Hi,
Thus far our assumption always was that the acpi backlight works better than the intel native backlight. So everything only uses the intel backlight if there's no other backlight driver by default. So if I should merge this as a general solution for Windows 8 machines not working properly, we first need to figure out what windows does on these machines and either disable the acpi backlight or adapt it.
I fully agree to that. Making acpi_video control usable is preferable over using intel_backlight. As I lack the detail knowledge about the ACPI video stuff, I'd be great of one (or some) of you guys could look at the mentioned bug report ([1]) and comment on what the problem might be. I have added the basic needed information already and would be happy to provide any needed debugging info.
Adding more kernel options is not a viable solution for the backlight mess imo.
Actually I'm fine with hardcoding the percentage as well ;) I just figured it might make sense to make it controllable for special-case uses, while still making intel_backlight usable for the 'normal' use case.
