Pekka Paalanen b37ac4006a desktop-shell: remove screensaver support 
This is a follow-up for the patch that removed weston-screensaver. The
aim is to clean up shell.c a little by removing non-essential
components. Vanilla Weston desktop is only a demo, external projects are
encouraged to create user-friendly desktop environments.

The support for launching a screensaver client and the protocol bindings
are removed. With them, all related configuration options are removed,
and the manuals are updated accordingly.

The screensaver protocol definition is left in desktop-shell.xml for
posterity.

This does not affect Weston's or desktop-shells ability to put screens
to sleep after inactivity. The inactivity timer continues to operate as
before. Also screen locking is unaffected.

.SH NAME
weston.ini \- configuration file for
.B Weston
\- the reference Wayland
compositor
.SH INTRODUCTION
.B Weston
obtains configuration from its command line parameters and the configuration
file described here.
.SH DESCRIPTION
.B Weston
uses a configuration file called
.I weston.ini
for its setup.
The
.I weston.ini
configuration file is searched for in one of the following places when the
server is started:
.PP
.RS 4
.nf
.BR "$XDG_CONFIG_HOME/weston.ini " "(if $XDG_CONFIG_HOME is set)"
.BR "$HOME/.config/weston.ini " "(if $HOME is set)"
.B "weston/weston.ini in each"
.BR "\ \ \ \ $XDG_CONFIG_DIR " "(if $XDG_CONFIG_DIRS is set)"
.BR "/etc/xdg/weston/weston.ini " "(if $XDG_CONFIG_DIRS is not set)"
.BR "<current dir>/weston.ini " "(if no variables were set)"
.fi
.RE
.PP
where environment variable
.B $HOME
is the user's home directory, and
.B $XDG_CONFIG_HOME
is the user specific configuration directory, and
.B $XDG_CONFIG_DIRS
is a colon
.B ':'
delimited listed of configuration base directories, such as
.BR /etc/xdg-foo:/etc/xdg .
.PP
The
.I weston.ini
file is composed of a number of sections which may be present in any order, or
omitted to use default configuration values. Each section has the form:
.PP
.RS 4
.nf
.BI [ SectionHeader ]
.RI Key1=Value1
.RI Key2=Value2
...
.fi
.RE
.PP
The spaces are significant.
Comment lines are ignored:
.PP
.RS 4
.nf
.IR "#comment"
.fi
.RE
.PP
The section headers are:
.PP
.RS 4
.nf
.BR "core " "The core modules and options"
.BR "libinput " "Input device configuration"
.BR "shell " "Desktop customization"
.BR "launcher " "Add launcher to the panel"

.BR "terminal " "Terminal application options"
.BR "xwayland " "XWayland options"
.BR "screen-share " "Screen sharing options"
.fi
.RE
.PP
Possible value types are string, signed and unsigned 32-bit
integer, and boolean. Strings must not be quoted, do not support any
escape sequences, and run till the end of the line. Integers can
be given in decimal (e.g. 123), octal (e.g. 0173), and hexadecimal
(e.g. 0x7b) form. Boolean values can be only 'true' or 'false'.
.RE
.SH "CORE SECTION"
The
.B core
section is used to select the startup compositor modules and general options.
.TP 7
.BI "shell=" desktop-shell.so
specifies a shell to load (string). This can be used to load your own
implemented shell or one with Weston as default. Available shells
in the
.IR "__weston_modules_dir__"
directory are:
.PP
.RS 10
.nf
.BR desktop-shell.so

.nf
.BR xwayland.so
.BR cms-colord.so

.BR rpi-backend.so
.BR wayland-backend.so
.BR x11-backend.so
.fi
.RE
.TP 7
.BI "repaint-window=" N
Set the approximate length of the repaint window in milliseconds. The repaint
window is used to control and reduce the output latency for clients. If the
window is longer than the output refresh period, the repaint will be done
immediately when the previous repaint finishes, not processing client requests
in between. If the repaint window is too short, the compositor may miss the
target vertical blank, increasing output latency. The default value is 7
milliseconds. The allowed range is from -10 to 1000 milliseconds. Using a
negative value will force the compositor to always miss the target vblank.
.TP 7
.BI "gbm-format="format
sets the GBM format used for the framebuffer for the GBM backend. Can be
.B xrgb8888,
.B xrgb2101010,
.B rgb565.
By default, xrgb8888 is used.
.RS
.PP
.RE
.TP 7
.BI "idle-time="seconds
sets Weston's idle timeout in seconds. This idle timeout is the time
after which Weston will enter an "inactive" mode and screen will fade to
black. A value of 0 disables the timeout.
.IR Important
: This option may also be set via Weston's '-i' command
line option and will take precedence over the current .ini option. This
means that if both weston.ini and command line define this idle-timeout
time, the one specified in the command-line will be used. On the other
hand, if none of these sets the value, default idle timeout will be
set to 300 seconds.
.RS
.SH "LIBINPUT SECTION"
The
.B libinput
section is used to configure input devices when using the libinput input device
backend.
.PP
Available configuration are:
.TP 7
.BI "enable_tap=" true
enables tap to click on touchpad devices
.RS
.PP
.SH "SHELL SECTION"
The
.B shell
section is used to customize the compositor. Some keys may not be handled by
different shell plugins.
.PP
The entries that can appear in this section are:
.TP 7
.BI "client=" file
sets the path for the shell client to run. If not specified
.I __weston_shell_client__
is launched (string).
.TP 7
.BI "background-image=" file
sets the path for the background image file (string).
.TP 7
.BI "background-type=" tile
determines how the background image is drawn (string). Can be
.BR scale ", " scale-crop " or " tile " (default)."
Scale means scaled to fit the output precisely, not preserving aspect ratio.
Scale-crop preserves aspect ratio, scales the background image just big
enough to cover the output, and centers it. The image ends up cropped from
left and right, or top and bottom, if the aspect ratio does not match the
output. Tile repeats the background image to fill the output.
.TP 7
.BI "background-color=" 0xAARRGGBB
sets the color of the background (unsigned integer). The hexadecimal
digit pairs are in order alpha, red, green, and blue.
.TP 7
.BI "panel-color=" 0xAARRGGBB
sets the color of the panel (unsigned integer). The hexadecimal
digit pairs are in order transparency, red, green, and blue. Examples:
.PP
.RS 10
.nf
.BR "0xffff0000 " "Red"
.BR "0xff00ff00 " "Green"
.BR "0xff0000ff " "Blue"

