Confirmed in Feisty for me. I have had the same problem in Dapper and Edgy.
Sometimes, I can sometimes get around the problem by instead of choosing Switch user do the following: 1. Choose Lock Screen 2. Poke the mouse to get rid of screen-saver 3. Click Switch user 4. Log in as normal for that user. Since this works and the normal switching doesn't, I think it might be something related to the fact that screensaver/locking happens automatically when you switch user and that it might steal the mouse control when the new X server has been started. -- Synaptics touchpad not enabled for second X display https://launchpad.net/bugs/68370 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
