screen-share Screen sharing optionsPossible 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’.
CORE SECTION
The core section is used to select the startup compositor modules and general options
**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 /usr/lib/x86_64-linux-gnu/weston directory are:
desktop-shell.so**modules=**xwayland.so,cms-colord.so
specifies the modules to load (string). Available modules in the /usr/lib/x86_64-linux-gnu/weston directory are:
xwayland.so cms-colord.so screen-share.so
backend= headless-backend.so
overrides defaults backend. Available backend modules in the /usr/lib/x86_64-linux-gnu/weston directory are:
drm-backend.so
fbdev-backend.so
headless-backend.so
rdp-backend.so
rpi-backend.so
wayland-backend.so
x11-backend.sorepaint-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.
gbm-format=format
sets the GBM format used for the framebuffer for the GBM backend. Can be xrgb8888, xrgb2101010 ,rgb565 By default, xrgb8888 is used.
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.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.
LIBINPUT SECTION
The libinput section is used to configure input devices when using the libinput input device backend.
Available configuration are:
enable_tap= true
enables tap to click on touchpad devices
SHELL SECTION
The shell section is used to customize the compositor. Some keys may not be handled by different shell plugins.
The entries that can appear in this section are:
**client=**file
sets the path for the shell client to run. If not specified weston-desktop-shell is launched (string).
**background-image=**file
sets the path for the background image file (string).
配置背景图片的路径
background-image=/usr/share/weston/background.png 不配置则使用/usr/share/weston/pattern.png
**background-type=**tile
determines how the background image is drawn (string). Can be 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.
缩放(scale)意味着缩放以精确拟合输出，而不是保留纵横比。 缩放裁剪( scale-crop)保留纵横比，将背景图像缩放到足以覆盖输出的大小，并使其居中。如果宽高比与输出不匹配，则图像最终从左右和顶部和底部裁剪。 平铺(tile)重复背景图像以填充输出.**background-color=**0xAARRGGBB
sets the color of the background (unsigned integer). The hexadecimal digit pairs are in order alpha, red, green, and blue.
设置background颜色**clock-format=**format
sets the panel clock format (string). Can be none, minutes, seconds. By default, minutes format is used.
panel上显示时钟格式none, minutes, seconds**panel-color=**0xAARRGGBB
sets the color of the panel (unsigned integer). The hexadecimal digit pairs are in order transparency, red, green, and blue. Examples:
设置panel颜色
0xffff0000 Red
0xff00ff00 Green
0xff0000ff Blue
0x00ffffff Fully transparent**panel-location=**top
sets the location of the panel (string). Can be top, none.
top:顶部显示panel(横条), none:不显示横条
**locking=**true
enables screen locking (boolean).
**animation=**zoom
sets the effect used for opening new windows (string). Can be zoom, fade, none. By default, no animation is used.
打开一个新窗口的动画效果
zoom:放大 fade:淡出
**close-animation=**fade
sets the effect used when closing windows (string). Can be fade, none. By default, the fade animation is used.
关闭窗口的动画效果
**startup-animation=**fade
sets the effect used for opening new windows (string). Can be fade, none. By default, the fade animation is used.
**focus-animation=**dim-layer
sets the effect used with the focused and unfocused windows. Can be dim-layer, none. By default, no animation is used.
**allow-zap=**true
whether the shell should quit when the Ctrl-Alt-Backspace key combination is pressed
**binding-modifier=**ctrl
sets the modifier key used for common bindings (string), such as moving surfaces, resizing, rotating, switching, closing and setting the transparency for windows, controlling the backlight and zooming the desktop. Possible values: none, ctrl, alt, super (default)
**num-workspaces=**6
defines the number of workspaces (unsigned integer). The user can switch workspaces by using the binding+F1, F2 keys. If this key is not set, fall back to one workspace.
**cursor-theme=**theme
sets the cursor theme (string).
**cursor-size=**24
sets the cursor size (unsigned integer).
**lockscreen-icon=**path
sets the path to lock screen icon image (string). (tablet shell only)
**lockscreen=**path
sets the path to lock screen background image (string). (tablet shell only)
**homescreen=**path
sets the path to home screen background image (string). (tablet shell only)
LAUNCHER SECTION
**icon=**icon
sets the path to icon image (string). Svg images are not currently supported.
**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:
path=GDK_BACKEND=wayland gnome-terminal --full-screen
OUTPUT SECTION
**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 weston-launch(1) output. Examples of usage:
LVDS1 DRM backend, Laptop internal panel no.1
VGA1 DRM backend, VGA connector no.1
X1 X11 backend, X window no.1
WL1 Wayland backend, Wayland window no.1
See weston-drm(7) for more details.
**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:
WIDTHxHEIGHT Resolution size width and height in pixels preferred Uses the preferred mode current Uses the current crt controller mode off Disables the output
Optionally, an user may specify a modeline, such as:
173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsyncIt consists of the refresh rate in Hz, horizontal and vertical resolution, options for horizontal and vertical synchronisation. The program cvt(1) can provide suitable modeline string.
**transform=**normal
The transformation applied to screen output (string). The transform key can be one of the following 8 strings:
normal Normal output.
90 90 degrees clockwise.
180 Upside down.
270 90 degrees counter clockwise.
flipped Horizontally flipped
flipped-90 Flipped and 90 degrees clockwise
flipped-180 Flipped upside down
flipped-270 Flipped and 90 degrees counter clockwise**scale=**factor
The scaling multiplier applied to the entire output, in support of high resolution (“HiDPI” or “retina”) displays, that roughly corresponds to the pixel ratio of the display’s physical resolution to the logical resolution. Applications that do not support high resolution displays typically appear tiny and unreadable. Weston will scale the output of such applications by this multiplier, to make them readable. Applications that do support their own output scaling can draw their content in high resolution, in which case they avoid compositor scaling. Weston will not scale the output of such applications, and they are not affected by this multiplier.An integer, 1 by default, typically configured as 2 or higher when needed, denoting the scaling multiplier for the output.
**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.

path=/usr/libexec/weston-keyboard
sets the path of the on screen keyboard input method (string).
KEYBOARD SECTION
**keymap_rules=**evdev
sets the keymap rules file (string). Used to map layout and model to input device.
**keymap_model=**pc105
sets the keymap model (string). See the Models section in xkeyboard-config(7).
**keymap_layout=**us,de,gb
sets the comma separated list of keyboard layout codes (string). See the Layouts section in**xkeyboard-config(7).**
**keymap_variant=**euro,,intl
sets the comma separated list of keyboard layout variants (string). The number of variants must be the same as the number of layouts above. See the Layouts section in xkeyboard-config(7).
**keymap_options=**grp:alt_shift_toggle,grp_led:scroll
sets the keymap options (string). See the Options section in xkeyboard-config(7).

**font-size=**14
sets the size of the terminal font (unsigned integer).
**term=**xterm-256color
The terminal shell (string). Sets the $TERM variable.
