Issue

You are using a touchpad instead of a mouse and you want to reverse the scrolling direction to have natural scrolling – with the screen content moving synchronously to the fingers' movement on the touchpad.

Problem

There is no "reverse scrolling" parameter in IGEL Setup.

Solution

  1. Open the device's configuration either locally or in the UMS.
  2. Go to System > Firmware Customization > Custom Commands > Desktop > Final desktop command.
  3. Enter the following command:
    echo "pointer = 1 2 3 5 4 6 7 8 9 10 11 12" > ~/.Xmodmap && xmodmap ~/.Xmodmap

  4. Save the settings and restart your device.

    This will reverse the scrolling direction of a mouse wheel as well. Swapping 4 and 5 will reverse vertical scrolling, swapping 6 and 7 will reverse horizontal scrolling as well (if supported).
