--- Comment #27 from Michael Franzl <michaelfra...@gmx.at> 2009-12-07 15:58:57 --- (In reply to comment #25) > I forgot to document the light sens thing in > Documentation/ABI/testing/sysfs-platform-asus-laptop :/ > You can use ls_switch and ls_level to control the light sensor under > /sys/devices/platform/asus-laptop/ Ah, THAT worked! What did we apparently find out? When CONFIG_ASUS_LAPTOP is NOT compiled in the kernel, the light sensor is switched OFF by default. The sleepstates mem and disk somehow switch the ambient light sensor ON. And then it cannot be switched off again. When CONFIG_ASUS_LAPTOP IS compiled in the kernel, the light sensor is switched ON by default, which leads to screen brightness controlled by PWM (pulse width modulation). But now we know how to switch off this annoying PWM, which caused me headaches when looking at it the whole day! Thank you both for your assistance! -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
