to retrieve device information libGL error: unable to load driver: amdgpu_dri.so libGL error: driver pointer missing libGL error: failed to load driver: amdgpu libGL error: failed to open drm device: No such file or directory libGL error: failed to load driver: radeonsi Demos 12 and 13 are very slow, but I don't know why.
