I just tried `ssh -X localadmin@marlin` and it works just as well as 
with -Y.

What would you suggest to compare?

I have some software with X11 GUI I'd like to run inside podman 
containers on machine octopus. The octopus host itself should be as 
minimal and as disposable as practical and only be used as a gateway to 
the software in the containers.  Previously it was enough to have a few 
real metal PCs (like marlin) with a full-blown desktop environment but 
recently the number of OS variants has been increasing and I'd like to 
save resources by using containers instead, where I'm hoping that trying 
& installing new OS distributions and versions would be less hassle and 
costly than dealing with real metal for each combination.

Thanks for your time,
