[ubuntu] Uninstalled IBus, Lost Much of Desktop Functionality -- How to Restore?

view story

http://ubuntuforums.org – A few minutes ago I uninstalled everything related to IBus that I could find in Synaptic, because I was having trouble getting IBus to allow input of Chinese characters and wanted to re-install it from scratch. Well, that seems to have been a big mistake, as I've completely lost the launcher bar and the system bar (or whatever you call the bar at the top of the screen). I got to a command prompt (by clicking on a document and then hitting Alt-F4 [clicking the close button didn't work] -- the desktop disappeared and I was left with a prompt). I then tried Code: sudo apt-get install ibus (Hardware)
