Is there a more lightweight solution? Like, some ssh frontend? I’d like to help my mom cleaning up her Windows computer because she’s not very tech savvy. I can of course just screen share on some messaging app but it’d save so much time if I could have control.
I’m not going to be reacting to answers advising me to install a Windows esque distro on her computer.
Many solutions exist, rdp clients aren’t exactly rare. I’m personally using xfreerdp for the extensive options: I can connect to a Windows system (at work) and have it be full screen on 2 of my 3 local monitors. It’s fast, reliable and just works honestly.
But what you seem to be looking for is something more like RustDesk or vnc. You want to look at and help with an existing session. If you connect with remote desktop, the local monitor gets locked, so you can only take over, but not show or help. VNC over the open Internet is generally not a great idea for security, but wire guard exists, as does TailScale and/or NetBird which means you don’t need to expose it. So that also works.
