Xnest made my day easy
I was working on a plugin. For testing it, I had to restart GNOME. Damn!! Imagine .. I make a small one line change and to test it it i need to logout and login … No need for that as XNest is here
Xnest lets you start multiple (nested) X-sessions on the same box simultaniously. Easy to use and i comes along with SLED 10.
