Yeah, I’m an HPC user (and small cluster admin by necessity). Remote X11 windows haven’t really been common for years. Occasionally you’ll see an Rstudio server instance, but this is tunneled through an SSH port forward and uses HTTPS. The last time I needed and X11 remote session in a cluster, it involved Matlab and some kind of toolkit. The performance of using a GUI remotely is nothing compared to just copying a terminal figure through an SSH tunnel and viewing the figure locally. I’d say that the low performance of remote X11 was the biggest factor in this shift.
