Yesterday I upgraded from 12.10 to 14.04 by do-release-upgrade.
Things were Ok after the upgrading.

However today when I logged into my account, no menu bar, no unity launch.
I tried ctrl+alt+F1 to open the terminal and re-installed Ubuntu-desktop, but it didn't help.

Then I installed compizconfig-settings-manager. But ccsm failed with the error message could not open display.

The only good news was that when I logged in as guest, the desktop worked fine.

What can I do now?

Updates:

First thank you all.

According to Upgrade from 13.10 to 14.04 no unity dash for default user special compiz config, I deleted ~/.config/dconf/user and ~/.cache/compizconfig-1 and the problem was solved.

I think this was caused by my own configuration files. And definitely bain's method will work too.

I opened TTY because I failed to run terminal by ctrl+alt+T. I didn't realize ccsm couldn't work in that situation.

Thank you once again.

Since it works for guest user but not your normal user, you can fix this by resetting your home directory:

  • Switch to virtual terminal with ctrl-alt-f1
  • Login to your account
  • Do mkdir ~/bak && mv ~/.* ~/* ~/bak
  • Logout
  • Press ctrl-alt-f7 to switch to desktop and log in
  • All of your old files are in ~/bak.
