The end of October saw the much anticipated release of Ubuntu 8.10 - affectionately called the Intrepid Ibex.
It's a release that sees Ubuntu going from strength to strength.
And with its popularity reaching stratospheric proportions, we thought that now was the perfect time to pool together our favourite tips into one place.
If you've never tried Ubuntu, there's never been a better time to dive in. If you're already a convert, read on to discover how to get the best from your installation.
System performance
1. Shorten the boot menu timeout
If you're fed up of waiting for the boot menu to timeout before your favourite operating system launches, open '/boot/grub/menu.lst' with a text editor and look for the line starting with 'timeout'. Just lower the number to its the right. This is the number of seconds the menu system will wait before booting the default operating system (0 or 1 is not recommended).
2. Monitor boot performance
One of the best utilities you can install for checking your system's performance is called 'bootchart'. After installation and a reboot, 'bootchart' will create a complex graph of everything that's running and taking up resources as your system boots, and place an image of the graph in the /var/log/bootgraph folder.
3. Improve boot speed
When the boot menu appears (you might have to press escape) select the default Ubuntu boot option and press 'e'. Cursor down to the line starting with 'kernel' and press 'e' again. You're now editing the boot parameters, and you need to press space and add the word 'profile'. Press return followed by 'b' to boot. Disk access during your boot sequence will now be profiled, which means that subsequent booting should be faster.
4. Trim unwanted services
The default Ubuntu installation takes an over cautious approach to background services. Bluetooth tools may be be running, for example, even if you don't have the hardware. Disable the services you don't need by opening the Services window from the System>Administration menu. Be careful not to disable services you rely on.
5. Monitor CPU usage
You might think that CPU monitors are purely for geeks trying to steal a few extra cycles from their overclocked processors. But this isn't true. A discreet CPU monitor is the best way detecting a wayward process that's slowing down the rest of the system. Right click on the desktop panel, and select 'System Monitor' for our favourite. There's a similar applet for KDE.
6. Manage your processes
If you do detect a process on your system that's stealing more CPU cycles than it really should, then you need to end that process to get those cycles back. Save all your work, and use the Ubuntu process manager. This is part of the System Monitor tool, and this can be opened from the System>Administration menu.
7. Be nice to one another
If you use the System Monitor to manage your running tasks, you might have noticed the 'nice' column. 'nice' is basically a task's priority, and ranges between -20 to 19. If you have a CPU heavy task running, such as a 3D calculation for example, increasing the nice will lower its priority, and make your system feel more responsive.
The default Gnome desktop
8. Enable Gnome Auto login
A lot of us are the sole users of our computers, and it makes little sense navigating through a login screen before getting to our desktops. You can enable auto-login for a default account on your Ubuntu machine by selecting 'Login Window' from the System> Administration window. Switch to the 'Security' page, enable 'Automatic Login' and select the user.
9. Prune your menus
The more applications you install, the more cumbersome the launch menu becomes. But you can enable the applications you're most likely to use right clicking on Ubuntu icon that hides the menu, and selecting 'Edit Menus'. The application that appears will let you enable or disable menus in the hierarchy.
10. Remove the menu popup delay
HCI gurus insist that there should be a delay between when you click on a menu and when it appears, but if it's speed you're after, you can remove the delay. Open a terminal, and type 'nano ~/.gtkrc-2.0', then add a single line 'gtk-menu-popup-delay = 0'. Save this by pressing escape and typing 'Y', and after a restart you should find your menus are ultra quick.
11. Add More Workspaces
Workspaces are one of the best things about Linux. They're a great way of organising your applications onto different virtual screens. By default, Ubuntu sets up only two, but you can adjust this number by right clicking on the workspace switcher in the bottom right corner of the display and opening the Preferences window.
12. Use Workspaces more effectively
Use 'Ctrl alt' and either cursor left or right to switch between adjacent workspaces, and if you hold down the shift key, the active window will move to the new desktop too. For better control, right click on any windows top border to open a context menu, and from here you can choose to move the window to another workspace.
