I had follow given instruction to create minimal image for Ubuntu 9.10 Karmic.
To test lxlauncher which is based on lxde is very fast and having small footprint netbook launcher. ( LXLauncher is a lightweight GTK+ 2.x based Easy-Mode launcher for subnotebook like EeePC. It is standard-compliant and desktop-independent. It follows freedesktop.org specs, so newly added applications will automatically show up in the launcher, and vice versa for the removed ones. )
To test overall performance first I had install X server and x11vnc ( VNC server to allow remote access to an existing X session ) Only X server was running fast & take only 150 MB RAM. apt-get install xserver-xorg x11vnc xdm xterm For complete lubuntu-desktop which took hardly 500 MB space on Hard Disk. And provide very user friendly GUI, with all application icons in appropriate category.apt-get install lxdm lxde lxlauncher lubuntu-desktop Lxlauncher have 5 ( actually 4 ) application groups/categories. Which is diffrent that main menu groups.
Internet: Arora (web kit based browser) , Firefox, pidgin, sylpheed, transmission, Wicd Network manager, xchat, pyNeighborhood
SMPlayer: Qt Mplayer front-end, with basic features like playing videos, DVDs, and VCDs & more .....
GMPlayer: GTK+ interface for MPlayer The power of MPlayer combined with a friendly interface for your desktop.
Overall LXDE looks more promising than XFCE. In performance and collection of application/package, I am confident about bright future for LXDE on Beagle Board as well as various embedded platform. Specially I can see LXDE, Lubuntu will catch number one choice for Netbook/Notebook/Subnotebook/Tablet/MID (Mobile Internet Device) platform.
