The problem there is that vglrun requires that you have a decent graphics
card on the server, which is used to generate the display image for
export to the client display machine. My compute servers don't have any
graphics cards, so this doesn't work. In the future I guess this problem
provides a reason to buy graphics even for a machine that is only a
"compute server", but that doesn't help with existing configurations.
anyhow good to hear that vglrun works with coot
