Nope, not active.

Needs -display gtk,gl=on for opengl support.

virgl is silently turned off in case opengl support is not available.
Ideally virgl should be OnOffAuto not bool, but I fear changing that
now (and start throwing errors on virgl=on if opengl is not available)
will break stuff ...

take care,
