Ubuntu is pretty snappy out-of-the-box, but there are some ways to take better advantage of your system’s memory and speed up the boot process. Some of these tips can really speed things up, especially on older hardware.
Ubuntu includes its own firewall, known as ufw – short for “uncomplicated firewall.” Ufw is an easier-to-use frontend for the standard Linux iptables commands. You can even control ufw from a graphical interface.
Vi is a powerful text editor included on most Linux systems. Many people swear by vi and find it faster than any other editor once they’ve learned its key bindings. You can even use vi key bindings in Bash.
SSH offers more than just a secure, remote terminal environment. You can use SSH to tunnel your traffic, transfer files, mount remote file systems, and more. These tips and tricks will help you take advantage of your SSH server.
Tiling window managers make your life easier by automatically arranging windows on the screen for you. Xmonad is a minimal one that’s easy to get started with — all you have to do is learn a few keyboard shortcuts.
We’ve written about using GNU Screen to multitask in the Linux terminal in the past. GNU Screen is the granddaddy of these programs, but tmux and dvtm+dtach are other solutions you may prefer.
Whether you want to shrink your Ubuntu partition, enlarge it, or split it up into several partitions, you can’t do this while it’s in use. You’ll need a Ubuntu live CD or USB drive to edit your partitions.
Ubuntu 12.04 doesn’t ship with any screen savers, just a black screen that appears when your system is idle. If you’d rather have screensavers, you can swap gnome-screensaver for XScreenSaver.
If you’ve just updated to Ubuntu 12.04, you may notice an option missing in its system menu. The Hibernate option is now hidden by default, but you can get it back if you prefer to hibernate your system.
Ubuntu’s sound menu contains Rhythmbox by default. Any other media players you install will also appear in the menu, assuming they support the MPRIS2 specification. You can hide media players in the menu or add any application you like.
Ubuntu’s Unity desktop is a change of pace, whether you’re coming from Windows or another Linux distribution with a more traditional interface. Unity has its own way of doing things, including powerful keyboard shortcuts.
GNOME Shell has been criticized for lacking many familiar features found in GNOME 2, but you can add them yourself with extensions. If you’ve installed GNOME Shell and didn’t like it, don’t write it off until you try some extensions.
Ubuntu’s default configuration tools don’t expose a lot of options for customizing your Ubuntu desktop. Ubuntu Tweak fills the gap, exposing a wide variety of settings unavailable in the default interface.
Programs, such as Nautilus or gedit, allow you to browse or view all the files on your system, but they only allow you to change or create new files in your home directory (e.g., /home/lori) and its subfolders.

Give GNOME Shell a spin if you’re looking for a slick, new Linux desktop environment. It’s similar to Unity in some ways, but more flexible in others – GNOME Shell supports extensions, which can add missing features.
The dash on Ubuntu’s Unity desktop allows you to search for applications, files, music, and videos – but you’re not just limited to these. Install custom lenses and scopes to extend the dash with more features.
We all use text editors to take notes, save web addresses, write code, as well as other uses. Every operating system comes with a default, basic text editor, but most of us install our own enhanced text editors to get more features.
Ubuntu 12.04 is upon us. Aside from the usual assortment of bug fixes and updated software, Ubuntu’s Unity desktop environment has been polished and offers new features and more configurability.
The first thing any Linux user does after installing Linux is installing their favorite packages. Ubuntu makes this easy by syncing your installed applications between computers. And terminal users can install their favorite packages with a single command.
Linux’s command-line utilities can do anything, including perform benchmarks – but using a dedicated benchmarking program is a simpler and more foolproof process. These utilities allow you to perform reproducible tests across different systems and configurations.
The Linux terminal has rich multitasking capabilities. You can switch between the virtual consoles already running on your system, use Bash job control to run processes in the background, and take advantage of GNU screen, a terminal “window manager.”
Large capacity, small-sized, affordable USB flash drives provide us with the ability to easily carry around gigs of data in our pockets. Why not take our favorite programs with us as well so we can work on any computer?
