I booted Official OpenWrt 21.02.0(Sep 2 2021) from USB on Miix510 12IKB and left it alone for about 7 hours. When I came back to it, its screen was still on. It seemed that the screen is always on.
Are there methods of making the screen turned off
- by default
- after a certain time without keyboard input such as 3 minutes
- via the console
