Bug Description
Binary package hint: fast-user-
Not sure this is the right applet, but it seems to be affecting a number of people.
1) Ubuntu 10.04 LTS (lucid)
2) Unknown (I assumed fast-user-
3) Switching between 2 users repeatedly should work
4) It fails after 1-3 switches with a black/blank screen
Steps to repeat:
- Boot ubuntu and login to user A
- Then Click on power menu (top right corner) and select: Switch from A
- I get the login screen
- I select user B and enter my password
- I hit ok
- I am able to login successfully to user B
- Now, I Click on power menu (top right corner) and select: Switch from B
- I select user A from the login screen and enter my credentials, then hit OK
- I get a black screen
Alternatively:
- Boot ubuntu and login to user A
- Then Click on power menu (top right corner) and select: Switch from A... Select B
- I get the login screen
- I hit ok
- I am able to login successfully to user B
- Now, I Click on power menu (top right corner) and select: Switch from B... Select A
- I get a black screen
In my case, Ctrl+Alt+F1-6 is black as well. The computer is NOT hung, I can type blindly and shut down fine.
