.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 tablet
|
|
|
|
|
shell.
|
|
|
|
|
|
|
|
|
|
When weston is started as the first windowing system (i.e. not under X nor
|
|
|
|
|
under another Wayland server), it should be done with the command
|
|
|
|
|
.B weston-launch
|
|
|
|
|
to set up proper privileged access to devices.
|
|
|
|
|
|
|
|
|
|
Weston also supports X clients via
|
|
|
|
|
.BR XWayland ", see below."

.SH BACKENDS
|
|
|
|
|
.TP
|
|
|
|
|
.I drm-backend.so
|
|
|
|
|
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-backend.so
|
|
|
|
|
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-backend.so
|
|
|
|
|
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.

|
|
|
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
|
|
|
|
|
Tablet shell
|
|
|
|
|
Tablet shell is a graphical user interface aimed for tablet-like
|
|
|
|
|
devices, where usually the only input method is a touch screen.
|
|
|
|
|
It does not support freely floating windows or many other desktop
|
|
|
|
|
features, but intends to provide a natural interface on tablets.
|
|
|
|
|
Tablet shell consists of the shell plugin
|
|
|
|
|
.I tablet-shell.so
|
|
|
|
|
and the special client
|
|
|
|
|
.B weston-tablet-shell
|
|
|
|
|
which provides the basic user interface.

|
|

|
|
|
|
.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 " xwayland.so " 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 .

Set the idle timeout to

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, and depending on the shell in use, a screensaver
|
|
|
|
|
may activate, monitors may switch off, and the shell may lock the session.

.SH DIAGNOSTICS
|
|
|
|
|
Weston has a segmentation fault handler, that attempts to restore
|
|
|
|
|
the virtual console or ungrab X before raising
|
|
|
|
|
.BR SIGTRAP .
|
|
|
|
|
If you run
|
|
|
|
|
.BR weston " under " gdb (1)
|
|
|
|
|
from an X11 terminal or a different virtual terminal, and tell gdb
|
|
|
|
|
.IP
|
|
|
|
|
handle SIGSEGV nostop
|
|
|
|
|
.PP
|
|
|
|
|
This will allow weston to switch back to gdb on crash and then
|
|
|
|
|
gdb will catch the crash with SIGTRAP.
