Description
Xpra is a tool which allows you to run X programs — usually on a remote host — and then direct their display to your local machine, disconnect from these programs, and reconnect from the same or another machine, all without losing any state. It differs from standard X forwarding in that it allows disconnection and reconnection without disrupting the forwarded application; it differs from VNC and similar remote display technologies in that xpra is rootless: i.e., applications forwarded by xpra appear on your desktop as normal windows managed by your window manager, rather than being all "trapped in a box together". Xpra also uses a custom protocol that is self-tuning and relatively latency- insensitive, and thus is usable over network connections that are too slow or unreliable for standard X forwarding.
Installation
To install the xpra package, simply use your favorite package manager. Note that this package only exists in Ubuntu 9.10 or later.
