But between systems this matters none. You will use the same KDE Connect or whatever software of your choice, no matter what the windowing service on each system is.
Not in the thread i replied to. he said how to, you said why ask, i replied because it can be a problem. This is why linux forums get a bad name, instead of replying to the guy with a solution such as KDE, you instead goad them with why ask.
The top reply had a solution. I had a question, seemed irrelevant information, so i asked why it was included and gave him a bit of a hard time. Not like I'm trying to make him angry or something lol
