Lxpup is a lightweight distribution with versions based on Slacko by 01micko, and Precise from Barry Kauler. The desktop environment LXDE seems to be a good compromise between lightness, ease and more aesthetically pleasing. It was created by Jejy69.
This derivative is simply easier to use, lightweight, user-friendly, flexible. It will suit the old and the latest computers, thanks to kernel 3.1.10 and 3.2.29 with Precise. It has a base Slackware/Ubuntu, and therefore a large number of packages easily installable via PPM.
The ISO is available on the Lxpup download page.
