About the LCD screen brightness. At lest the 7 inch touch one I have.

Went to try and test dimming it but so I went to this web site. Went to the folder /sys/class/backlight and did a git clone https://github.com/linusg/rpi-backlight.git because that folder is not there. But it says Permission denied and I log in as root. I guess it’s not a real root or I just don’t know why.

I was going to take the SD card out and mount it in another Ubuntu. But it’s to hard I would have to open up this hole case to get the SD card out.

If could do the dimming on the command line there are other web sites that say how to install a light sensor.

Tested tying it another way but it don’t work ether.

root@bed-max2play:~# pip install rpi_backlight