13. Don't start everything
As with system services, the average Ubuntu installation runs lots of different programs at startup. You can remove those you don't need by launching the Sessions window from the Preferences menu. If you don't use the desktop search, for instance, disable 'Tracker'. Other likely candidates for removal include Bluetooth, the Evolution Alarm Notifier and the Print Queue Applet.
14. Remember the running session
Another neat feature of the setting manager is that you can configure your desktop to remember the applications that were running when you shutdown your machine. This is a great way of quickly launching into your working environment. Just switch to the Session Options page and enable the 'Automatically Remember' option.
15. Fine tune the Gnome desktop
Application shortcuts are hidden behind the Gnome equivalent of the Windows registry editor. This can be launched from the command-line by typing 'gconf-editor'. But be careful, settings changed here could mess up your desktop. If you do, then the desktop can be restored to its default state by deleting the '.gconf' and '.gconfd' folders from your home directory.
16. Launching applications with a key combination
One of the settings hidden in Gconf is the ability to launch applications with a key combination. Navigate to 'apps>metacity>key_binding_commands', double click on one of the 'command_' entries and enter the launch command for the application you want to run. To set the key, double click on the same entry in 'apps>metacity> global_keybindings' and press a key. Holding 'Ctrl Shift alt' and that key will now launch the application.
17. Use pervasive searches
Ubuntu comes with an excellent utilities for searching through the contents of files and emails, but it's not enabled by default. Open the Search and Indexing window from the Preferences menu, and enable both indexing and watching. After the index has been created, you can search through your files using the 'Tracker Search Tool' in the 'Applications>Accessories' menu.
18. Switch To A Faster Desktop
Ubuntu uses the Gnome desktop by default. It's a good choice because Gnome is powerful, capable and popular. But it's not streamlined or particularly efficient. A faster alternative is XFCE, the source of Xubuntu, and this can be installed through the Synaptic package manager by searching for the 'xubuntu-desktop' meta-package.
The KDE desktop
19. Switch to an KDE
If neither Gnome or XFCE are helping you be more productive, then try KDE. It's the most configurable of the Linux desktops, and often takes a different slant on browsing and file management. Version 4 has vastly improved the environment, and it can be installed by searching for the 'kubuntu-desktop' in Synaptic.
20. KDE auto-login
If you prefer Kubuntu or the KDE desktop, then you'll need to use a different configuration panel to enable auto-login. Open KDE's System Settings application, and switch to the Advanced page and open the Login Manager. Enter your root password and switch to the convenience page. From here you can choose to enable a user for auto login.
21. Pre-load Konqueror
If you're always launching KDE's file and web browser, you can pre-load several instances of it to speed up launch time. Open the Settings>Configure Konqueror window, and switch to the Performance page. Increase the number of instances from 1 to something like 4 or 5. Each instance takes extra system memory, but each session of Konqueror will now load almost instantly.
22. Use Konqueror shortcuts
Konqueror is a great file and web browser with plenty of shortcuts for the power user. Our favourite is the ability to use shortcuts in the location field to perform online searches. Typing 'wp:linux' will search Wikipedia for Linux, while 'gg:linux' and ggi:linux' will search Google and Google Images.
System-wide
23. Launch OpenOffice.org faster
The default OpenOffice.org configuration errs on the side of caution. There are 100 levels of undo, for example, and reducing this number will reduce the amount of memory it uses. This setting can be found from the Options window by switching to the Memory page. Try reducing the undo steps to 30.
24. Use the quick launch toolbar
In both Gnome and KDE, you can drag applications from the launch menu onto the desktop and onto the toolbar. Clicking on these icons is the quickest way of launching your most used applications, short of holding down a certain key combination.
25. Replace slow applications
One of the best things about open source is that there's always an alternative, and switching to one can vastly improve your system's performance. Try Abiword instead of OpenOffice.org's Writer, Thunar instead of Nautilus and Opera instead of Firefox. All are broadly compatible with their alternatives, and perform faster.
