Are you tired of switching keyboards to go back and forth between your host desktop and your odroid? freenx-server may be of interest to you.

NoMachine [1] provides a commercial product that among many things, provides a fast replacement for VNC. Since the low-level components are GPL'd, they make the source available. The nxserver is not free -- but there is a free GPL'd version: http://freenx.berlios.de/

The nxserver provides a complete desktop from a remote target, just like VNC. You can disconnect from the remote session and re-connect later. The desktop and any running applications stay active.

Reference Wiki

This Wiki: www.taiowiki.com , did all the heavy lifting to provide build instructions for the Raspberry Pi. I built freenx-server from source, using the instructions with a hard-float toolchain specifically for the odroid.

I created a debian binary package on top of my debian-wheezy-gnome-6 release and did clean-machine testing to make sure it would work out-of-the-box.

I only modified sources as mentioned in the Wiki mentioned above.

Dependent Packages

Install some dependent packages first:

sudo apt-get install binutils openssh-server xterm expect tcl8.5


Check your /etc/ssh/sshd_config file. Some may say authorized_keys instead of authorized_keys2. Some may have AuthorizedKeysFile commented out.

AuthorizedKeysFile      authorized_keys2
sudo wget http://http://odroid.us/odroid/users/osterluk/freenx-server/freenx-server-0.7.3-1-armhf.deb
sudo dpkg -i freenx-server-0.7.3-1-armhf.deb

You can find the as-built sources in http://http://odroid.us/odroid/users/osterluk/freenx-server/ in case you need to make changes.

Connect from Host

Use nxclient on your host to connect to the odroid. nxclients are available for Linux and Windows hosts.

There is some issue when trying to connect to ubuntu -- the network connection gets bumped and nxclient gives up...
