How do I switch desktop?

[jsun]

• For web browser sessions, simply log out user, and the select the desired desktop to log in again.
• For VNC client sessions, you cannot easily switch desktop. Use browser session to switch to the desired desktop. And it will persist for VNC client sessions later.
• For the newer RDP sessions in Ubuntu 18.04, simply select desired desktop in ~/.xsession file. After making the change, log out and then log in again.
