I have Ubuntu 14.04 installed (using unity) and everything seems to work fine until I try to use a second user.
Once I click to log into another user it takes me back to the login screen and once it finishes drawing the cursor vanishes. After this point the only way to get it back is to use the arrow keys to reselect the already logged in user and log back in. If I log out of the first user the other user account seems to gets possession of the mouse. Is there some setting to state that the mouse cannot be claimed exclusively by one user? This is most annoying when my Nephew comes over and I have him use the Guest Account to surf the web. It only works if i make sure to sign out of the primary account before I leave for the day. It has does this since I upgrade from 13.10.
Example:
Login screen (has pointer)
Login as Tom (has pointer)
Switch back to Login screen (NO pointer)
Two Possible Use Cases:
4.1. User keyboard to login as Tom (pointer returns)
4.2. User keyboard to login as Jerry (NO pointer)
Same thing happens if you switch users Jerry and Tom from the above example. Whoever logs in first seems to be exclusive rights to the mouse pointer (mouse cursor) and it does not get shared to any user after that.
