Update gaze10/11 for backlight control on kernel 6.2+ #272

Add new system76-driver option to switch to "native" backlight control Update gaze10/11 to use new option

thomas-zimmerman commented 1 year ago

Manual changes of the acpi_backlight=native known to work on gaze10. Testing on customer system where this was noticed (ZD:121274)

I wonder if this is something we could fix in the kernel so a boot parameter isn't necessary?

I think the 6.1 refactor for backlight control might have been when this broke: https://hansdegoede.livejournal.com/26427.html

Customer on gaze11 verifies that switching to native backlight control returns backlight control to a working state.

@jacobgkau : I suspect that you are correct but I did not have a easy way to boot 6.1 kernels to test.
