Hi Martin, Xvfb is a fake display, the fact that your xclock is appearing on the virtual framebuffer rather than over your tunneled SSH connection suggests that $DISPLAY is being overwritten after you log in, or ssh is incorrectly choosing a display ID that is identical to the ID that Xvfb is using. I can't say much about NX, unfortunately, since I have never used it. --nate > > Should I expect that either tunneling or NX works ‘out of the box’, or are > there more packages I need to install and configure?
