You could try the following suggestions from Karl:

Steps for this would be something like:

  1. Install 'gtk3-demo' program. On Debian, it's found in the
     'gtk-3-examples' package.
  2. Run gtk3-demo
  3. Switch to the "Gestures" page
  4. Click "Run"
  5. In the window that opens up, perform some touch gestures,
     and see if the window reacts to it in any way. For me,
     a one-finger drag results in a line being drawn, and a
     two-finger gesture results in a square being shown.

Steps for this:

  1. Install the 'xinput' program. On Debian, it's found in the
     'xinput' package.
  2. Run 'xinput --list' to see a list of your devices, and note
     the device ID for your touch device.
  3. Run 'xinput --test-xi2 <id>', where <id> is the id from the
     previous step.
  4. Perform some touch gestures, and paste the output of the
     command.
