Title:
  Getting a black/blank screen when switching between users in lucid

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: fast-user-switch-applet

  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-switch-applet, but I can't find a version number for it, so maybe this isn't part of Lucid?)
  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.
