OK - - - long hiatus but I had issues with snapd that needed resolving before I could even try what you had suggested.
Was able to work through to the end of glxgears and that was working. Didn’t bother with audio as I really don’t have my system hooked up for it and am not interested in having it.
What my issue is - - is this:
I am wanting to run a package called geany (its a text editor and a small set of other things rolled together and its sortof gui and not totally cli but cli can be invoked through it and it works in plain text - - - all important features for my purpose!) in this gui container.
This isn’t for me (it is but . . . ) but its so that I can ask someone who knows nothing about linux or kumquats or gizmos to log in - - like this, your password is developed like this (with definition) and then they enter information into a text file which is the purpose for this container.
This is fairly a fairly ‘common’ use for a VM but is this what containers are for?
(maybe even @stgraber would care to comment - - - please?)
Maybe I’m misunderstanding the purposes of containers. If I’m being to forthright or bold in my questions - - - well - - - in business one learns that if you don’t ask you just won’t find out, if you need it - - - ask for it.
