Hey,

i m using Windows10 as Host and Ubuntu 18.04 as Guestsystem.
If my Windowsscreen is locked and the Monitor change to power save mode, the Ubuntu VM freeze.

Someone has an idea to solve the problem?

Best Regards,
Nils

I'm not too certain how to fix this, but turn off any power settings or monitor 'monitoring' in the Ubuntu guest. Make it so the Ubuntu if installed on a real PC would stay on running forever and never turn off anything.
