Linux support is where remote tools quietly stop being equal. A product can be excellent on Windows and barely usable on a Wayland desktop — and you will not discover that until a customer is waiting on the phone.
1. Wayland, not just X11
Most modern desktops run Wayland by default. Screen capture there goes through the portal, which shows the user a picker and asks permission. A tool written for X11 either shows a black screen or quietly falls back to X11 — so test on the distro your customers actually run, not on a VM you configured.
2. Packaging you can install without a fight
- A .deb or .rpm that installs without dragging in a desktop stack.
- An AppImage or static binary for machines you cannot install packages on.
- A clear statement of what it opens on the network, for the person who has to approve it.
3. Consent that a stranger can operate
On a support call the person at the other end is usually not a Linux user. If joining means reading a ten-digit ID, adding a repository and editing a config file, the call is lost. A one-time code and a single Allow prompt is the difference between helping and talking someone through installing.
4. Headless servers are a different problem
For a server with no desktop, a remote desktop tool is the wrong shape entirely — SSH with recorded sessions is the right answer. Decide which of the two you are buying for; tools that claim both usually do one of them badly.
How to test in an afternoon
- Install on a stock Ubuntu with Wayland and on one older X11 machine.
- Have a non-technical colleague join a session from a link, with no prior setup.
- Try a file transfer both ways and check the session recording afterwards.
- Reboot the remote machine mid-session and see what the reconnection asks for.
SimDesk ships a Linux binary and a .deb, uses the desktop portal for capture on Wayland, and joins with a one-time code and an on-screen Allow. It is free to register and use, so the test above costs you an afternoon and nothing else.
