Automatic brightness control is flickering in Gnome, so I checked sensor wi= th monitor-sensor command (iio-sensor-proxy). it shows following behavior: monitor-sensor --light Waiting for iio-sensor-proxy to appear +++ iio-sensor-proxy appeared =3D=3D=3D Has ambient light sensor (value: 316,000000, unit: lux) Light changed: 299,000000 (lux) Light changed: 0,030000 (lux) Light changed: 299,000000 (lux) Light changed: 0,030000 (lux) Light changed: 299,000000 (lux) Light changed: 0,030000 (lux) Light changed: 305,000000 (lux) the 0.03 is unexpected has it has never been that dark. it seems it's not a iio-sensor-proxy bug as I can see similar behavior by checking directly content of here : /sys/bus/iio/devices/iio:device0/in_illuminance_raw I checked the behavior on windows to make sure it's not an hardware failure from my sensor. While I cannot have direct access to raw sensor data on windows, the automa= tic brightness is perfectly smooth: no flickering of any kind. I didn't found sensor name: =E2=9D=AF cat /sys/bus/iio/devices/iio:device0/name als But if there is other place I could look, let me know. --=20 You may reply to this email to add a comment.
