What should I do when Ubuntu freezes?

I'm dual-booting Windows 7 and Ubuntu 12.04. When I boot Ubuntu, the interface doesn't respond to my requests. I can launch applications from the unity launcher, but when I try to close them it doesn't respond; even when I try to maximize it does nothing. I tried restarting the GUI, but after a few seconds it happens again. I had the same issue with older versions of Ubuntu and never figured it out.

any info regarding your hardware and driver configuration might help to identify your problem, especially graphics related info. –  Daniel Sep 15 '12 at 17:32

As you probably broke a package related to the operation of the Desktop Environment:

You should install another Desktop Environment for example lubuntu-desktop and after that remove unity and gnome, then reinstall it again, if everything goes ok remove lubuntu (if you want).

To install Lubuntu(LXDE for Ubuntu) (as said on this answer on AskUbuntu) type the following on the command-line:

As you are having problems to use the Desktop Environment, push the following buttons Ctrl + Alt + F1 to go to the tty1 and login again - to come back to the another interface push the following buttons Ctrl + Alt + F7 - after you are logged in tty1 enter with the following line of code:

$ sudo apt-get update && sudo apt-get install lubuntu-desktop

Then remove unity and gnome:

$ sudo apt-get remove unity gnome

After that come back to the graphical interface and reboot the system or type:

$ sudo reboot

Then if everything is ok after booting the system again, reinstall gnome and unity again:

$ apt-get install unity gnome

And reboot the system again.

That's it, I hope I have helped you.

Please explain how removing, installing an alternative, re-installing and removing the alternative would help here. –  gertvdijk Sep 15 '12 at 17:04

But why going through all the hoops , when you can simply reinstall Unity? –  Uri Herrera Sep 15 '12 at 17:27
    
@UriHerrera I think that, by installing lubuntu-desktop(for example) if something happen during the installation process he will still be able to use a graphical interface by choosing it (lubuntu or LXDE) at the start before entering. –  Zignd Sep 15 '12 at 19:01
