Comment 30 for bug 112518

Hi Mke E. I noticed after trying Kubuntu that when one switches user, it opens another "VT" with another X server to that other user. For example, lets say user "Joe" is logged-in usuallyand has locked the screen. Then user "Sarah" arrives and activates the "Switch User" button, then KDM appears as expected. She loges-in to work, and now Joe arrives to continue his work. She lockes the screen, and then Joe just has to push control-alt-F7 to access his locked session, while leaving Sarah's session intact and accessible via control-alt-F9.

In other words, is that possible that this situation is making a confusion here? You do not have Compiz neither Metacity activated, well, do you have Beryl?

I've extensively played with those "Switch user" options, and the only time it really lock-up the computer, leaving it in an unusable state is when "desktop effects" (either by Beryl or Compiz) are activated while switching users.
