.TH XWAYLAND 1 "xorg-server 24.1.4" "X Version 11"
.SH NAME
Xwayland \- an X server for running X clients under Wayland.
.SH SYNOPSIS
.B Xwayland
[option ...]
.SH DESCRIPTION
.I Xwayland
is an X server and a Wayland client. It plays the role of a proxy between
legacy X clients which do not support the Wayland protocols and the Wayland
server.
.PP
Usually, \fIXwayland\fP is spawned automatically by the Wayland server
and runs rootless so that X clients integrate seamlessly with the rest
of the Wayland desktop. It is however possible for a user to launch Xwayland
non-rootless, mainly for testing purposes.
.PP
Like all of the X servers, \fIXwayland\fP accepts the command line options
described in the \fIXserver\fP(7) manual page.
The following additional arguments are supported as well.
.TP 8
.B \-decorate
Add decorations to the Xwayland root window when running rootful.

This option has no effect when \fIXwayland\fP is built without libdecor
support (optional).

This option is not compatible with rootless mode (\fI-rootless\fP).
.TP 8
.B \-enable-ei-portal
Enable support for the XDG portal for input emulation.

A Wayland compositor running nested should not use that command line
option with Xwayland.

This option has no effect if the compositor doesn't support the relevant
XDG portal or if Xwayland was not compiled with EI and OEFFIS support.
.TP 8
.B \-fullscreen
Set the Xwayland window fullscreen when running rootful.

This option is not compatible with rootless mode (\fI-rootless\fP).
.TP 8
.B \-geometry \fIWxH\fP
Sets the geometry of the \fIXwayland\fP window to \fIWxH\fP when running rootful.

This option is not compatible with rootless mode (\fI-rootless\fP).
.TP 8
.B \-glamor " [\fIgl|es|off\fP]"
Use given rendering API for Glamor acceleration. Possible options are \fIgl\fP and \fIes\fP.
If \fIXwayland\fP was compiled with Glamor support, this option will instruct \fIXwayland\fP
to use only requested API for Glamor. If this set to \fIoff\fP, effect is equal to \fI-shm\fP option.
Without this option and without \fI-shm\fP option, \fIXwayland\fP tries the OpenGL rendering API first,
and fallback to GL ES if GL version is less than 2.1.

This option is not compatible with \fI-shm\fP option.
.TP 8
.B \-hidpi
Adjust to the scale of the outputs when running rootful in windowing mode.

This option is not compatible with rootless mode (\fI-rootless\fP).
.TP 8
.B \-host-grab
Disable host keyboard shorcuts and confine the pointer when running rootful.

This feature relies on the protocol for inhibiting the compositor keyboard
shortcuts and on the protocol for pointer locking and confinement and may
have no effect if the Wayland compositor in use does not support these
protocols.

Use the keys [CTRL]+[SHIFT] simultaneously to release the keyboard and
pointer devices.

This option is not compatible with rootless mode (\fI-rootless\fP).
.TP 8
.B \-initfd \fIfd\fP
Add the given \fIfd\fP as a listen socket for initialization of X clients.
This options is aimed at \fIWayland\fP servers which run \fIXwayland\fP
on-demand, to be able to spawn specific X clients which need to complete
before other regular X clients can connect to \fIXwayland\fP, like \fIxrdb\fP.
.TP 8
.B \-listen \fIfd\fP
deprecated, use \fI\-listenfd\fP instead.
.TP 8
.B \-listenfd \fIfd\\fP
Add given fd as a listen socket. This option is used by the \fIWayland\fP
server to pass \fIXwayland\fP the socket where X clients connect.
.TP 8
.B \-noTouchPointerEmulation
Disable touch pointer emulation. This allows the Wayland compositor to
implement its own pointer emulation mechanism for X11 clients that don't
support touch input.
.TP 8
.B \-force-xrandr-emulation
Force additional non-native modes to be exposed when viewporter is not
supported by the Wayland compositor.
.TP 8
.B \-nokeymap
Instructs \fIXwayland\fP to ignore the keymap set by the Wayland compositor.

By default, \fIXwayland\fP (as any Wayland client) uses the keymap set by the
Wayland compositor using the standard Wayland protocol.

This option is meant for some specific use cases where it may be desirable to
let the X11 clients control the keymap used in Xwayland, ignoring the keymap
specified by the Wayland compositor.
.B \-output \fIname\fP
Specifies on which output \fIXwayland\fP fullscreen rootful should be placed.
The name must match the name of an existing Wayland output (output names can
be found using wayland-info).

If no matching output can be found, the Wayland compositor will decide on which
output the fullscreen rootful \fIXwayland\fP window will be placed.

This option has no effect if \fIXwayland\fP is not running fullscreen rootful.
.TP 8
.B \-rootless
Run \fIXwayland\fP rootless, so that X clients integrate seamlessly with
Wayland clients in a Wayland desktop. That requires the Wayland server
to be an X window manager as well.
.TP 8
.BI \-shm
Force the shared memory backend instead of glamor (if available) for passing
buffers to the Wayland server.

This option is not compatible with \fI-glamor\fP option.
.TP 8
.BR \-verbose " [\fIn\fP]"
Sets the verbosity level for information printed on stderr.  If the
.I n
value isn't supplied, each occurrence of this option increments the
verbosity level.  When the
.I n
value is supplied, the verbosity level is set to that value.  The default
verbosity level is 0.
.TP 8
.BI \-version
Show the server version and exit.
.TP 8
.B \-wm \fIfd\fP
This option is used by the \fIWayland\fP server to pass \fIXwayland\fP
the socket where the X window manager client connects, when \fIXwayland\fP
is running with \fI-rootless\fP.
.SH ENVIRONMENT
.TP 8
.B WAYLAND_DISPLAY
the name of the display of the Wayland server.
.TP 8
.B XWAYLAND_NO_GLAMOR
disable glamor and DRI3 support in \fIXwayland\fP, for testing purposes.
.SH "SEE ALSO"
