Newer kernel command

[ThoreauHenry]

I just wanted to post a command for newer 5.x kernels with security features that disallow this program to function.

This is primarily for Dell's with no BIOS option to code the timeout. It will be active at OS boot.

The command below is for keyboard led timeouts.

cat /sys/class/leds/dell::kbd_backlight/stop_timeout

sudo echo 12h > /sys/class/leds/dell::kbd_backlight/stop_timeout

Place whatever time period you wish into the echo, and it will hold across reboots.

Take care.
