Catatan Umum

  1. Ini adalah Panduan Permulaan Tidak Resmi Ubuntu 6.06 (Dapper Drake). Yang tidak diasosiasikan dengan Ubuntu dan Canonical Ltd.
  2. Panduan ini dapat didiskusikan pada Situs Resmi UbuntuGuide.org Forum at ubuntuforums.org. Berhenti sejenak dan bergabunglah dalam diskusi.
  3. Panduan ini diujicoba pada instalasi penuh dari Ubuntu 6.06 x86 Install CD (Dapper Drake)
  4. Jika kamu menjumpai box biru, ini berarti kamu harus mengeksekusi perintah dalam mode Terminal (Applications -> System Tools -> Terminal) atau gunakan content dari box itu seperti yang dijelaskan dalam beberapa instruksi lainnya.
  5. Untuk mengurangi kesalahan ketik, copy dan paste command kedalam Terminal mode (klik knan pada command -> "Copy" atau "Paste". Kamu juga bisa menggunakan Ctrl+C untuk copy dan Shift+Insert untuk pastenya)
  6. "sudo" berarti superuser do. "sudo" akan meminta prompt untuk "Password:". Tolong masukkan password user
  7. Jika kamu menginginkan informasi lebih tentang perintah/command yang ada, mudah saja lihat pada halaman manualnya menggunakan perintah "man". Sebagai contoh, "man sudo" akan menampilkan manual page untuk perintah "sudo".
  8. Jika kamu lelah mengetikkan "apt-get" setiap waktu, Baca #How to apt-get the easy way (Synaptic)
  9. "apt-get" dan "wget" membutuhkan koneksi Internet untuk menginstall/update/download program
  10. Untuk mendownload file, klik kanan pada link -> Pilih "Save Link As..." -> Pastikan nama file dan exstensinya benar
  11. Jika kamu harap untuk membanu menterjemahkan Ubuntu kebahasa asal kamu atau sebaliknya kunjungi https://launchpad.net/
  12. Biarkan semangat "humanity to others" selalu bersama kamu...
Jika kamu menggunakan Kubuntu kamu tidak membutuhkan untuk menginstall Gedit lagi, karena sekarang sudah ada link symbolic dari "gedit" ke "kate", jadi kamu dapat menggunakan semua perintah/command dibawah tanpa ada masalah. Lagi pula, kalau kamu mau menggunakan gedit sebagai editor kamu, lakukan: 
sudo apt-get install gedit
Jika perintah/command "gedit" (symbolic link) tidak bekerja, kamu dapat juga membuatkannya: 
sudo ln -s /usr/bin/kate /usr/bin/gedit
Jika kamu menggunakan versi 64-bit gantikan setiap "i386" dengan "amd64"

# This file is the appropriate place for specifying your customizations to the

# file for you and will cause the daemon and any running GDM GUI programs to
# automatically update with the new configuration.  Not all configuration
# options are supported by gdmsetup, so to modify some values it may be
# necessary to modify this file directly by hand.
# 
# To hand-edit this file, simply add or modify the key=value combination in
# the appropriate section in the template below.  Refer to the comments in the
# gdm.conf file for information about each option.  Also refer to the reference
# documentation.
# 
# If you hand edit a GDM configuration file, you should run the following
# command to get the GDM daemon to notice the change.  Any running GDM GUI
# programs will also be notified to update with the new configuration.
#
# gdmflexiserver --command="UPDATE_CONFIG <configuration key>"
#
# For example, the "Enable" key in the "[debug]" section would be specified by
# "debug/Enable".
#
# You can also run gdm-restart or gdm-safe-restart to cause GDM to restart and
# re-read the new configuration settings.  You can also restart GDM by sending
# a HUP or USR1 signal to the daemon.  HUP behaves like gdm-restart and causes
# any user session started by GDM to exit immediately while USR1 behaves like
# gdm-safe-restart and will wait until all users log out before restarting GDM.
# 
# For full reference documentation see the gnome help browser under
# GNOME|System category.  You can also find the docs in HTML form on

