Automatic screen brightness in Ubuntu Unity with Xenial? #79

Closed FMuro closed 8 years ago

FMuro commented 8 years ago

First of all, I'd like to thank you for your work. I've installed iio-sensor-proxy in Xenial on a macbook pro 8,2 and the light sensors are detected, I've check this with monitor-sensor. However, the screen brightness or keyboard backlight don't change. I think that Unity in Xenial is mostly Gnome 3.18, so I was expecting this to work. Is there anything I could do to fix this? BTW, it worked in Fedora 23 on the same computed, which I've been using for a while, but have abandoned because it consumes a lot of memory for no apparent reason.

GNOME 3.18 should be new enough, please gather debug output as per README.md

That's most likely incorrect.

Thanks for your answer, hadess! Here you are:

* (process:3185): DEBUG: Found IIO poll light at /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:1a/ACPI0008:00/iio:device0 * (process:3185): DEBUG: Found device /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:1a/ACPI0008:00/iio:device0 of type ambient light sensor at IIO Polling Light sensor

BTW, the Fedora thing may well be that I don't remember, but it might also be due to other things, such as the fact that I used the Radeon card with it, instead of the integrated intel card.

is that it? Can you run "monitor-sensor" in a separate window/shell as well?

FMuro commented 8 years ago

I'm afraid I run the debugging command in a constant light intensity. Now, I've approached a lantern to the light sensor so that you can see the variation. I've uploaded two screenshots. One the is the usual output of monitor-sensor with iio-sensor-proxy running. The other one is the result of your debugging instructions. I hope this is what you meant.

I am in the same boat (on a Samsung ATIV 700T, Ubuntu 16.04, Unity 7.4.0)

iio-sensor-proxy and the device are reporting brightness changes correctly. From the screenshots, I see you're not using GNOME either. You'd need to ask Ubuntu/Canonical why there's no integration or why that integration doesn't work, because they don't use gnome-settings-daemon.
