It means the opengl driver does not support the needed context.
For example by default the LazOpenGLContext wants 8bit red, green,
blue and 24bit depth bits.

Ask to run in a terminal:
glxinfo

This gives the supported visuals.
Maybe he runs the program in a virtual machine with limited 3D support.
