ive used K-ubuntu ( more or less the same as ubuntu ) but the first one used the K-DE desktop environment and the second one used Gohme, i have also used DSLinux ( damn small linux (only 50mb )
also i have used both X-ubuntu and DSLinux on my modded xbox and they work very very well, i currently have Kutuntu -feisty and XP on my home machine, i used my XP machine mainly for my 3D animation projects and linux for everything else
