Does anyone have a verified method of controlling the brightness level of the 7" touchscreen? I did find a method to turn the entire display on and off: #!/bin/bash onOrOff=$1 if [ -z $DISPLAY ]; then export DISPLAY=":0" # echo "Created the DISPLAY env variable" fi if [ $onOrOff == 0 ]; then xset c b s off xset -dpms xset s noblank echo "touchscreen blanking turned OFF." else xset c b s on xset dpms 3600 3600 3600 xset s blank echo "touchscreen blanking turned ON." fi Which I turned into the above-listed shell script.

Controlling touchscreen brightness

Does anyone have a verified method of controlling the brightness level of the 7" touchscreen?

I did find a method to turn the entire display on and off:

#!/bin/bash

onOrOff=$1

if [ -z $DISPLAY ]; then

export DISPLAY=":0"

# echo "Created the DISPLAY env variable"

if [ $onOrOff == 0 ]; then

xset c b s off

xset -dpms

xset s noblank

echo "touchscreen blanking turned OFF."

else

xset c b s on

xset dpms 3600 3600 3600

xset s blank

echo "touchscreen blanking turned ON."

Which I turned into the above-listed shell script.
