When debugging Xwayland-related issues, a common first step in debugging has been to ask the reporter to move their real Xwayland to /usr/bin/Xwayland.bin, and create a shell script starting Xwayland with extra arguments under the original /usr/bin/Xwayland location. Introducing a `WLR_XWAYLAND` environment variable makes this less invasive, by allowing the user to swap out Xwayland without resorting to global system changes (or source patches).

wlroots reads these environment variables
wlroots specific
- WLR_BACKENDS: comma-separated list of backends to use (available backends: libinput, drm, wayland, x11, headless, noop)
- WLR_NO_HARDWARE_CURSORS: set to 1 to use software cursors instead of hardware cursors
- WLR_SESSION: specifies the wlr_session to be used (available sessions: logind/systemd, direct)
- WLR_DIRECT_TTY: specifies the tty to be used (instead of using /dev/tty)
- WLR_XWAYLAND: specifies the path to an Xwayland binary to be used (instead of following shell search semantics for "Xwayland")
DRM backend
- WLR_DRM_DEVICES: specifies the DRM devices (as a colon separated list) instead of auto probing them. The first existing device in this list is considered the primary DRM device.
- WLR_DRM_NO_ATOMIC: set to 1 to use legacy DRM interface instead of atomic mode setting
- WLR_DRM_NO_MODIFIERS: set to 1 to always allocate planes without modifiers, this can fix certain modeset failures because of bandwidth restrictions.
Headless backend
- WLR_HEADLESS_OUTPUTS: when using the headless backend specifies the number of outputs
libinput backend
- WLR_LIBINPUT_NO_DEVICES: set to 1 to not fail without any input devices
Wayland backend
- WLR_WL_OUTPUTS: when using the wayland backend specifies the number of outputs
X11 backend
- WLR_X11_OUTPUTS: when using the X11 backend specifies the number of outputs
Generic
- DISPLAY: if set probe X11 backend in wlr_backend_autocreate
- WAYLAND_DISPLAY, _WAYLAND_DISPLAY, WAYLAND_SOCKET: if set probe Wayland backend in wlr_backend_autocreate
- XCURSOR_PATH: directory where xcursors are located
- XDG_SESSION_ID: if set, session ID used by the logind session
