It is so amazing to discover small distributions which use LXDE. The latest one I became aware of is Masonux:
Masonux is derivative of Ubuntu Linux using the LXDE desktop environment created using remastersys. Masonux contains the following: Ubuntu base install (from the 10 megabyte mini.iso, found here), LXDE, Firefox, Pidgin, Synaptic Package Manager, ubiquity graphical installer, and remastersys.
Last week Lynxis prepared early test ISO images for Lubuntu, the ubuntu flavour of LXDE. Unexpectedly the Lubuntu public download rush crashed the servers of a Berlin creative technology center “c-base” which hosted the test images. Lynxis rents office space there. The download problem was quickly resolved and LXDE/Lubuntu is even more famous now in Berlin. Also another group faced growth troubles. The Lubuntu team which just manages the seed discussed whether to keep the release team open or close the group because that was potentially dangerous. Membership skyrocket to 135 members. It was decided to keep membership open for now. We are also looking for a new logo for Lubuntu as the deadline for the Karmic release cycle quickly approaches.
Sköne Oke 
I only discovered Maxonux relatively recently too. I installed it on my EEE netbook and it’s super-fast. I will probably switch to the official Lubuntu release when it comes out but Maxonux is well worth checking out.
Masonux was easy to install and very fast, but:
1. I manually edited all my partitions and UNchecked the “format” box for my /home partition, but it got formatted anyway. Something in Ubiquity messed up I guess. Not a big deal, but a good reminder to back up stuff first.
2. Masonux didn’t recognize my printer and I never could get it to work.
3. The same sound problem I’ve always had with LXDE – booting up with sound muted by default – persists.
Other than that, I really liked Masonux. It seems like the ORIGINAL Ubuntu/LXDE mixture, Ubuntulite (now U-Lite), will be swallowed up by Lubuntu. There is very little activity in their forums and U-Lite “Jaunty” is still in Alpha. The latest .iso for U-Lite is based on Ubuntu Hardy Heron (8.04), so it looks like the forerunner to all the new LXDE-based Ubuntu variants is on the verge of oblivion. Lubuntu is going to be great, I think.
