I was curious. Someone said Kubuntu is awesome. So I installed it (sudo apt-get install kubuntu-desktop).
I didn't like it. Keyboard shortcuts that I became familiar with in Unity weren't working. It just felt too "Kids R Us" for me, like a toy OS, so I logged back into Unity and noticed some oddities. All my menus were jacked. The background of menus are now black and the text IN the menu is a dark grey so I can barely read my menus. A new square icon has appeared in the top panel with a DO-NOT-ENTER icon on it. Upon clicking it gives me ENGLISH, CHARACTER MAP, KEYBOARD LAYOUT, AND TEXT ENTRY SETTINGS.
Google chrome's tabs are now a weird white/grey gradient and my navigation buttons (back, forward, refresh) are a bubbly cartoon-ish blue and green.
So, I ran sudo apt-get purge kubuntu-desktop && sudo apt-get autoremove and rebooted. I still have 3 extra "skin(?)/distros(?)" available to me at the login screen when I click the Ubuntu icon. So looks like not everything got removed.
Any ideas? I really hope I don't have to re-install everything, again. And I learned "unity --reset" has been deprecated :(
