unity - Menu, launchpad and windows disappeared



On my fresh installed Ubuntu, I ran the things described in this list, more precisely the last part installing a bunch of softwares, when all the unity layout disappeard.



There was:




  • No launchpad


  • No menu bar

  • Windows were only with their bare content

  • alt-tab and other commands of this kind were not responding



In the end I hard-reboot my computer, restarted, and:



It looked like my graphic cards driver was not there anymore (steam saying I only have 250mb of dedicated GPU memory, simple 2D game being suddenly slow) so I assumed something made my graphic driver wrong.
I have a ATI Radeon HD 6800, so I went to AMD's website and installed their last drivers, then rebooted.




Then:




  • At boot, a message (which I don't have the time to see exactly) tells me it desactivated tty (I guess it's a video driver problem?)

  • For a second, the desktop appears correctly, but then everything disappears as said before.

  • I try to access the terminal but can't (tty desactivated). I actually can't do anything else than clicking arround. Right clicking and openning the desktop customization menu works though.

  • Now I can't really do anything, not even access a terminal, so I don't know how to unstuck this...



Ok I just thought of unplugging my second monitor and retry:




This time the system managed to boot and work. I re-replugged my monitor, rebooted again, and had mirror displays and my driver alerting me that I need to configure my displays for higher res.



Went back to the driver, put back my old configuration and all was working like before. I still have to reboot to be sure it stays but, well.



I still have the desactivation of tty at boot though. Any idea how to fix that?