26. Rapid application launch
If you know the name of the application or tool you want to launch, you can quickly start it by pressing Alt and F2. This displays a single command-line prompt in a window, and into this you type your application name. Type 'firefox' and its icon will appear. Pressing enter will launch it.
27. Take a screenshot
Pressing the Print key will take a screenshot and bring up the save file window. Being able to take a screenshot at any moment is incredibly useful, and is great for saving online order details, for example, or just your high score in Crack Attack. Pressing Alt and Print will take a screenshot of the currently active window.
28. Quickly restart the desktop
Occasionally, you may find that your desktop hangs and you can no longer use the keyboard or mouse. Fortunately, the desktop process is entirely independent of the rest of the operating system, and you can reset the desktop by holding down the Ctrl Alt and backspace keys. But you will still lose any unsaved data, so be careful.
29. Jump to a console
Another option if your desktop has crashed is jumping to a command-line console. Pressing Ctrl and alt, followed by F1-F6 will switch the display to one of six different consoles. From here, you can login and try to kill the process causing trouble, before switching back to your desktop by pressing Ctrl Alt and F7.
30. Create a separate Home partition
When you next perform a fresh installation of Ubuntu, choose the manual partition option and create three separate partitions. One needs to be for '/', and should be around 10-20GB, . Another should be for the swap space, and be around the same size as your installed memory. And the final partition is '/home', and will contain all your personal files. When you next install Ubuntu, choose manual again and your Home partition won't be reformatted, keeping all your personal files and configuration options in tact.
31. Tweak your Nvidia settings
After installing the proprietary driver, Nvidia graphics hardware provides exceptional 3D and 2D acceleration for the Linux desktop. You can fine-tune your Nvidia hardware by installing an application called 'nvidia-settings', from which you can edit your monitor settings, enable twin displays and add a drop shadow to the cursor.
32. Track down large unused files
Large and scattered files can start to slow your desktop down, as well as any applications that rely on reading the contents of a directory. The best tool we've found for consolidating and deleting unused files is called Filelight. It uses a pie chart to show where the largest files are located, and you can easily delete directories of junk from the right click menu.
33. Enable vertical sync in Compiz
Compiz, the 3D whizzy desktop effects application, can be either a resource hog or even an acceleration tool. It depends on the power of your graphics hardware. But we've nearly always had better more responsive results on the desktop by enabling the vertical sync option in the general option page of the Compiz settings manager.
34. Don't Compiz
On the other hand, the wonderful effects that Compiz produces can't really be described as functional, although they do provide some improved usability for some. You can free up plenty of resources by disabling the desktop effects from the Visual Effects page of the Preferences>Appearance window.
35. Get packages off a CD or DVD
Even in these times of pervasive internet, you sometimes need to be able to install a package without having an internet connection. Fortunately, the Synaptic package manager can read the contents of an Ubuntu installation CD, and add those packages to the database for installation from the drive. Open the Software Sources window from the Administration menu, switch to the 'Third Party' page and click on the 'Add CD-ROM' button.
36. Boost load speed with Preload
Preload is a tool you can install through the Synaptic package manager. It will run silently in the background, from where it will try to guess which libraries you're likely to use before you use them. It will then load these into memory so that your applications load quicker. The effects seem to be minimal with recent releases of Ubuntu, but it's worth a try.
37. Use a virtual desktop
If you enjoy trying different distributions, but have always been put off by the installation, try Virtual Box from the official Ubuntu repositories. It's easy to use and lets you install a virtual version of almost any Linux installation (and even Windows) right on your desktop, and running at close to native speeds.
38. Boot into text mode
Sometimes, a graphical environment is unnecessary, especially if you use your machine as a server. Which is exactly why there's a version of Ubuntu called the Server edition. By default, Server has no graphical desktop. But in all other ways, it's the same Ubuntu. This makes it perfect as a web or media streaming server.
