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_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")
- WLR_RENDERER: forces the creation of a specified renderer (available renderers: gles2, pixman, vulkan)
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
gles2 renderer
- WLR_RENDERER_ALLOW_SOFTWARE: allows the gles2 renderer to use software rendering
Generic
- DISPLAY: if set probe X11 backend in
wlr_backend_autocreate - 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
