Public bug reported:

My computer has an Intel i3 processor and no other inbuilt GPU. However,
the nvidia-* latest got installed on the computer during an update
process.

I used sudo apt-get remove nvidia-* to remove all the nvidia related
contents.

Post this event, the unity-desktop has stopped working (in its full
functionality i.e. the sidebar does not appear) and I am now only able
to see the desktop (with the shortcut icons and wallpaper) but not able
to interact with it, nor am I being able to open any applications on it.

What should be done to restore lightdm to its original functionality?

PS: I have already tried the sudo apt-get install --reinstall lightdm