39. Suspend your system
Why wait for your system to boot when you can resume your session from hibernation. This is quicker than booting, and you can continue where you left off. But it's also dependent on your hardware behaving itself. Just give it a go to see if your hardware supports the feature. Click on the logout button, and if hibernate appears as an option, it should work.
40. Customise your kernel
If you're feeling really brave (and we'd never recommend this for anyone with too little time on their hands), you could build your own kernel. It's not as hard as it sounds and it will enable you to add only the features and hardware you're likely to use. Excellent step by step instructions can be found here: https://help.ubuntu.com/community/Kernel/Compile
The command-line
41. Try it, it's really not that bad
The command-line really is your friend. After opening Terminal from the Applications>Accessories menu (or Konsole in KDE), you can accomplish many common tasks much more effectively than from any desktop GUI. To copy folder, for example, type 'cp -rf source destination', rename a file with 'mv' and edit a text file using a command called 'nano'.
42. Easy command shortcuts
You can press the tab key while using the command-line to automatically complete command names as well as system paths. You can also cursor up through your command history, and use 'Ctrl + r' to search for a command starting with the characters you begin to type.
43. Replace heavy GUI applications with command-line equivalents
There are command-line versions of most desktop applications. You could install and use 'pine' for your email and news, for instance. Or try 'lynx' for web browsing and 'wget' or 'ncftp' for downloading files. 'mc', short for Midnight Commander, is a feature-full file manager, and all of these tools will run on hardly any memory with hardly any CPU requirements.
44. Create an ISO image from a CD or a DVD
You can create an ISO image from optical media, and most attached devices, by using a single command on the terminal. Type 'dd if=/dev/cdrom of=disk.iso bs=1024' to make a raw copy of the data and drop it into the disk.iso file. You may need to unmount the drive first, by typing 'sudo umount /dev/cdrom'.
45. Read an ISO disc image without burning it
If you've downloaded an ISO disc image, and you want to access the files on it without wasting an optical disk, you can create a virtual drive from the image with a single command. Open the terminal from the Accessories menu. Type 'sudo mkdir /mnt/image', followed by 'sudo mount -o loop disk.iso /mnt/image'. You can now browse the disc by pointing a file browser at the '/mnt/image' folder.
46. Use the 'screen' command
After you've got used to the command-line, one of the best commands to learn is called 'screen'. It's the command equivalent to virtual desktops, and it lets you run several sessions at once, as well as suspend and resume a session. Type 'screen' to start, then press 'Ctrl a' followed by 'c' to create a new session. 'Ctrl a' and 'n' or 'p' will switch through the active sessions. 'Ctrl a' and 'd' will detach from the session, while typing 'screen -r' will resume one.
47. Access your Ubuntu machine from anywhere
The best thing about the command-line is that you can use it to access your machine securely from anywhere on the internet. The key to this is something called 'SSH' - the secure shell. Install 'openssh-server' through Synaptic and use a tool called 'putty' on a Windows machine, or 'ssh' on Linux, to access the command-line through your user accounts on your Ubuntu box.
48. Transfer files between computers files quickly and securely
With the open SSH server installed and running, you can quickly and securely transfer files to and from the remote computer using the 'sftp' command. It works just like FTP, and accepts both 'put' and 'get' for file tranfers. If you prefer a GUI, we recommend using Filezilla on Windows, or 'sftp://' as a protocol in KDE.
49. Avoid typing 'sudo'
You might have noticed that for almost every important configuration command you type, you need to precede it with 'sudo' and your password. This can be a real pain if you're typing one sudo command after the other. Avoid this hassle by typing 'sudo bash', this transparently replaces the current shell with a new one, complete with administrator privileges.
50. Create a root account
If you find yourself spending more and more time requiring system administration privileges, you may as well enable the root account. Just type 'sudo passwd root', and enter your password followed by a new one for the root account. You can now type 'su root' to login as root, but you should only use this mode for essential system maintenance.
