Keyboard backlight not turning on, can't find kdb_backlight [SOLVED]

As I stated above, The backlight on my keyboard won't turn on. The system went to sleep once, froze when I woke it up, had to be shutdown, and the backlight has been off since.

I'm not even sure where to start investigating this one, but my laptop is a Razer Blade 15 (2019) Mercury, and I have a ticket open with openrazer for not being able to start polychromatic. I'm trying to configure the keyboard from the command line for right now.

This fixed it.

Razer doesn't have the kbd_backight layout other keyboards have. This should probably be noted in the wiki

ls /sys/bus/hid/drivers/razerkbd/<version containing device_type, matrix files, etc>
echo -n "2" > matrix-effect-spectrum
cat matrix_brightness
0 # verifies led is turned off
echo -n "255" > matrix_brightness
