.TH WESTON 1 "2019-03-23" "Weston @version@"
|
|
.SH NAME
|
|
weston \- the reference Wayland server
|
|
.SH SYNOPSIS
|
|
.B weston
|
|
.
|
|
.\" ***************************************************************
|
|
.SH DESCRIPTION
|
|
.B weston
|
|
is the reference implementation of a Wayland server. A Wayland server is a
|
|
display server, a window manager, and a compositor all in one. Weston has
|
|
several backends as loadable modules: it can run on Linux KMS (kernel
|
|
modesetting via DRM), as an X client, or inside another Wayland server
|
|
instance.
|
|
|
|
Weston supports fundamentally different graphical user interface paradigms via
|
|
shell plugins. Two plugins are provided: the desktop shell, and the kiosk
|
|
shell.
|
|
|
|
Weston also supports X clients via
|
|
.BR XWayland ", see below."
|
|
.
|
|
.\" ***************************************************************
|
|
.SH BACKENDS
|
|
.TP
|
|
.I drm
|
|
The DRM backend uses Linux KMS for output and evdev devices for input.
|
|
It supports multiple monitors in a unified desktop with DPMS. See
|
|
.BR weston-drm (7),
|
|
if installed.
|
|
.TP
|
|
.I wayland
|
|
The Wayland backend runs on another Wayland server, a different Weston
|
|
instance, for example. Weston shows up as a single desktop window on
|
|
the parent server.
|
|
.TP
|
|
.I x11
|
|
The X11 backend runs on an X server. Each Weston output becomes an
|
|
X window. This is a cheap way to test multi-monitor support of a
|
|
Wayland shell, desktop, or applications.
|
|
.TP
|
|
.I rdp
|
|
The RDP backend runs in memory without the need of graphical hardware. Access
|
|
to the desktop is done by using the RDP protocol. Each connecting
|
|
client has its own seat making it a cheap way to test multi-seat support. See
|
|
.BR weston-rdp (7),
|
|
if installed.
|
|
.TP
|
|
.I vnc
|
|
The VNC backend runs in memory without the need of graphical hardware. Access
|
|
to the desktop is done by using the RFB protocol. Currently only one
|
|
connecting client is supported. See
|
|
.BR weston-vnc (7),
|
|
if installed.
|
|
.
|
|
.\" ***************************************************************
|
|
.SH SHELLS
|
|
Each of these shells have its own public protocol interface for clients.
|
|
This means that a client must be specifically written for a shell protocol,
|
|
otherwise it will not work.
|
|
.TP
|
|
Desktop shell
|
|
Desktop shell is like a modern X desktop environment, concentrating
|
|
on traditional keyboard and mouse user interfaces and the familiar
|
|
desktop-like window management. Desktop shell consists of the
|
|
shell plugin
|
|
.I desktop-shell.so
|
|
and the special client
|
|
.B weston-desktop-shell
|
|
which provides the wallpaper, panel, and screen locking dialog.
|
|
.TP
|
|
Fullscreen shell
|
|
Fullscreen shell is intended for a client that needs to take over
|
|
whole outputs, often all outputs. This is primarily intended for
|
|
running another compositor on Weston. The other compositor does not
|
|
need to handle any platform-specifics like DRM/KMS or evdev/libinput.
|
|
The shell consists only of the shell plugin
|
|
.IR fullscreen-shell.so .
|
|
.TP
|
|
IVI-shell
|
|
In-vehicle infotainment shell is a special purpose shell that exposes
|
|
a GENIVI Layer Manager compatible API to controller modules, and a very
|
|
simple shell protocol towards clients. IVI-shell starts with loading
|
|
.IR ivi-shell.so ,
|
|
and then a controller module which may launch helper clients.
|
|
.
|
|
.\" ***************************************************************
|
|
.SH XWAYLAND
|
|
XWayland requires a special X.org server to be installed. This X server will
|
|
connect to a Wayland server as a Wayland client, and X clients will connect to
|
|
the X server. XWayland provides backwards compatibility to X applications in a
|
|
Wayland stack.
|
|
|
|
XWayland is activated by instructing
|
|
.BR weston " to load the XWayland module, see " EXAMPLES .
|
|
Weston starts listening on a new X display socket, and exports it in the
|
|
environment variable
|
|
.BR DISPLAY .
|
|
When the first X client connects, Weston launches a special X server as a
|
|
Wayland client to handle the X client and all future X clients.
|
|
|
|
It has also its own X window manager where cursor themes and sizes can be
|
|
chosen using
|
|
.BR XCURSOR_PATH
|
|
and
|
|
.BR XCURSOR_SIZE " environment variables. See " ENVIRONMENT .
|
|

.SH OPTIONS
|
|
.
|
|
.SS Weston core options:
|
|
.TP
|
|
\fB\-\^B\fR\fIbackend\fR, \fB\-\-backend\fR=\fIbackend\fR
|
|
Load
|
|
.I backend
|
|
instead of the default backend, see
|
|
.IR BACKENDS .
