   Section "InputClass"
       Identifier "touch gestures"
       Driver "evdev"
       MatchProduct "Microchip Technology Inc. AR1100 HID-MOUSE"
       Option "EmulateThirdButton" "1"
       Option "EmulateThirdButtonTimeout" "750"
       Option "EmulateThirdButtonMoveThreshold" "50"
   EndSection

2. 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.

The following procedure will configure X Windows so when you touch and drag your finger up and down the touchscreen it will scroll.
