GNOME Clipboard Daemon - your clipboard will actually work

Normally, when you copy something in an X application and you close it, the content of the clipboard is lost. This is probably one of the biggest reasons why people keep saying that copy & paste in Linux "doesn't work".

GNOME Clipboard Daemon is a program that keeps the content of your X clipboard in memory, so the clipboard won' get lost even after you close the application you copied from. It's a daemon - it has no GUI. You start it and it'll run in the background and Just Work(tm).Click here for more information, source & binaries.
