If you have started a session via the dashboard console or NoMachine
back to it later, you get a screen asking for your password.
Apparently, your LinkBlue password won't work there. However, you can
set a local password on your VM. When you log in, you can then use
either the LinkBlue password or your local password. The screen that
won't take your LinkBlue password will, I think, take your local
password. To set up your local password, use ssh
and at the VM command line type
sudo passwd abc123
It will prompt twice for your new password. That sets your local
password. It does not affect your LinkBlue password.
