I keep ubuntu up-to-date. I turned on my computer today and It was slow to boot, only reponding after I moved my mouse a bit. Then it got to the screen with an error message but the error message didn't have a title bar/header. There was no taskbar. I couldn't pull up the left bar or open unity from the super key. I couldn't open the terminal from ctrl-alt-t. The only thing I could do was do ctrl-alt-delete. The task manager pulled up in the top left of the screen without a title bar. My CPU usage was erratic and wildly fluctuating. Ram was steady. I noticed a bump in my network usage. What should I do?

What was the error message? – Kaz Wolfe Apr 22 '14 at 17:10

It was just a regular error window that didn't give any information. Ubuntu has experienced an error. [cancel] [report] – user239868 Apr 22 '14 at 17:17

Did you install the drivers for it before this happened? – Kaz Wolfe Apr 22 '14 at 17:25
-
No, I was using the proprietary driver for a while and it was working fine. Even when I used the beta. I reinstalled when 14.04 was released and continued to use the proprietary driver without a problem. – user239868 Apr 22 '14 at 17:28

Does Alt+F2 do anything? Can it open a window? – Kaz Wolfe Apr 22 '14 at 17:32

Alt-F4, after repeated pressing closes the the error windows after I select them by clicking on them. Haven't tried Alt-F2 yet. Currently I'm using windows from my dual boot to post this. – user239868 Apr 22 '14 at 17:35

Try alt+f2 and then compiz --replace – Kaz Wolfe Apr 22 '14 at 17:35

Tried Alt-F2. No response. When I was booting a message came up on the black screen something about kernel. Too fast to catch the whole message. – user239868 Apr 22 '14 at 17:44

It sounds like Compiz (and possibly lightdm) aren't starting properly.
Drop to a TTY and do 'sudo service compiz start' or try 'sudo service lightdm restart'

How? I don't know much about TTY. Okay. found it. http://askubuntu.com/questions/66195/what-is-a-tty-and-how-do-i-access-a-tty – user239868 Apr 22 '14 at 18:07

You can access a TTY by holding ctrl+alt and hitting any of the F1-F6 keys. You will be presented with a full screen terminal (more or less).
To get back to your desktop just hold CTRL+ALT and hit F7.

Tried Ctrl-Alt-F1. it said that compiz was an unrecognized service and "sudo service lightdm restart" brought me back to my desktop nothing got fixed. – user239868 Apr 22 '14 at 18:16

Compiz is finnicky, try something like 'compiz --replace' or 'DISPLAY=:0 compiz --replace' From TTY1 – lbaile200 Apr 22 '14 at 18:17
