Gallium is an ideal Linux-to-Chromebook platform because: It is based on Xubuntu, which is already an incredibly lightweight and performance-centric desktop environment. It offers a much faster boot time than other Chromebook-ready Linux distributions. It offers an integrated ChromeOS touchpad driver for better performance/responsiveness.
Aug 28, 2015 · I did the RW_Legacy install, keeping the old ChromeOS for possible use. I installed GalliumOS on a 16GB stubby Sandisk thumb drive. I partitioned for 1GB Boot, 9GB Root, 1GB Swap (likely wasted?), and the rest for Home. After the install, with just Firefox added, my file system shows 4.4GB free, and Home shows 4GB free. GalliumOS runs very well!
