Introduction to LXDE Common

The LXDE Common package provides a set of default configuration for LXDE.



LXDE has no backlight control functionality for laptops. If you need backlight control, you should use an alternative desktop environment, or consider adjusting the backlight on your laptop manually using the instructions from Arch Linux Wiki - Backlight.

This package is known to build and work properly using an LFS 12.0 platform.

Package Information

LXDE Common Dependencies


lxde-icon-theme-0.5.1, LXPanel-0.10.1, LXSession-0.5.5, openbox-3.6.1 (runtime), and PCManFM-1.3.2


Optional Runtime Dependencies

A notification daemon such as notification-daemon-3.20.0 or xfce4-notifyd-0.8.2, and a display manager such as sddm-0.20.0 or lightdm-1.32.0

Installation of LXDE Common

Install LXDE Common by running the following commands:

./configure --prefix=/usr --sysconfdir=/etc &&

This package does not come with a test suite.

Now, as the root user:

make install

If you have installed recommended dependencies, run the following commands as the root user:

update-mime-database /usr/share/mime &&
gtk-update-icon-cache -qf /usr/share/icons/hicolor &&
update-desktop-database -q

Starting LXDE

You can start LXDE from runlevel 3, using xinit-1.4.2, or from runlevel 5, using a Display Manager, such as sddm-0.20.0 or lightdm-1.32.0.

To start LXDE using xinit-1.4.2, run the following commands:

cat > ~/.xinitrc << "EOF"
# No need to run dbus-launch, since it is run by startlxde


The X session starts on the first unused virtual terminal, normally vt7. You can switch to another vtn simultaneously pressing the keys Ctrl-Alt-Fn (n=1, 2, ...). To switch back to the X session, normally started at vt7, use Ctrl-Alt-F7. The vt where the command startx was executed will display many messages, including X starting messages, applications automatically started with the session, and eventually, some warning and error messages. You may prefer to redirect those messages to a log file, which not only will keep the initial vt uncluttered, but can also be used for debug purposes. This can be done starting X with:

startx &> ~/.x-session-errors

When shutting down or rebooting, the shutdown messages appear on the vt where X was running. If you wish to see those messages, simultaneously press keys Alt-F7 (assuming that X was running on vt7).
