Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

Earlier this week, I installed routine updates to ubuntu on my main work computer. Unfortunately, there's a huge bug in the latest update: switching windows using alt-tab crashes unity. This makes it impossible to open new applications -- or even shut down.

Since alt-tab is a deeply ingrained reflex for me, my computer is basically unusable as long as this continues. The bug has been reported here, but I don't know how long it will take to fix. In the meantime, I still have work to do.

Is there any way to rollback the latest set or two of updates so that I can get on with my life? (Alternatively, if anyone knows of a fix for the core bug, that would be great too.)

If you use "ccsm" to reassign alt-tab to another windows switcher, could it be fine for you? –  desgua Feb 4 '12 at 23:44
A slightly different approach: I've used ccsm to switch from "unity" to "default" (Under preferences > profile). I can now alt-tab between windows without crashing. New problem: I can only run applications from the terminal -- how do I activate a listing of available applications, similar to the Unity sidebar? –  Abe Feb 6 '12 at 14:25
You can launch some panel (like unity-2d-panel) and add florian-diesch.de/software/classicmenu-indicator for example or use launchpad.net/cardapio or AWN or Docky among others ;-) –  desgua Feb 6 '12 at 22:49
This question appears to be abandoned and unanswered, are you still looking for an answer? If this question no longer applies then you can either delete it or answer it yourself if you've solved the problem. Thanks! –  Eric Carvalho Apr 2 '13 at 14:23
