10 cool programs/tricks for Ubuntu Karmic Koala (plus 1 for luck)
1. brightside is a program that makes the corners of your screen "hot" so you can do things like activate the screensaver (and, if you've got it set for it, lock the system), mute the volume, etc, just by moving your mouse to a corner. Mac OS X has this functionality, and it's rather cool.
Installing brightside is as simple as opening a Terminal and putting in (remember, pasting into the terminal is CTL-SHIFT-V, and after a "sudo" you're likely to have to enter your password):
Now, it used to be that a menu item would appear in System-->Preferences called "Screen Actions", and this would allow you to modify which corners do what. For some reason, this may not appear in Karmic. You can create a new menu item by going to System-->Preferences-->Main Menu and making a new item in the System-->Preferences menu called "Screen Actions" with the program setting as:
From there, you can adjust things to how you want them.
2. Some have noticed that many screensavers have disappeared from the transition from Jaunty to Karmic. This was probably down to Ubuntu's need for space for other programs. Is the screensaver you loved no longer there? You can get them all back and more with the following tip.
Go to the terminal and put the following in (if you copy it here, remember that pasting into the terminal is CTL-SHIFT-V):
After that, go to System-->Preferences-->Screensaver and you'll see lots more options.
3. System cleaning: you probably know about the following Terminal commands to clear out bits of cruft that appear on your system after you uninstall some programs:
But there is another that clears out other files associated with removed programs. It's:
It will show you what files it wants to remove before you confirm their removal.
4. Font rendering problems in Firefox or Opera? If your fonts look a bit strange, then perhaps it's time to clear the font cache.
Again, this is easily done in the terminal:
Afterward, a restart of your browser should show fonts better, if they weren't already good before.
5. Do you have Adobe AIR installed? No? Do you want to have it installed?
Download it here: http://get.adobe.com/air/
Open a terminal and navigate to the directory you saved it in.
Now first type in:
Then type in:
This should run the installer, letting you follow the normal steps to install. Now you can use Adobe AIR apps.
6. OpenOffice.org actually has a database, sort of like Access, but it's not installed by default on Ubuntu. Also, there is free clipart available, also not installed by default.
If you want them, again, go to a terminal and type in:
Now you've got a fuller office suite.
7. Do you want a music applet something like Windows Media Player's taskbar thing? You can go to a terminal, typing in:
Now that it's installed on your system, you can right-click your taskbar, select "Add to Panel", go down to "Music Applet" and double-click it. It should then appear on your task bar/panel. This can be moved about and locked into place by right-clicking on it, as is normal for items on the task bar/panel.
8. Do you want to give Empathy a go but find it's not as cool as Pidgin? Are you annoyed that it is buried in that "drawer" applet along with Evolution?
First, go to Empathy and, in the program itself, edit Preferences-->Notifications and untick "Use message indicators".
Now, right click on the envelope "drawer" applet that contains both Empathy and Evolution, and remove it from the panel.
Empathy should now appear in your system tray on its own. It gives better notifications this way, acting more like Pidgin, and you can click it directly.
9. Are you interested in having the bible on your computer? Try this in a terminal:
This is a bit odd in that it installs an Arabic bible as default. That's fine if you speak Arabic, but what if you don't? You can remove that bit with the following:
10. Want to mount a saved ISO file as if it were a CD/DVD? Go to a terminal and install:
The program will appear in your System Tools menu. Running it is easy enough. Find your ISO and mount it to "cdrom" if you've got nothing in your drive. It should then appear in Nautilus for viewing and extracting. You can then, when you are done, unmount it using the program.
11. Lots of Linux folks like logic puzzles. There's a cool game with lots of puzzle types that can be installed easily in a terminal:
Great fun! Also, if you are missing Hearts from Windows, try:
These are some of the things I like to do with Ubuntu after I install it. If you have any questions, please ask!
