Linux4One is an Ubuntu based Linux distribution designed for the Acer Aspire One series of netbooks. The standard release uses the GNOME environment, while a lightweight version uses LXDE. CD images are provided, though the use of a Live USB stick for installation is the recommended method.

Linux4One is designed to offer out-of-the-box functionality on machines in the Acer Aspire One series. It incorporates a customised Linux and appropriate drivers to achieve this, as well as a number of tweaks to system files to improve performance.

The distribution is based on Ubuntu 8.04.2 and offers two versions. While the full version can be used on all Aspire One models, the light version is offered to give better performance on machines with fewer resources, particularly the A110.
