General Notes
- This is an Unofficial Ubuntu 5.10 (Breezy Badger) Starter Guide. It is not associated with Ubuntu and Canonical Ltd.
- Guide is tested on a full installation of the Ubuntu 5.10 x86 Install CD (Breezy Badger)
- If you see a bluish box, this means you have to execute the
commands in Terminal mode (Applications -> System Tools ->
Terminal) or use the content of that box as mentioned in some other
instructions.
- To reduce typo mistakes, copy and paste the commands into
Terminal mode (right click on the commands -> "Copy" or "Paste". You
can also use Ctrl+C to copy and Shift+Insert to paste it)
- "sudo" means superuser do. "sudo" will prompt for "Password:". Please specify user password
- If you want more information about any command, simply look at
the manual page for it using the "man" command. For example, "man sudo"
will display the manual page for the "sudo" command.
- If you are tired of typing "apt-get" all the time, Read #How to apt-get the easy way (Synaptic)
- "apt-get" and "wget" requires Internet connection to install/update/download programs
- To download file, right click on the link -> Select "Save Link As..." -> Make sure file name and extension are correct
- If you wish to help translating Ubuntu to your native language or to help Ubuntu otherwise visit https://launchpad.net/
- May the "humanity to others" spirit be with you always...
- If you are using Kubuntu you need to install Gedit
sudo apt-get install gedit
- Or replace 'gedit' with 'kwrite', for example, instead of writing
sudo gedit /etc/apt/sources.list
- Write
sudo kwrite /etc/apt/sources.list
- If you are using 64-bit version replace "i386" with "amd64"

The key marked ['"] is now a dead key. When you press it, nothing

consonant appears with an accent.
 | ' + a = á
|
 | ' + e = é
|
 | and so on for i-í, o-ó, y-ý, c-c', z-z', n-n', l-l', u-ú, r-r'
|
 | " + a = ä
|
 | " + e = ë
|
 | and so on for y-ÿ, u-ü, i-ï, o-ö
|
Similarly, ` and a consonant generates à, è, ù, ì, ò.
Similarly, ~ and a consonant generates ã, u~, i~, õ, ñ.
To type ' and ", press RightAlt+' and RightAlt+" respectively.
To type ' and ", you may also press '+<space> and "+<space> respectively.
There are more characters available by keeping RightAlt pressed and typing a character. Therefore,
 | RightAlt+q = ä
|
 | RightAlt+w = å
|
 | RightAlt+e = é
|
 | RightAlt+r = ®
|
 | RightAlt+t = þ
|
 | RightAlt+y = ü

|

|
 | RightAlt+p = ö
|
 | RightAlt+[ and ] for « and » respectively.
|
 | RightAlt+a = á
|
 | RightAlt+s = ß
|
 | RightAlt+d = ð

 | RightAlt+2 = ²
|
 | RightAlt+3 = ³
|
 | RightAlt+4 = ¤
|
 | RightAlt+5 = €
|
 | RightAlt+6 = ¼
|
 | RightAlt+7 = ½
|
 | RightAlt+8 = ¾
|
 | RightAlt+9 = ‘
|
 | RightAlt+0 = ’
|
 | RightAlt+- = ¥
|
 | RightAlt+= = ×
|
 | RightAlt+! = ¹
|
 | RightAlt+@, then o = o" (and O").
|
 | RightAlt+#, then a = a- (and A-). Similarly for e-E-, u-U-, i-I-, o-O-.
|
 | RightAlt+$ = £
|
 | RightAlt+% =

 | RightAlt+^ =
|
 | RightAlt+& =