  • Troubleshooting
    • If Xgl/Compiz doesn't seem to work, or you get errors, simply restart your machine after adding "thefuture" to Startup programs
    • If moving windows slows down the system, run gconf-editor from the terminal. Find apps/compiz/general/screen0/options. Disable detect_refresh_rate and set refresh rate to 60. Everything should work fine now...
    • If you are using a non default keyboard layout (other language), you might have to change it back to what you need if the keyboard acts funny at System/Settings/Keyboard.
    • You can also set the Super-key to the windows button here.
    • If you don't want "bottom expanded panel", type "killall gnome-panel" in terminal.

How to install a Wacom tablet

For a detailed guide with screenshots about how to configure the "Extended input devices" in your graphic applications, please follow the official Dapper guide at https://wiki.ubuntu.com//Wacom

With the version of the Linux Wacom driver (0.7.2) in Ubuntu 6.06 Dapper Drake, if you unplug you tablet, it won't function when you plug it back in and you will have to restart X. For this reason, it is best to leave the tablet plugged in. This limitation will be removed when the 0.7.4 version of the driver is included in Ubuntu.

  • 1. Using Synaptic package manager1, check if the packages xserver-xorg-input-wacom and wacom-tools are already installed - if not, install them. If you prefer using the command line, you can also execute : 
     sudo apt-get install xserver-xorg-input-wacom wacom-tools
  • 2. Save a copy of your /etc/X11/xorg.conf : 
      sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
  • then edit it with the command line : 
      sudo gedit /etc/X11/xorg.conf
  • and change all /dev/wacom occurences into /dev/input/wacom (created by wacom-tools udev scripts), then save the file.
  • You should be ready to go after you have restarted X. Remember to configure the "Extended input devices" in your graphic applications (Gimp, Inkscape), however you can already check if it's working by moving your stylus on the tablet : the mouse cursor should go through the whole screen.

How to Configure Ubuntu/Kubuntu with WPA using Network-Manager

Ubuntu Dapper in typical cases can configure WPA to work out of the box with minimal hassle. You'll need to install network-manager.


For Ubuntu: 

sudo apt-get install network-manager-gnome

For Kubuntu (will install knetworkmanager): 

sudo apt-get install network-mananger-kde

Logout/Reboot.

Ubuntu users should now see the NetworkManager Applet in the Gnome notification area. Kubuntu users will probably have to run knetworkmanager before they see NetworkManager in the systray.

Once Network-Manager is installed, click on the NM icon in the notification area (default is at the top right of Ubuntu/Gnome). Choose your network, then enter your passphrase. Type a password for the keyring, and you're set.

If you don't see your network, click "Create New Wireless Network...", type your essid/networkname, then choose "WPA Personal" for wireless security.

  • Note: If you installed Kubuntu then installed ubuntu-desktop & network-manager-gnome, you may not be able to use network-manager in Gnome, if at all. In this case, you may have to use WPA Supplicant and do some manual editing of conf files to get WPA up and running.
  • Note: When you first log into Gnome/KDE, the keyring application will ask for a password. Future revisions of Network-Manager should resolve this.

How to type extended characters

  • Add the keyboard layout US English International (with dead keys)
  • Make US English International (with dead keys) the default keyboard layout.

The key marked ['"] is now a dead key. When you press it, nothing happens. However if you press a consonant immediately afterwards, the consonant appears with an accent.

