One problem I saw was the inability to switch between users without logging out. There was no such option in the menu. Here I saw that the following command brings "Switch User" option in the unlock screen dialog.
sudo ln -s /usr/bin/mdmflexiserver /usr/bin/gdmflexiserver
Now CTRL+L to lock the screen and see the Switch User button. Use it!
- Another alternative is: Menu->System Tools->New Login.
- But it's pretty hidden and I'd prefer the former method.
