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.

Many of the formats used to deliver rich media content are \textbf{proprietary}, meaning they are not free to use, modify and distribute with an open source operating system like Ubuntu. Therefore, Ubuntu does not include the capability to use these formats by default; however, users can easily configure Ubuntu to use these proprietary formats. For more information about the differences between open source and proprietary software, see \chaplink{ch:learning-more}.

If you find yourself in need of a proprietary format, you may install the files necessary for using this format with one command. Before initiating this command, ensure that you have Universe and Restricted repositories enabled. See the \seclink{sec:synaptic} section to learn how to do this.

Once Ubuntu has successfully installed software, your rich media content should work properly.

The Ubuntu configuration utility \textbf{Monitors} allows users to change the resolution. Open it by choosing \menu{System} from the Main Menu, then choosing \menu{Preferences} and then \menu{Monitors}. The resolution can be changed using the drop down list within the program. Picking options higher up on the list (for example, those with larger numbers) will increase the resolution. \screenshot{08-display-properties.png}{ss:display-properties}{You can change your display settings.}

You can experiment with various resolutions by clicking \button{Apply} at the bottom of the window until you find one that's comfortable for you. Typically the highest resolution will be the native resolution. Selecting a resolution and clicking \textbf{Apply} will temporarily change the screen resolution to the selected value. A dialog box will also be displayed. It allows you to revert to the previous resolution setting or keep the new resolution. The dialog box will disappear in 30 seconds, restoring the old resolution. \screenshot{08-display-properties-confirm.png}{ss:08-display-properties-confirm}{You can revert back to your old settings if you need to.} This feature was implemented to prevent someone from being locked out of the computer by a resolution that distorts the monitor and makes it unusable. When you have finished setting the screen resolution, click \textbf{Close}.

Ubuntu occasionally has difficulty running on certain computers, generally when hardware manufacturers use non-standard or proprietary components. The Ubuntu community offers documentation to help you troubleshoot many issues that may arise from this situation, including problems with wireless cards, scanners, mice and printers. You can find the complete hardware troubleshooting guide on Ubuntu's support wiki, accessible at \url{https://wiki.ubuntu.com/HardwareSupport}. If your hardware problems persist, please see \seclink{sec:troubleshooting:getting-more-help} for more troubleshooting options or information on obtaining support or assistance from an Ubuntu user.

Ubuntu is open source software. Simply put, open source software is software whose source code isn't owned exclusively by any one person, group, or organization, but is instead made freely available for download.\marginnote{The \textbf{source code} of a program is the files that have been written to make the program.} This makes Ubuntu different from proprietary software which requires users to purchase licenses before they are able to use the software on their computers.\marginnote{\textbf{Proprietary software} is software that cannot be copied, modified, or distributed freely.} Microsoft Windows and Adobe Photoshop are examples of proprietary software.
