NAME

lisgd - libinput synthetic gesture daemon

SYNOPSIS

lisgd [-d devicepath] [-g gesturespec]... [-t threshold] [-m timeoutms] [-o orientation] [-w width] [-h height] [-r degreesofleniency] [-v]

DESCRIPTION

lisgd (or libinput synthetic gesture daemon) lets you bind gestures based on libinput touch events to run specific commands to execute. For example, dragging left to right with one finger could execute a particular command like launching a terminal. Directional L-R, R-L, U-D, and D-U gestures and diagnol LD-RU, RD-LU, UR-DL, UL-DR gestures are supported with 1 through n fingers and can be bound to the screen's edges and/or made sensitive to the distance of the gesture.

Unlike other libinput gesture daemons, lisgd uses touch events to recognize synthetic swipe gestures rather than using the libinput's gesture events. The advantage of this is that the synthetic gestures you define via lisgd can be used on touchscreens, which normal libinput gestures don't support.

This program was built for use on the Pinephone however it could be used in general for any device that supports touch events, like laptop touchscreens or similar. You may want to adjust the threshold depending on the device you're using.

OPTIONS

Path of the dev filesystem device to monitor (like /dev/input/event1).

Allows you to bind a gesture wherein nfingers is an integer, gesture is one of {LR,RL,DU,UD,DLUR,DRUL,URDL,ULDR}, edge is one of * (any), N (none), L (left), R (right), T (top), B (bottom), TL (top left), TR (top right), BL (bottom left), BR (bottom right) and distance is one of * (any), S (short), M (medium), L (large), actmode is R (release) for normal mode and P (pressed) for pressed mode (but this field may be omitted entirely for backward compatibility), command is the shell command to be executed.

The -g option can be used multiple times to bind multiple gestures.

Number of milliseconds gestures must be performed within to be registered. After the timeoutms value; the gesture won't be registered.

Number of 90-degree rotations to translate gestures by. Can be set to 0-3. For example using 1; a L-R gesture would become a U-D gesture. Meant to be used for screen-rotation.

Number of degrees offset each 45-degree interval may still be recognized within. Maximum value is 45. Default value is 15. E.g. U-D is a 180 degree gesture but with 15 degrees of leniency will be recognized between 165-195 degrees.

Threshold in libinput units (pixels) after which a gesture registers. Defaults to 125.

Threshold in libinput units (pixels) after which a gesture registers when fingers are not lifted. Defaults to 60.

Allows you to specify the width of the screen area to be used for edge-based gestures. Should be used in conjunction with -h. If unset, and either the DISPLAY or WAYLAND_DISPLAY env var is set, X/Wayland dynamic screen geometry detection will be used instead.

Allows you to specify the height of the screen area to be used for edge-based gestures. Should be used in conjunction with -w. If unset, and either the DISPLAY or WAYLAND_DISPLAY env var is set, X/Wayland dynamic screen geometry detection will be used instead.

Enables verbose mode which prints debugging messages.
