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
  • Do you use NVidia or ATI or <insert special video card here> ? – Kaz Wolfe Apr 22 '14 at 17:19
  • AMD ATI E2 VISION – user239868 Apr 22 '14 at 17:23
  • Did you install the drivers for it before this happened? – Kaz Wolfe Apr 22 '14 at 17:25

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. askubuntu.com/questions/66195/… – 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. – lbaile200 Apr 22 '14 at 18:10
  • beat me to it. wait, did you get that from my alt+f2 compiz comment??? – Kaz Wolfe Apr 22 '14 at 18:12
  • 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
