NetBSD thinkpad 10.0_RC2 NetBSD 10.0_RC2 (GENERIC) #0: Mon Jan 1 14:04:52 UTC 2024 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
On this Lenovo Thinkpad T450 laptop, the brightness keys don't work correctly. The "increase screen brightness" key does not work at all, and the "decrease screen brightness" key always sets the screen brightness to the minimum or a near-minimum value.
The screen brightness is correctly adjusted by the command
sysctl -w hw.acpi.acpiout0.brightness=N
where N is anywhere from 0 to 100, however a subsequent
sysctl hw.acpi.acpiout0.brightness
command to read the value back always reports a value of 100. When N is 0, the display is not turned off, but I do not know whether this is the expected behavior. It would be nice if setting the brightness to zero turned off the backlight.
The screen brightness keys on the keyboard similarly do not affect the value of the brightness reported by sysctl.
Additionally, the screen brightness is reset to 100% whenever I plug in or remove the AC power cord. I am not sure whether this is a bug, but I would like to disable that behavior either way.
Below is a copy of the _BCM, _BCL and _BQC methods from the output of acpidump -dt. I found two instances of each, so I am including them both. Below that is a copy of the output of dmesg.

>How-To-Repeat:
Press the "increase screen brightness" key and watch the screen brightness not change. Run sysctl hw.acpi.acpiout0.brightness and see that it reports a value of 100, even if the screen brightness is not physically at 100%.
Press the "decrease screen brightness" key and watch the screen brightness change to the minimum or a near-minimum value. Run sysctl hw.acpi.acpiout0.brightness to see that it reports a value of 100 even though the screen is not physically at 100%. Note that subsequently pressing the "increase screen brightness" key has no effect.
Run sysctl -w hw.acpi.acpiout0.brightness=N where N is any value from 0 to 100 and see that the screen brightness physically changes to the requested value, as intended, except that a value of N of 0 does not turn off the backlight. Run sysctl hw.acpi.acpiout0.brightness and observe that the reported value is 100, regardless of the physical screen brightness.
Unplug the AC power cord and watch the physical screen brightness change to 100%.
Plug in the AC power cord and watch the physical screen brightness change to 100%.
