  1. Click on GNOME menu's System > Administration > Language Support >
  2. For new installation of Ubuntu, it will inform that some packages are not installed for current Language support, with "Remind Me Later" and "Install Now".
  3. After responding the above message, Check "Bengali; Bangla" in the Supported language box. Then press Apply.
  4. It will start downloading required packages.

  9. Now, login with your username and password.

Mac OS X

Windows

Click, Start > Settings > Control Panel > Regional and Language Options > Languages > Check, "Install files for complex script and right-to-left languages (including Thai)" > Apply.

It will ask for the Windows Installer CD.

Bangla Input Systems / Keyboard

GNU/Linux


GNOME

Following instructions are for GNOME 2.20.x:

Right click on your "GNOME Panel" > Add to Panel > Utilities > Keyboard Indicator > Add > Close.

Now, Right click on the "Keyboard Indicator" on your "GNOME Panel" > Click "Keyboard Preferences" > Layouts > Add > Select "Layouts: Bangladesh" and "Variants: Default" or "Variants: Probhat" > Add > Close.

Selecting "Variants: Default" will install National Keyboard Layout and "Variants: Probhat" will install Probhat Keyboard Layout.

Now you can toggle between Bangla and other installed keyboard layouts in your system.


KDE

Instruction for KDE version 3.5.x:

Click KDE menu > Control Center > Regional & Accessibility > Keyboard Layout

Check the "Enable Keyboard Layouts" check box. Click on "Bangladesh" from the "Available layouts:" section, then Click "Add >>" button in the right pane. Now from the "Layout variant:" drop list, select "Probhat". Press Apply.

In the "Xkb Options" tab, select "Enable xkb options", and then in the "Xkb Options" list below, you can check both alt keys together to change layout. Now when you press both the alt keys together, keyboard layout will be changed and you can type in Bangla. You can also select other options - depending on your needs.


XFCE

Add the "XkbLayout Option" to the /etc/X11/xorg.conf file as root. Here is an example if you want to use English and Bangla keyboard-settings: 

  Section "InputDevice"
  Identifier  "Keyboard0"
  Driver      "kbd"
       Option      "XkbModel" "pc105"
       Option      "XkbLayout" "us,bd(probhat)"
       Option      "XkbOptions" "grp:alt_shift_toggle"
  EndSection

Now restart your X server by pressing CTRL+ALT+Backspace to make the change effective.

Alt+Shift combination switches between the layouts. You may use instead of alt_shift_toggle many other options like ctrl_shift_toggle, shifts_toggle, ctrl_alt_toggle, lwin_toggle, rctrl_toggle etc.

xfce4-xkb-plugin is a handy plugin for Xfce panel for graphical representation of the selected layout and allows to change it with mouse or other pointing device.
