TeamViewer, or similar.
My mom has been running Linux Mint for 10+ years now. She is not tech savvy, but also not helpless. She has needed help a handful of times, usually with a printer.
Trying to talk anybody through support remotely is a PITA, Linux or Windows. So NAT-triendly remote desktop is very helpful.



I wasn’t aware of RustDesk. I’ve looked for usable solutions in the past and was never saw it or anything else like TeamViewer.
The nature of the problem seems to require a hosted service. So TeamViewer fit the bill and was free for this use case. But I’ll have a look at RustDesk now that I’m aware of it.
All that being said, I don’t mind closed-source. I’m an open-source zealot, but I’m not Richard Stallman. I use Linux at work so I’ll use whatever software gets the job done at the end of the day. I’m just glad to see more software work on Linux.
