19131	linux guest os does not recover from host sleep - Win 10 host	eyn		"Since 6.x, Ubuntu 18.04 guest does not recover from host (Win 10) going to sleep for around 30 min. 

If I send the host OS to sleep and immediately (within 5 min), everything is fine.

After a longer sleep, say 20 min, I get varying results:

1) the guest OS seems to have rebooted and I arrive at the login window.  My prior running apps and consoles are gone from the desktop.

2) the OS hangs, showing the login screen.  Mouse and keyboard are not working.  Software reboot (send a shutdown signal) does not work.  Must reboot the guest os. 


My computer is recovering from sleep mode and not hibernate mode.

This seems to have started since 16.x.  I created the guest OS in 15.x.