.B fade,
.B none.
By default, the fade animation is used.
.TP 7
.BI "focus-animation=" dim-layer
sets the effect used with the focused and unfocused windows. Can be
.B dim-layer,
.B none.
By default, no animation is used.
.TP 7
.BI "binding-modifier=" ctrl

surfaces, resizing, rotating, switching, closing and setting the transparency
for windows, controlling the backlight and zooming the desktop. Possible values:
ctrl, alt, super (default)
.TP 7
.BI "num-workspaces=" 6
defines the number of workspaces (unsigned integer). The user can switch
workspaces by using the

.RE
.SH "LAUNCHER SECTION"
There can be multiple launcher sections, one for each launcher.
.TP 7
.BI "icon=" icon
sets the path to icon image (string). Svg images are not currently supported.
.TP 7
.BI "path=" program
sets the path to the program that is run by clicking on this launcher (string).
It is possible to pass arguments and environment variables to the program. For
example:
.nf
.in +4n
path=GDK_BACKEND=wayland gnome-terminal --full-screen
.in
.fi
.PP
.SH "OUTPUT SECTION"
There can be multiple output sections, each corresponding to one output. It is
currently only recognized by the drm and x11 backends.
.TP 7
.BI "name=" name
sets a name for the output (string). The backend uses the name to
identify the output. All X11 output names start with a letter X. All
Wayland output names start with the letters WL. The available
output names for DRM backend are listed in the
.B "weston-launch(1)"
output.
Examples of usage:
.PP
.RS 10
.nf
.BR "LVDS1 " "DRM backend, Laptop internal panel no.1"
.BR "VGA1 " "DRM backend, VGA connector no.1"
.BR "X1 " "X11 backend, X window no.1"

.fi
.RE
.RS
.PP
See
.B "weston-drm(7)"
for more details.
.RE
.TP 7
.BI "mode=" mode
sets the output mode (string). The mode parameter is handled differently
depending on the backend. On the X11 backend, it just sets the WIDTHxHEIGHT of
the weston window.
The DRM backend accepts different modes:
.PP
.RS 10
.nf
.BR "WIDTHxHEIGHT " "Resolution size width and height in pixels"
.BR "preferred " "Uses the preferred mode"
.BR "current " "Uses the current crt controller mode"
.BR "off " "Disables the output"
.fi
.RE
.RS
.PP
Optionally, an user may specify a modeline, such as:
.PP
.nf
.in +4n
.nf
173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

.PP
It consists of the refresh rate in Hz, horizontal and vertical resolution,
options for horizontal and vertical synchronisation. The program
.B "cvt(1)"
can provide suitable modeline string.
.RE
.TP 7
.BI "transform=" normal
The transformation applied to screen output (string). The transform key can
be one of the following 8 strings:
.PP
.RS 10
.nf
.BR "normal " "Normal output."
.BR "90 " "90 degrees clockwise."
.BR "180 " "Upside down."
.BR "270 " "90 degrees counter clockwise."
.BR "flipped " "Horizontally flipped"
.BR "flipped-90 " "Flipped and 90 degrees clockwise"
.BR "flipped-180 " "Flipped upside down"
.BR "flipped-270 " "Flipped and 90 degrees counter clockwise"
.fi
.RE
.TP 7
.BI "scale=" factor
An integer, 1 by default, typically configured as 2 when needed, denoting
the scale factor of the output. Applications that support it render at the
appropriate scale. For other applications, weston will scale their output
by this factor.
.RE
.RS
.PP
Use a value of 2 for outputs with high resolution. Such displays are often
called "HiDPI" or "retina" displays.
.RE
.TP 7
.BI "seat=" name
The logical seat name that that this output should be associated with. If this
is set then the seat's input will be confined to the output that has the seat
set on it. The expectation is that this functionality will be used in a
multiheaded environment with a single compositor for multiple output and input
configurations. The default seat is called "default" and will always be
present. This seat can be constrained like any other.
