What is xdiskusage?
xdiskusage is a user-friendly program to show you what is using up all your disk space. It is based on the design of xhttp://alternativeto.net/software/xdu/ written by Phillip C. Dykstra <dykstra at ieee dot org & gt. Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.

Said about xdiskusage as an alternative
Good very lightweight program for linux. No color coding unfortunately (just white rectangles) but still good for determining what's eating up space on a linux server over X11
