view story

http://forums.fedoraforum.org – Hello, I'm using Fedora 16 & Xfce desktop. There are several drive icons on my desktop. These drives are partitions of other distros/os ; I don't need to see/use them in Fedora. How to hide them? I've uploaded a screenshot of desktop. Thanks. Attached Thumbnails   (HowTos)
