wlroots reads these environment variables
|
|
|
|
# wlroots specific
|
|
|
|
* *WLR_BACKENDS*: comma-separated list of backends to use (available backends:
|
|
libinput, drm, wayland, x11, headless)
|
|
* *WLR_NO_HARDWARE_CURSORS*: set to 1 to use software cursors instead of
|
|
hardware cursors
|
|
* *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)
|
|
* *WLR_RENDER_DRM_DEVICE*: specifies the DRM node to use for
|
|
hardware-accelerated renderers.
|
|
|
|
## 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
