Check If You Are Using X11 or Wayland
If you are using Linux but are not sure which display server you are using (X11; Wayland), you can check your environment variables.
- Wayland uses WAYLAND_DISPLAY.
- X11 uses DISPLAY.
I don't think these variables are mutually exclusive. And it is worth checking for both.
If the WAYLAND_DISPLAY environment variable is present then the system is using Wayland.
I don't believe it is relevant what the values are. We're only interested if the variables are there or not.
In this example, DISPLAY is present. So, I am using X11.
Get-ChildItem Env: | Where-Object { $_.Name -match "(DISPLAY|WAYLAND_DISPLAY)" } Name Value ---- ----- DISPLAY :0.0
You will find other advice online relating to loginctl or $XDG_SESSION_TYPE. But there are problems with those answers. And checking the environment variables above avoids those problems.
