(In reply to comment #8) > The notebook also has an ambient light sensor. I did not find a way to read > the > values. Any hints? Under windows this is used to auto-adjust the screen > brightness according to the ambient light. This is a hint. I have a HP laptop with ambient light sensor. And I can not change the backlight manually in Windows, unless I disable the ambient light sensor. So can you please disable it and try again? (BTW, there is a hotkey to enable/disable the ALS on my laptop) -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
