Information How to change screen brightness on Panasonic Toughpads

To change the screen brightness on a MetalMapperII Panasonic Toughpad:

1) If you want to type easily, plug a keyboard into the USB socket in the side of the toughpad.  Otherwise, use the screen keypad.

2) Open a terminal window (using the Applications menu).

3) Type the following command:

sudo bash -c "echo 892 > /sys/class/backlight/intel_backlight/brightness"

You will need to enter a password, which is the default password for the standard user. To set different levels, replace the number 892 with other numbers.  892 is the maximum number allowed; lower numbers will result in a dimmer screen.

The change should take place immediately.

Then close the terminal window and return to normal use.
