Would like to be able to connect to an existing X display, so can access my work environment and everything I left open from home. I vaguely remember something about using x11vnc in the past. But the package does not exists for Fedora 11, so I am thinking there is some built in method now.

NOTE: I connect to my work machine through a VPN so password protection is all I need security wise.


Use x11vnc, It will attach to a running session and let you share the desktop. If you run it as root to connect to an xdm session, you will need to do some research into Xauth as it can be a bit fiddly to set up.

Edit to add: Karl Runge no longer appears to be maintaining the original x11vnc however development is continuing on github. Or you could do as suggested below by @ivan-talalaev and use x0vncserver.

Another advantage of this server is that it supports alot of the advanced VNC features used by UltraVNC including large bitmap caching and file-transfer.

  • okay so x11vnc still the go. So where is the fedora package for it :(

  • Have a look here: rpm.pbone.net/index.php3/stat/3/srodzaj/1/search/x11vnc You might not have much luck though. Fedora 11 is too new. Try installing the Fedora 10 packages.

    it also has a long standing and well documented bug that crashes the server constantly with many standard window functions and the code is orphaned and will likely never be fixed.

    x11vnc is deprecated, use x0vncserver instead (see an other answer)

According documentation Tigervnc has support for this.

x0vncserver is a TigerVNC Server which makes any X display remotely accessible via VNC, TigerVNC or compatible viewers. Unlike Xvnc(1), it does not create a virtual display. Instead, it just shares an existing X server (typically, that one connected to the physical screen).

x0vncserver -display :0

    Just note you will usually need to specify vnc password file too: x0vncserver -display :0 -rfbauth .vnc/passwd

    For the record, Debian provides the package tigervnc-scraping-server for this use-case

If you're using KDE at work, KDE already has a VNC server built in.

Presumably, GNOME does too.


As an alternative, you might want to look at NX. It is usually much faster than VNC over the Internet, and I know you can configure it to be able to access the running X session on the console.


x11vnc (http://www.karlrunge.com/x11vnc/)


Use xrfb.

I did a fairly elaborate setup for a customer site that might be appropriate for you.

This is based on a configuration I did for a customer. They wanted the following:

  • that users could remote-desktop into an already-running desktop running on the system console;
  • that users could initiate a session running on the console if one wasn't already running, and then use that; and
  • that other users could connect to an already-running desktop, sharing access with the user who was already logged in.

See the details here.

Beware the security implications too.
