weston.ini(5)
NAME
weston.ini - configuration file for Weston - the reference Wayland compositor
INTRODUCTION
Weston obtains configuration from its command line parameters and the configuration file described here.
DESCRIPTION
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'.
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
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.
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).
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-location=top
sets the location of the panel (string). Can be top, 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)
LAUNCHER SECTION
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
OUTPUT SECTION
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, an 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.
INPUT-METHOD SECTION
path=/usr/libexec/weston-keyboard
sets the path of the on screen keyboard input method (string).
KEYBOARD SECTION
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.
TERMINAL SECTION
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.
XWAYLAND SECTION
path=/usr/bin/Xwayland
sets the path to the xserver to run (string).
