Wait while Ubuntu starts up. You \textit{will not} see a normal login screen. Instead, you will be presented with a terminal prompt that looks something like:

If you've deleted a file by accident, you may be able to recover it from Ubuntu's trash folder. This is a special folder where Ubuntu stores deleted files before they are permanently removed from your computer.

To access the trash folder, select \menu{Places \then Computer} from the top panel, then choose \menu{Trash} from the list of places in the left-hand sidebar of the window that appears (alternatively, click on the trash applet at the far right of the bottom panel). To remove items from this folder and restore them to your computer, right-click on the items you want and select \button{Restore}, or otherwise drag them wherever you would like (we recommend a memorable location, such as your home folder or desktop).

Over time, Ubuntu's software packaging system can accumulate unused packages or temporary files. These temporary files, also called caches, contain package files from all of the packages that you have ever installed. Eventually, this cache can grow quite large. Removing them allows you to reclaim space on your computer's hard drive for storing your documents, music, photographs, or other files.

To clear the cache, you can use either the \code{clean}, or the \code{autoclean} option for a command-line program called \commandlineapp{apt-get}. The \code{clean} command will remove every single cached item, while the \code{autoclean} command only removes cached items that can no longer be downloaded (these items are often unnecessary). To run \code{clean}, open \textbf{Terminal} and type:

Packages can also become unused over time. If a package was installed to assist with running another program \dash and that program was subsequently removed \dash you no longer need the supporting package. You can remove it with \code{autoremove}.
