For anyone who is curious with the Linux problem on Lenovo Legion 7, here are the list:
- Display brightness cannot be changed by the Fn key, it’s fixed at max brightness. You can change the brightness by the xrandr command, but seriously …
- Cannot go to the sleep state properly: when the system wakes up and the screen is black and you must force shutdown the system.
- **Ridiculous **power consumption: it takes 2 hours to drain the battery from 100% to 9% just doing GIMP while playing youtube videos, with 165-Hz refresh rate and max brightness display.
- Audio speaker does not work, but earphones works fine.
So for Linux, beware that anyone should stay away from the Legion 7 model.
