HELP! Deleted something that has taken away most of my GUI

[Ghostlove]

I installed Unity to see what it was all about. Then I decided to uninstall it, so I went into Synaptic Package Manager (do you see where this is going?) and removed four (I think) packages that said they were to do with Unity.

Then most of my GUI disappeared. I can only access Firefox because Tweetdeck opens at startup, and I can click links from there for Firefox to open. My desktop background has disappeared, as have my top and bottom menu bar thingies, and the bar at the top of the Firefox window that has the minimise and close buttons.

I don't know if this is relevant but some of my settings have changed too - for example my mouse is now behaving right-handedly when I had it set left-handedly.

I can't do ANYTHING right now except use Firefox. I can't even get back to Tweetdeck because the bar at the bottom with the buttons for each window is gone.

Please, PLEASE will someone help me get it all back? I'd really appreciate any help you can give.

I just got "Unable to locate package gnome-desktop" :/

sudo apt-get install --reinstall gnome-desktop

Right idea, but not quite the right packages. Try:

sudo apt-get install --reinstall ubuntu-desktop gdm xorg

sudo apt-get install --reinstall gnome-desktop

try that but do ubuntu-desktop and not gnome.

sudo apt-get install ubuntu-desktop gdm xorg

All three of those say they are already the latest version. Sorry! Any other ideas?

I updated that to force a reinstall. What you want is to make the package manager check that all their dependencies are installed.

Did I miss something?

Have you tried logging out and at the login screen selecting "Gnome" for the window manager, it should be at the bottom.

There should be safe-mode too.
