Some Lenovo laptops have keyboard backlights, and they can be turned on using
Fn + Space . There are three states: off, normal and bright.
When I start Ubuntu, these laptops always default back to a burning sun screen brightness and the keyboard lights off.
I want a medium brightness and keyboard lights on by default, because I usually use this laptop in dark environments.
The backlight is easy. Internet is filled with information about this.
echo 10 > /sys/class/backlight/acpi_video0/brightness
TURN-ON THE UNKNOWN SOURCESTo do this, go to Android Menu Settings Security, and tap on Unknown Sources and turn it on. Change showbox default player. This is an important step.
But how do I turn on the keyboard backlights with a command?I've been looking here but it seems to do nothing:
/sys/class/leds/tpacpi::thinklight

I tried
for i in {1.32}; do xset led $i; done but nothing changes. Perhaps the keyboard backlight for Lenovo laptops has a proprietary driver and can only be controlled through tpacpi ?

for i in $(find /sys/devices/platform/thinkpad_acpi/leds/ | grep /brightness); do echo 255 > $i; done of no avail.

My T450s would not re-enable keyboard backlight upon resume with kernels older then 4.6. FWIW, with 4.6 now, keyboard backlight is set to the brightness it had before suspend.
