Think I have broke my Ubuntu 12.10

[maxalman]

Hi, I have a Dell Inspiron laptop dual booting Windows XP & Ubuntu 12.10. The other day I did a update for Ubuntu 12.10 and after a restart I lost my Unity panel, all I had was my screensaver. I then tried to do a restore using Ubuntu one but I found I couldn't connect to the internet so I checked my network in settings and it showed I was connected to my router. So after doing some research on the internet I tried to reinstall Unity and my internet, anyway it's all gone pear shaped now. After doing a restart all I have now is a black screen with a log in option. After logging in it appears as if I am in a terminal screen/mode, just like when I did Ctrl Alt T gives you, but this time the whole screen is a terminal.
Can anyone help me please this is doing my head in.

Thanks for reading, Alan

I would think that sudo apt-get install --reinstall ubuntu-desktop will get your desktop back. Obviously you will need to be connected to the net but I if you connect to your router using a cable when you start up it should get an address etc and be connected to the net.

Thanks, I will give that a try when I get home from work.

sudo service lightdm start

Same problem here, no problem starting X, I think that what is broke is OpenGL, which got updated yesterday, so Unity (or Gnome Shell) won't start, Gnome classic works OK. Also Ubuntu session doesn't fall back to Unity 2D.

From within a ubuntu session if I try to start Unity I get this output:

I installed Ubuntu 12.10 using a usb stick, can I reinstall Ubuntu 12.10 the same way if nothing else works?

[maxalman]

I would think that sudo apt-get install --reinstall ubuntu-desktop will get your desktop back. Obviously you will need to be connected to the net but I if you connect to your router using a cable when you start up it should get an address etc and be connected to the net.

Tried what you said but it didn't work. can I reinstall Ubuntu the same way I installed it via a usb stick,

(re)installing is a drastic solution, but yes if all else fails is doable.
Here though is the how-to to reset the desktop in version 12.10:
