I left my laptop on for 30 minutes, and when I came back there was an error message.

I clicked on the prompts that asked if I wanted to report the error, but after that I lost my sidebar and header bar. The only buttons left are those in my desktop. I can't do anything now, I can't even log out and shut down properly, unless I press on the power button.

I can open the ones on the desktop but I can't minimize and exit from them. I have tried turning the laptop off and on but the problem is still there. What can I do?

I'm using Ubuntu 14.04 LTS.


You should be able to login into a tty by pressing Ctrl+Alt+F2, and then you can restart Unity by running:

export DISPLAY=:0
unity --replace &

You should then be able to switch back to graphical display with Ctrl+Alt+F7

  • I did what you said, and this is what showed on the screen after I ran the commands: [1] 2323 neo@neo-W251EFQ-W270EFQ:~$ stop: Unknown job: unity-panel-service compiz (core) - Info: Loading plugin: core compiz (core) - Info: Starting plugin: core start: Unkonwn job: unity-panel-service _ it just stops there. what do I do next? – EkisRayos Jun 22 '14 at 14:12
  • You could try safely shutting down with sudo shutdown -h now ( itwon't save any open documents though), and try booting up and logging in again. Unity may be crashing due to a bug - if so it may be a bit difficult to fix. – Wilf Jun 22 '14 at 14:14
