I noticed that on Ubuntu 20.04, a lot of software is made available through snap and it does not even appear in the distribution's "sources".
This is all good, but when you try to run an application that has graphic output and have it connect via remote X11 to your machine, snap seems to be Unable to open X display. Which is strange, because gnumeric (for example) runs as a remote X11 application just fine.
I suspect that this is a configuration problem. Any ideas on how to run a remote X11 application via snap appropriately?