  • ' + a = á
  • ' + e = é
  • and so on for i-í, o-ó, y-ý, c-ć, z-ź, n-ń, l-ĺ, u-ú, r-ŕ
  • " + 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, ũ, ĩ, 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+u = ú
  • RightAlt+i = í
  • RightAlt+o = ó
  • RightAlt+p = ö
  • RightAlt+[ and ] for « and » respectively.
  • RightAlt+a = á
  • RightAlt+s = ß
  • RightAlt+d = ð
  • RightAlt+l = ø
  • RightAlt+; = ¶
  • RightAlt+: = °
  • RightAlt+z = æ
  • RightAlt+c = ©
  • RightAlt+n = ñ
  • RightAlt+m = µ
  • RightAlt+, = ç
  • RightAlt+/ = ¿
  • RightAlt+1 = ¡
  • 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 = ő (and Ő).
  • RightAlt+#, then a = ā (and Ā). Similarly for ēĒ, ūŪ, īĪ, ōŌ.
  • RightAlt+$ = £
  • RightAlt+% =
  • RightAlt+^ =
  • RightAlt+& =
  • RightAlt+*, then a = ą (and Ą). Similarly for ęĘ, įĮ.
  • RightAlt+(, then a = ă (and Ă)
  • RightAlt+(, then g = ğ (and Ğ)
  • RightAlt+), then a = å (and Å)
  • RightAlt+_ =
  • RightAlt++ = ÷

How to set the Compose key to type special characters

  • Click System, Preferences, Keyboard.
  • Under Layout Options, expand on Compose key position.

Now you can type extended characters using the RightWin key (next to AltGr), according to this keyboard settings file. Specifically, the lines that start with GDK_Multi_key are those that we can use here. The Compose key is actually GDK_Multi_key.

Some examples,

  • RightWin + C + = produces €
  • RightWin + = + C produces €
  • RightWin + C + O produces ©
  • RightWin + O + C produces ©
  • RightWin + a + ' produces á
  • RightWin + a + " produces ä
  • RightWin + a + ` produces à
  • RightWin + a + ~ produces ã
  • RightWin + a + * produces å
  • RightWin + a + ^ produces â
  • RightWin + a + > produces â
  • RightWin + a + , produces ą
  • RightWin + e + - produces ē
  • RightWin + S + 1 produces ¹
  • RightWin + S + 2 produces ²
  • RightWin + S + 3 produces ³

How to limit the user accounts that can connect through ssh remotely

e.g. If you enable the SSH server, then any user with a valid account can connect remotely
This can lead to security risks, as there exist remote password cracking tools that
try common username/password pairs.
  • Keep a backup of the ssh server configuration file with

sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.ORIGINAL

  • Edit the configuration file

sudo gedit /etc/ssh/sshd_config

  • Change the parameter PermitRootLogin from yes to no. The superuser must not be able to connect directly from remote.
  • Add the parameter AllowUsers and specify the usernames (space separated) that can connect remotely.
  • You can also use DenyUsers for fine-grained selection of users.
  • If you enable the openssh server and you have no intention for now to enable remote connections, you may add AllowUsers nosuchuserhere to disable anyone connecting.

Database Server

How to install MYSQL Database Server 

sudo apt-get install mysql-server
  • MySQL initially only allows connections from the localhost (127.0.0.1). We'll need to remove that restriction if you wish to make it accessible to everyone on the internet. Open the file /etc/mysql/my.cnf 
sudo gedit /etc/mysql/my.cnf
  • Find the line bind-address = 127.0.0.1 and comment it out 
...
#bind-address           = 127.0.0.1
...
  • MySQL comes with no root password as default. This is a huge security risk. You'll need to set one. So that the local computer gets root access as well, you'll need to set a password for that too. The local-machine-name is the name of the computer you're working on. For more information see here 
mysqladmin -u root password your-new-password
mysqladmin -h root@local-machine-name -u root password your-new-password
sudo /etc/init.d/mysql restart

  • If you don't have a CD available make SURE you comment/remove the line pertaining to your CD media 
sudo gedit /etc/apt/sources.list

/etc/apt/sources.list

for an upgrade to breezy your sources.list should look something similar to this:

  • Save this file. 
sudo apt-get update

  • Save your session, reboot, and enjoy.
