Setting acpi.debug_level to maximum and going throu= gh the debug layers one by one, I was not able to produce any sort of response from them. I would really like to know what is going on here.=20 Curiously, uninstalling the Lenovo hotkey driver in Windows does not break = them there, so I guess they nonetheless must be using some kind of standardized method to communicate with the OS? --=20 You may reply to this email to add a comment.
