weston.ini - configuration file for Weston - the reference Wayland compositor
Weston obtains configuration from its command line parameters and the configuration file described here.
Weston uses a configuration file called weston.ini for its setup. The weston.ini configuration file is searched for in one of the following places when the server is started: $XDG_CONFIG_HOME/weston.ini (if $XDG_CONFIG_HOME is set) $HOME/.config/weston.ini (if $HOME is set) weston/weston.ini in each $XDG_CONFIG_DIR (if $XDG_CONFIG_DIRS is set) /etc/xdg/weston/weston.ini (if $XDG_CONFIG_DIRS is not set) <current dir>/weston.ini (if no variables were set) where environment variable $HOME is the user's home directory, and $XDG_CONFIG_HOME is the user specific configuration directory, and $XDG_CONFIG_DIRS is a colon ':' delimited listed of configuration base directories, such as /etc/xdg-foo:/etc/xdg. The 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: [SectionHeader] Key1=Value1 Key2=Value2 ... The spaces are significant. Comment lines are ignored: #comment The section headers are: core The core modules and options libinput Input device configuration shell Desktop customization launcher Add launcher to the panel output Output configuration input-method Onscreen keyboard input keyboard Keyboard layouts terminal Terminal application options xwayland XWayland options screen-share Screen sharing options 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'.
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 xwayland=true ask Weston to load the XWayland module (boolean). modules=cms-colord.so,screen-share.so specifies the modules to load (string). Available modules in the /usr/lib/x86_64-linux-gnu/weston directory are: 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 wayland-backend.so x11-backend.so 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. 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. require-input=true require an input device for launch pageflip-timeout=milliseconds sets Weston's pageflip timeout in milliseconds. This sets a timer to exit gracefully with a log message and an exit code of 1 in case the DRM driver is non- responsive. Setting it to 0 disables this feature. wait-for-debugger=true 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. Boolean, defaults to false. There is also a command line option to do the same.
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
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). 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. background-color=0xAARRGGBB sets the color of the background (unsigned integer). The hexadecimal digit pairs are in order alpha, red, green, and blue. clock-format=format sets the panel clock format (string). Can be none, minutes, seconds. By default, minutes format is used. panel-color=0xAARRGGBB sets the color of the panel (unsigned integer). The hexadecimal digit pairs are in order transparency, red, green, and blue. Examples: 0xffff0000 Red 0xff00ff00 Green 0xff0000ff Blue 0x00ffffff Fully transparent panel-position=top sets the position of the panel (string). Can be top, bottom, left, right, none. 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. close-animation=fade sets the effect used when closing windows (string). Can be fade, none. By default, the fade animation is used. 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)
There can be multiple launcher sections, one for each launcher. 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
There can be multiple output sections, each corresponding to one output. It is currently only recognized by the drm and x11 backends. 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, a user may specify a modeline, such as: 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync It 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).
This section contains the following keys: 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). repeat-rate=40 sets the rate of repeating keys in characters per second (unsigned integer) repeat-delay=400 sets the delay in milliseconds since key down until repeating starts (unsigned integer) numlock-on=false sets the default state of the numlock on weston startup for the backends which support it. vt-switching=true Whether to allow the use of Ctrl+Alt+Fn key combinations to switch away from the compositor's virtual console.
Contains settings for the weston terminal application (weston-terminal). It allows to customize the font and shell of the command line interface. font=DejaVu Sans Mono sets the font of the terminal (string). For a good experience it is recommended to use monospace fonts. In case the font is not found, the default one is used. font-size=14 sets the size of the terminal font (unsigned integer). term=xterm-256color The terminal shell (string). Sets the $TERM variable.
path=/usr/bin/Xwayland sets the path to the xserver to run (string).
