Adding Xfce to your HP Chromebook with crouton
Really easy and it works great!
Geek Note: Long term I’m going to use Crouton to install Xfce which uses the chroot command to run Xfce on top of the Chrome OS, which is already based on Linux. Unlike dual-booting, that means you can switch between Chrome OS and Xubuntu with a quick keyboard shortcut, no reboots necessary.[ Edit 20.08.13: This works great:) ]
crouton: Chromium OS Universal Chroot Environment
crouton is a set of scripts that bundle up into an easy-to-use, Chromium OS-centric chroot generator. Currently Ubuntu and Debian are supported (using debootstrap behind the scenes), but “Chromium OS Debian, Ubuntu, and Probably Other Distros Eventually Chroot Environment” doesn’t acronymize as well (crodupodece is admittedly pretty fun to say, though).
