Wait a moment, what did Alessandro drink tonight?

It is not what it looks, it a serious matter. We have all frozen our Linux environment at least once. I bet most of us, including myself, after trying Ctrl+Alt+Backspace, Ctrl+Alt+F-keys., Ctrl+Alt+Delete, have lost hope and used the power or reset button.
Stop!
That is going to cause a lot of trouble and data loss, possibly unrecoverable.

So what to do?

Here is a tutorial, among dozens you can find if you google:

I hate to ask but why would a system crash cause a loss of a lot of data?

It most definitely can, if you use the power button, especially with certain filesystems.

I was kicking off my old Ubuntu 7.04 when he froze. Worst, I was drunk and I come back to my home late at night. And I start gently my PC and I don't know why, I selected Ubuntu. For a while I was in before my desktop makes wave and I took my foot and I give a little kick on my desktop. Everything froze and I crapt off my installation damn.. Hhaha

thanks for the info
