the main switch/case. So execution falls back to acpi backlight,
that for this laptop does not work at all (tried vendor, native,
video). Tested also nvidia-wmi-ec-backlight, the module does not
even get loaded. Only solution i found is this patchset.

Set pwmgen_bit_count to have proper brightness inc/dec steps
even when driver_pwm_freq_hz (optional) is zero.
cat /sys/class/backlight/nv_backlight/max_brightness
255
Can now tune properly backlight from 0 to 255.

Hi all,
i am testing current mainline (6.7.rc8), on
a lenovo legion, with AD107M (chipset 197000a1).
Looks like somewhere at driver probe, screen turns
black and stays forever. If any hint, welcome.
I can help debugging, rebuilding and testing in case.
Regards,
Angelo Dureghello