|
|
The backend module is searched for in
|
|
.IR "@weston_modules_dir@" .
|
|
The default backend is
|
|
.I @weston_native_backend@
|
|
unless the environment suggests otherwise, see
|
|
.IR DISPLAY " and " WAYLAND_DISPLAY .
|
|
.TP
|
|
\fB\-\^c\fR\fIconfig.ini\fR, \fB\-\-config\fR=\fIconfig.ini\fR
|
|
Load
|
|
.IR config.ini " instead of " weston.ini .
|
|
The argument can also be an absolute path starting with a
|
|
.IR / .
|
|
If the path is not absolute, it will be searched in the normal config
|
|
paths, see
|
|
.BR weston.ini (5).
|
|
If also
|
|
.B --no-config
|
|
is given, no configuration file will be read.
|
|
.TP
|
|
.BR \-\-debug
|
|
Enable debug protocol extension
|
|
.I weston_debug_v1
|
|
which any client can use to receive debugging messages from the compositor.
|
|
|
|
.B WARNING:
|
|
This is risky for two reasons. First, a client may cause a denial-of-service
|
|
blocking the compositor by providing an unsuitable file descriptor, and
|
|
second, the debug messages may expose sensitive information.
|
|
Additionally this will expose weston-screenshooter interface allowing the user
|
|
to take screenshots of the outputs using weston-screenshooter application,
|
|
which can lead to silently leaking the output contents. This option should
|
|
not be used in production.
|
|
.TP
|
|
\fB\-\^l\fIscope1,scope2\fR, \fB\-\-logger-scopes\fR=\fIscope1,scope2\fR
|
|
Specify to which log scopes should subscribe to. When no scopes are supplied,
|
|
the log "log" scope will be subscribed by default. Useful to control which
|
|
streams to write data into the logger and can be helpful in diagnosing early
|
|
start-up code.
|
|
.TP
|
|
\fB\-\^f\fIscope1,scope2\fR, \fB\-\-flight-rec-scopes\fR=\fIscope1,scope2\fR
|
|
Specify to which scopes should subscribe to. Useful to control which streams to
|
|
write data into the flight recorder. Flight recorder has limited space, once
|
|
the flight recorder is full new data will overwrite the old data. Without any
|
|
scopes specified, it subscribes to 'log' and 'drm-backend' scopes. Passing
|
|
an empty value would disable the flight recorder entirely.
|
|
.TP
|
|
.BR \-\-version
|
|
Print the program version.
|
|
.TP
|
|
.BR \-\^h ", " \-\-help
|
|
Print a summary of command line options, and quit.
|
|
.TP
|
|
\fB\-\^i\fR\fIN\fR, \fB\-\-idle\-time\fR=\fIN\fR
|
|
Set the idle timeout to
|
|
.I N
|
|
seconds. The default timeout is 300 seconds. When there has not been any
|
|
user input for the idle timeout, Weston enters an inactive mode. The
|
|
screen fades to black, monitors may switch off, and the shell may lock
|
|
the session.
|
|
A value of 0 effectively disables the timeout.
|
|
.TP
|
|
\fB\-\-log\fR=\fIfile.log\fR
|
|
Append log messages to the file
|
|
.I file.log
|
|
instead of writing them to stderr.
|
|
.TP
|
|
\fB\-\-xwayland\fR
|
|
Ask Weston to load the XWayland module.
|
|
.TP
|
|
\fB\-\-modules\fR=\fImodule1.so,module2.so\fR
|
|
Load the comma-separated list of modules. Only used by the test
|
|
suite. The file is searched for in
|
|
.IR "@weston_modules_dir@" ,
|
|
or you can pass an absolute path.
|
|
.TP
|
|
.BR \-\-no-config
|
|
Do not read
|
|
.I weston.ini
|
|
for the compositor. Avoids e.g. loading compositor modules via the
|
|
configuration file, which is useful for unit tests.
|
|
.TP
|
|
\fB\-\^S\fR\fIname\fR, \fB\-\-socket\fR=\fIname\fR
|
|
Weston will listen in the Wayland socket called
|
|
.IR name .
|
|
Weston will export
|
|
.B WAYLAND_DISPLAY
|
|
with this value in the environment for all child processes to allow them to
|
|
connect to the right server automatically.
|
|
.TP
|
|
\fB\-\-wait-for-debugger\fR
|
|
Raises SIGSTOP before initializing the compositor. This allows the user to
|
|
attach with a debugger and continue execution by sending SIGCONT. This is
|
|
useful for debugging a crash on start-up when it would be inconvenient to
|
|
launch weston directly from a debugger. There is also a
|
|
.IR weston.ini " option to do the same."

.B \-\-scale\fR=\fIN\fR
|
|
Give all outputs a scale factor of
|
|
.I N.
|
|
.TP
|
|
.B \-\-use\-pixman
|
|
Use the pixman renderer. By default, weston will try to use EGL and
|
|
GLES2 for rendering and will fall back to the pixman-based renderer for
|
|
software compositing if EGL cannot be used. Passing this option will force
|
|
weston to use the pixman renderer.
