Edited on 2026-01-26 after upgrading to NixOS 25.11 and GNOME 49, which don’t support X11. Wayland is the only option from now on. TL;DR Here I compare Gnome Remote Desktop, RustDesk and x11vnc. I ended up using Gnome Remote Desktop for “Desktop Saring”, but not for “Remote Login” because it doesn’t work without Network Manager, and I don’t use Network Manager. Also, it doesn’t allow logging into the physical desktop (see below).

TL;DR Lesson learned. I need EDID emulation in a KVM if I want to be able to connect to my desktop remotely with e.g. x11vnc or rustdesk or anything really. One without EDID works fine unless I need to to connect to it remotely. And I do! 🙂. So now I’m using a KC-KVM302AS: A 3-Port 2-Monitor HDMI 4K60Hz KVM-Switch with EDID Emulation: Details A KVM allows me to switch my mouse, keyboard, webcam and monitor between my work laptop and my private desktop.

Whats wrong with tmux tmux (and screen before it) are wonderful. They allow me to start a CLI app in a terminal, disconnect from tmux, close the terminal, and reconnect to it again later. Or I can ssh to a remote machine, start tmux and run a critical command without fear of loosing the connection, because I can always ssh in a re-attach if that happens and still see the old “terminal”.
