Screen configuration is not preserved when logging out and logging back in

[Jonathan Kamens]

I have two identical monitors, with the dock on the left-hand side of the left monitor and the stickiness of the middle edge between the two monitors disabled.

When I log out and immediately log back in, my monitor configuration changes and now both monitors are mirroring the same content. I have to hit Command-P to get them to switch back to the non-mirrored configuration they were displaying immediately before I logged out.

This happens consistently, every time I log out and log back in.

The monitor configuration should be preserved when I log out and log back in.

Thank you for your bug report. You wrote "When I log out and immediately log back in", does it mean it only happens when you log back directly? what if you wait 30 seconds? Could you add your ~/.cache/upstart/unity-settings-daemon.log and ~/.config/monitors.xml to the bug?

Same problem.

There is no unity-settings-daemon.log for some reason, there are just the compressed ones, so I've attached the .1.gz file.

I will attach monitors.xml in a moment.

Status changed to 'Confirmed' because the bug affects multiple users.

Just upgraded from 14.04 to 16.04.1 and found this (and the workaround) via googling.

I drop my laptop on a dock with two vertically oriented (rotated to portrait) monitors. This was working fine before, now it lights them up without the rotation. Rotating them manually via System Settings -> Displays, undocking and docking again reverts to the wrong (landscape) orientation.

The ~/.config/monitors.xml looks fine but seems to be ignored.
Reloading the settings with

  killall unity-settings-daemon

gives me the correct orientation, which is read from the monitor.xml (editing the file by hand and killing u-s-d accepts whatever changes I make), it just doesn't get triggered on docking changes.

That's the workaround for now: kill u-s-d every time I dock to the workplace.
It would be nice for patchlvl 1 LTS upgrades to not break such basic stuff.
