== Overview ==
The example run-time Linux filesystem image for the CompuLab CM-T43 System-on-Module / Computer-on-Module is based on Debian GNU/Linux Jessie.
The CompuLab Linux package for CM-T43 includes ready to run Linux kernel binary, root filesystem demo image archive, Linux kernel configuration and source code patches.

The default Debian Jessie Linux image includes more than 400 software packages. Among them:

* Core system
* Debian package management system
* X11 Windowing System
* Fluxbox desktop manager
* Netsurf browser
* Samba connectivity suite
* SSH server and client
* ALSA configuration and usage utilities
* Bluetooth 5.0 tools and daemons

The [[CM-T43: Linux: Getting started]] page provides a brief introduction on how to install the run-time Linux image.

== Using Debian Linux on CM-T43 ==

=== Connection and Logging In ===
Use the following username and password to login:

Account with administrative privileges:
<pre>
cm-debian login: root
Password: 111111
</pre>

Regular user account:
<pre>
cm-debian login: user
Password: 111111
</pre>

To login into the Linux system, you may use a serial console (ttyO0) at 115200 bps, or connect through the network.

=== Networking ===
To configure networking, edit {{filename|/etc/network/interfaces}}, {{filename|/etc/resolv.conf}}, {{filename|/etc/hostname}} and {{filename|/etc/hosts}}. For more information about Debian Linux network configuration read [http://www.debian.org/doc/manuals/reference/ch05.en.html Network setup] chapter in the [http://www.debian.org/doc/manuals/reference/index.en.html Debian Reference].

=== X Windows system ===
CompuLab Debian Jessie Linux demo image contains full featured X Windows system with Fluxbox window manager.
Before starting X Windows, connect USB mouse and keyboard to the system.
You can run X Windows by typing {{cmd|startx}}.

=== Fluxbox window manager ===

CM-T43 Debian Linux features installed Fluxbox package - a lightweight window manager for the X Windowing System.

* Fluxbox provides configurable window decorations, a root menu to launch applications and a toolbar that shows the current workspace name, a set of application names and the current time. There is also a workspace menu which allows you to add or remove workspaces. The {{parameter|slit}} can be used to dock small applications, e.g. most of the bbtools can use slit.
* Fluxbox can iconify windows to the toolbar, in addition to adding the window to the Icons submenu of the workspace menu.

Visit [http://fluxbox-wiki.org Fluxbox Wiki] and [http://fluxbox.org/ Official home page] for more details.

=== Software Management ===

Debian Linux image for CM-T43 includes all the information required to use Debian package management utilities. You can use [http://linux.die.net/man/8/apt-get apt-get] and [http://www.wlug.org.nz/dpkg(8) dpkg] out of the box.

=== MMC/SD ===
The support for MMC/SD card on CM-T43 is built into the Linux kernel.
To mount the memory card, monitor ''/proc/partitions'' to see what partitions were detected on the MMC/SD card. For example, suppose MMC/SD partition you'd like to mount is ''mmcblk0p1'' then:
<pre>
mkdir -p /mnt/mmcblk0p1 && mount /dev/mmcblk0p1 /mnt/mmcblk0p1
</pre>

=== Display options ===
CM-T43 evaluation platform has three video output interfaces: LCD, DVI, and LVDS. Default configuration of Debian Linux for CM-T43 uses LCD as primary video output.
