Installing LXDE to a running system

LXDE requires Debian Lenny (5.0) or later editions to satisfy dependencies to libc6.

aptitude update
aptitude install lxde
virtualbox-guest-utils
Alternatively, if you want a minimal lxde without its recommended applications:

aptitude install --without-recommends lxde-core

Configuring Login Managers
GDM, KDM, LightDM or WDM

No manual configuration is needed. Just select LXDE from the available sessions listed by the display manager. If you don't see LXDE, restart your display manager or reboot.
SLIM

With this display manager, some manual configuration is needed. Please refer to their official document and write your /etc/slim.conf and ~/.xinitrc. The command you should put in your ~/.xinitrc to start LXDE is:

exec startlxde

XDM

XDM reads a file called .xsession in the user's home directory to determine which window manager (resp. desktop environment) to start. As it is usually not present on a fresh Debian installation, we have to create it and put LXDE's startup command there. As an example, this is a minimal working .xsession:

#!/bin/sh
exec startlxde

up, use startx

Run the following command with root access:

update-alternatives --config x-session-manager

Then choose startlxde. (For the option to show-up, you may have to reboot your system first.) The next time you run startx, LXDE will be started.
Configuration for locales and input method

    GDM or KDM: Setting locale is not needed. Input method can be specified by im-switch.
    SLIM: put this in your ~/.xinitrc before "exec startlxde" to set locales.

Lubuntu uses LXDE (Lightweight X11 Desktop Environment) which has built-in an 
application called LXRandR. It creates an autostart script for you.

To update the settings, simply run "lxrandr" in your command-line, 
edit your preferred screen layout and save the result.

export DISPLAY=:0.0

xrandr --output VGA-1 --primary

xrandr --output "$intern" --primary --auto --output "$extern" --right-of "$intern" --auto.

zh_TW.UTF-8 (traditional Chinese, Taiwan) is my locale, please replace it with yours.

export LC_ALL=zh_TW.UTF-8
export LANGUAGE=zh_TW.UTF-8
export LANG=zh_TW.UTF-8

If you need to use input method, add those lines, too. Please refer to the document of your input method. Here I use scim for example. (FIXME: Maybe we can use some im-switch compatible way here. Anyone know how to do it please fix this)

export GTK_IM_MODULE=scim
export QT_IM_MODULE=xim
scim -d
