Calibration

The touch screen calibration wizard assumes all touch screens connected to the computer are of the same make and model.

Before starting the calibration procedure, all touch screens must be connected to the computer and powered on. If touch screens will not be used for all stations, make sure that a touch screen is connected to the first video head. The touch screen calibration tool will use the touch screen connected to the first video head as the basis for configuring all other touch screens connected to the computer.

Refer to the main Userful Multiplier readme to identify the location of the first video head on the computer.

On the first boot after installing Userful Multiplier, you will be prompted to press F1 on the first video head to start the calibration procedure. Only an "X" icon is displayed on the other heads.

When you are prompted to press F1, press the F1 key on your keyboard and touch the screen connected to the first head. This will link the keyboard and touch screen to the first video head.

Step 1 of 3: (Calibrate Screen Size)

In this step, touch the screen and drag your finger around the outermost edges of the screen.

Keep dragging your finger around the edges of the screen until the "Min" and "Max" value on the screen stop changing.

Step 2 of 3: (Align Touch Points)

This step fine-tunes the touch screen. Touch the red square as it appears in each of the 9 key points on the screen.

Step 3 of 3: (Verify Calibration)

This step verifies the current calibration. Touch the screen and drag your finger to confirm that the pointer follows your finger.

  • Press Y on your keyboard to accept current calibration, or
  • Press N if the cursor does not follow your finger.

Horizontal (X-axis) Test (Optional)

Drag your finger horizontally across the screen.

  • Press Y on your keyboard if the pointer follows your finger, or
  • Press N to flip the X-axis.

Vertical (Y-axis) Test (Optional)

Drag your finger vertically up and down the screen.

  • Press Y on your keyboard if the pointer follows your finger, or
  • Press N to flip the Y-axis.

This concludes the touch-screen calibration process. If you wish to recalibrate the touch screens at a later date, you may do so by deleting the /etc/X11/userful.Mxorg.conf file.
