20 Essential Tips Every Ubuntu User Should Know

So you've read our Complete Beginner's Guide to Linux and have decided to adopt an open-source operating system--congratulations! But diving right into a new OS is daunting, even if it is as polished and stable as Ubuntu. That's OK though, because we're here to help. We've compiled a list of the 20 most important skills that every Ubuntu user should have. These tips, ranging from basic GUI manipulation to advanced system recovery, are essential to your Windows-free computing experience. Whether you've just installed Ubuntu for the first time or have been a Linux acolyte for years, you'll want to read our refresher. And if you have any tips you can't live without, we'd love to hear about them in the comments section!

Turn Your Audio Up to 11

The sound dialog menu has been a staple in every version of Ubuntu (and GNOME in general) for many years, but in 9.10 it has received a significant overhaul and no longer resembles a traditional mixer. Previously, the maximum volume of a system was determined by hardware and other factors and could not be easily exceeded on a system-wide level. This was sometimes a problem, since the maximum volume of a system could be well below what the hardware could actually deliver. In 9.10, the volume slider has been modified to boost audio up to roughly 150%, so it is now possible to compensate for any discrepancy. However, you should be careful with this feature—you could potentially damage your speakers if you exceed their limits. (Generally, the volume is too loud if there is distortion.)

Ubuntu 9.10 also features a new ability to choose between several different sound themes for various system events. This feature was present in older versions, but is greatly refined in 9.10.

Create Custom Keyboard Shortcuts

Ubuntu offers extensive keyboard shortcut functionality, including support for some of the keys on multimedia keyboards. These are often detected and appropriately bound out of the box, so there is no need to assign them manually. Keyboard shortcuts are managed through the appropriately named entry in the Preferences sub-menu. To create a new keyboard shortcut combination, scroll down to the desired action in the list and click on the existing combination. When the current entry switches to “new shortcut...” press the new key combination you want to use for that action. To cancel the change, left-click on “new shortcut...”.

Control Your System Remotely with Nautilus

Ubuntu features a powerful file manager called Nautilus that is closely integrated into GNOME. This tool allows you to work with local files in an intuitive interface, but it also has remote-connection capabilities comparable to what can be found in an FTP client. In addition to regular FTP access, it provides a graphical interface for SSH-based remote access to other Linux/Unix systems and support for browsing shared folders on Windows systems on the network.

This functionality is accessed through the “Connect to Server” option in Ubuntu's Places menu. The dialog box allows you to select a protocol, location, user name, (and password, if necessary) and port number. Once you have established a connection, the remote server will be accessible through a folder and can be used and unmounted like any type of storage media.

Customize Your UI with Desktop Compositing

If you have a video card (or even an onboard video chipset) you can turn on various desktop effects with a utility called Compiz Fusion. (We covered Compiz Fusion in depth in a previous article.) Although it is possible to fine-tune the performance of these desktop effects with Compiz-Config Settings Manager (CCSM), Ubuntu also features a built-in interface with several preset functions. This is located on a tab called Visual effects in the Appearance dialog (reached through the Preferences sub-menu under System). There are three preset options: none, normal (a moderate level of effects), and Extra (massive levels of eye candy). If you use CCSM instead, none of the presets will be selected.
