I have solved my problem, and will post the steps here. I'm not sure if this should be considered a 'wishlist' item, or if this is just how the operating system is supposed to work -- but it's very frustrating that this option is buried. I've posted the related steps to the Ubuntu forums and hopefully others looking to forward X11 sessions to their Hardy/Intrepid guests will find this information useful.
For those of you struggling with this in Hardy or Intrepid (I'm pretty sure this isn't necessary in Gutsy): The default install of both Hardy and Gutsy are almost completely ready to act as X11 guests (that is, you log into a *nix server from your Ubuntu desktop, run a command, and a GUI program appears on your Ubuntu machine). The only steps needed are: [B]Enable TCP connections to Xserver (only need to do this once) -System > Administration > Login Window -Click the Security tab -Uncheck 'Deny TCP connections to Xserver' -Restart the Ubuntu computer[/B] Enable xauth forwarding (do this only once per Ubuntu session) -Open a terminal -Type 'xhost +' and press Enter Connect to the server (do this for every SSH session, obviously) -Open a terminal -Type 'ssh -X [EMAIL PROTECTED]' and press Enter Hope this saves some frustration! -- Intrepid X11 Forwarding Process Not Obvious to Enable https://bugs.launchpad.net/bugs/290747 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
