I accidentally shut down during an update. I rebooted, I immediately did a "sudo apt-get update" and sudo apt-get upgrade. My computer is working, but doing a few weird things. When I boot up, put my password, it shows the screen, but takes Unity an extra 10 seconds to come on. Also, when I move cursor through a drop down menu, it seems to try to re-size each selection or moves the menu in funny sort of way.
Any ideas? Can I re-install the updates.
