Yoga 2 Pro gnome-settings-daemon stops working after a while

[vladimiroltean]

Hi, I didn't know of a better place to post this. I am using Arch Linux with GNOME 3.18, and this proxy to provide screen auto rotation. After a while however (can't pinpoint what's causing it), auto rotation stops working. I have checked the output of monitor-sensor and it is still running, giving messages such as:

\ Message: Accelerometer orientation changed: left-up

Either reloading GNOME shell (Alt-F2 + r) or running "killall gnome-settings-daemon" help (temporarily) solve the issue, but I'd much rather prefer it not happening. The output of "G_MESSAGES_DEBUG=all /usr/sbin/iio-sensor-proxy" is:

This is a problem. Is the kernel producing warnings? As which user are you running this helper?

[vladimiroltean]

Directly as a login user.

[hadess]

That won't work, the iio-sensor-proxy needs to run as root.

[vladimiroltean]

Yes, sorry for the false alarm, running as root produces apparently correct results in the log:

However, gnome-shell still does not rotate the screen, although it does seem to pick up events from iio-sensor-proxy. Running "/usr/lib/gnome-settings/daemon/gsd-test-orientation" tells me it's picking up orientation info, and at least it's trying to rotate the screen.

The bug seems to be related to the Intel i915 graphics kernel module, because each time I run "xrandr -o left", I get this message in the kernel log:

As can be seen, I am running the latest stable kernel, 4.2.3. I will also try the mainline version.

/usr/lib/gnome-settings/daemon/gsd-test-orientation will only run if you disabled the orientation plugin. Re-enable it and it should pick up the changes. Make sure to use GNOME 3.18, it won't work with older versions.

After more investigation, it seems that this piece of software works correctly, with all debug messages showing what they should. However, auto rotation in GNOME doesn't properly work at startup (after 5-6 successful rotations it stops), until I restart the shell (Alt-F2 + r). It works completely fine after that (including after waking up from sleep). I am trying to run the following immediately after reboot:

gsettings set org.gnome.settings-daemon.plugins.orientation active false /usr/lib/gnome-settings/daemon/gsd-test-orientation

It shows the following sample output:

(gsd-test-orientation:29957): orientation-plugin-DEBUG: Found orientation 'normal' for accelerometer (gsd-test-orientation:29957): orientation-plugin-DEBUG: Orientation changed to 'normal', switching screen rotation (gsd-test-orientation:29957): orientation-plugin-DEBUG: Found orientation 'left-up' for accelerometer (gsd-test-orientation:29957): orientation-plugin-DEBUG: Orientation changed to 'left-up', switching screen rotation (gsd-test-orientation:29957): orientation-plugin-DEBUG: Found orientation 'normal' for accelerometer (gsd-test-orientation:29957): orientation-plugin-DEBUG: Orientation changed to 'normal', switching screen rotation

Unfortunately, after running "gsettings set org.gnome.settings-daemon.plugins.orientation active true" again, the effective screen rotation does not happen. I am moving to the gnome-settings-daemon issues page, since I believe the bug to be there.

As iio-sensor-proxy is reading the sensor correctly, reporting it to the desktop to use, and that gsd-test-orientation can read the data, it looks like a GNOME bug, not one in iio-sensor-proxy. Please file a bug against gnome-settings-daemon at https://bugzilla.gnome.org referencing this bug, and make sure that you're using the newest stable version of gnome-settings-daemon as well.
