Looking at the attached information I see this.

xserver.errors:
 Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
 No surface to present from.

That indicates a messed-up video driver installation.

Also this.

UnitySupportTest: Error: command ['/usr/lib/nux/unity_support_test', '-p', '-f'] failed with exit code 1: Error: no composite extension

Also indicates a pretty messed-up video driver installation. This is unlikely to be a bug in Unity, since Unity isn't even run because the installed video driver does not support the basic functionality required. The attached screenshot shows Unity is not running.
