Indeed we had this airplane mode discussion two weeks ago: Why don't we?


To completely silence the radio:

  1. !/bin/bash

rmmod usb8xxx mv /lib/firmaware/usb8883.bin /lib/firmaware/usb8883.bin.quiet

It will survive reboots.


To bring it back:

  1. !/bin/bash

mv /lib/firmaware/usb8883.bin.quiet /lib/firmaware/usb8883.bin rmmod usb8xxx; sleep1; modprobe usb8xxx

No reboot necessary.


Backlight

The backlight levels can be modified by writing to /sys/class/backlight/dcon-bl/brightness. The backlight seems to have 15 levels of color-mode brightness (1-15) and one level indicating black and white mode (0).

Here're examples of how to modify the backlight levels from the Terminal:

           sudo bash -c "echo 0 > /sys/class/backlight/dcon-bl/brightness"
           sudo bash -c "echo 15 > /sys/class/backlight/dcon-bl/brightness"
