Configure X11 Touchscreen Gestures
NOTE: The techniques and methods described below do not work in Wayland.
Installing the evdev Dependency
The following configurations require the evdev. If it is not already installed, install it with sudo apt install xserver-xorg-input-evdev. For more information about the evdev options and their syntax please see the evdev manpage and the InputClass configuration options.
Add a long-touch right-click gesture
The following procedure will configure X Windows so a long-touch (touch and hold) will simulate a right-click and display a context menu.
- Create the file /etc/X11/xorg.conf.d/90-touch-gestures.conf with the following contents:
Section "InputClass" Identifier "touch gestures" Driver "evdev" MatchProduct "Microchip Technology Inc. AR1100 HID-MOUSE" Option "EmulateThirdButton" "1" Option "EmulateThirdButtonTimeout" "750" Option "EmulateThirdButtonMoveThreshold" "50" EndSection - Reboot
In Mono applications, this feature can cause the MouseDown event to delay. If your application depends on an immediate MouseDown event, please delete the file /etc/X11/xorg.conf.d/90-right-click.conf.
Add a touch-and-drag scroll gesture
The following procedure will configure X Windows so when you touch and drag your finger up and down the touchscreen it will scroll.
- Create the file /etc/X11/xorg.conf.d/90-touch-gestures.conf with the following contents:
Section "InputClass" Identifier "touch gestures" Driver "evdev" MatchProduct "Microchip Technology Inc. AR1100 HID-MOUSE" Option "EmulateWheel" "1" Option "EmulateWheelButton" "1" Option "EmulateWheelInertia" "10" Option "EmulateWheelTimeout" "200" Option "YAxisMapping" "4 5" EndSection - Reboot
