Guest OS: Ubuntu 22.04 LTS (upgraded from 20.04, and the same problem was happening with 20.04).It also happens that sometimes my session gets destroyed and gdm restarts asking me to login again, and after that still I can't click or type anything. I am using Ubuntu 22.04 on Virtualbox in a Windows 10 host OS.Įvery now and then the OS freezes and I am unable to click or do anything.
