I just upgraded from Ubuntu 11.10 to 12.04 and when I tried to install Dropbox it froze at 99%. Then I hit the reset button and I lost the control panel on top and the launcher. I then tried Ctrl+Alt+F1 and nothing happened. Any advice?

  • Did you reboot the computer?

  • Attempting to load Dropbox to Ubuntu 12.04 (32bit) will likely lockup Software Centre and/or give you 100% CPU (which could stop you shutting down normally). What happened after you forced a restart?

  • Yes, I did restart the computer, several times. Now I have lost my Home and Computer icons. All I have now is an empty top panel w/o any control buttons. The only thing left is the get Help on line option.I tried using the unity --reset and --reset-icons also.

This is two separate issues.


To force recovery of your GUI, then remove and re-install from text-console mode. This should fully recover, but will not affect any files, folders you have (presumably also backed-up).


Once you re-start your machine, and resolve any issues with 'control panel' and 'launcher' then follow instructions at:
