Suspend
Two methods... you have to adjust the brightness afterwards
- Press
Fn-Esc - Type
$ systemctl suspend
Adjusting brightness
stack overflow says any value 0 to 20 works, but it was at 255 after suspend
sudo su -c 'echo 255 > /sys/class/backlight/lcd0/brightness'
sudo su -c 'echo 0 > /sys/class/backlight/lcd0/brightness'
