Same problem here after upgrading three days ago from Ubuntu 14.04.4 (that worked) to 16.04.1 (that's broken as explained below).
Desktop Environment: GNOME-Flashback:Unity (gnome-flashback-metacity) Dual screen, notebook + external VGA monitor. NVidia Quadro FX 770M, 3.3.0 NVIDIA 340.96 I set the primary monitor to the notebook screen using nvidia-settings, and the setting stuck across logout: I see the gnome panel properly moving to the notebook screen when the Gnome GUI comes up after logout and reboot. OTOH, my notebook is positioned to the right of my VGA monitor, and that's where the problem starts. The system insists on placing the notebook built-in screen to the left of the monitor. If I set the primary monitor (notebook built-in screen) to the right of the VGA screen using nvidia-settings, I get what I want for the current session. But this setting is lost after the next session logout (or reboot for that matter). If alternately, I set the primary monitor (notebook built-in screen) to the right of the VGA screen using "System Settings / Displays", I get what I want for the session, but this setting is also lost after the next logout (reboot). The trick suggesting at #39 doesn't work for me (to start with, I have no etc/gnome-setting-daemon/xrandr on my system) To add insult to injury, the upgrade also brought me a similar problem with the alsamixer settings: They are set to some default muted values that makes the machine totally silent at each session start, and whatever way I set them, they are reset to the same muted default values upon the next logout / login. Not sure whether I also owe this to gnome-shell, but that's what I suspect. I use "sudo alsactl" to manually handle the problem and reload the proper alsamixer value, but I hate it. I have so far not found any simple, reliable fix or workaround for either problem. <sigh> -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1292398 Title: Second screen position isn't saved from one session to another Status in elementary OS: Fix Released Status in gnome-settings-daemon: Unknown Status in gnome-shell: Confirmed Status in Ubuntu GNOME: Confirmed Status in Ubuntu GNOME trusty series: Confirmed Status in Ubuntu GNOME xenial series: Confirmed Status in Ubuntu GNOME Flashback: Confirmed Status in Unity: New Status in gnome-settings-daemon package in Ubuntu: Triaged Status in gnome-shell package in Ubuntu: Triaged Bug description: (Noticed on Ubuntu 14.04 beta 1 GNOME) At work I have a second screen, which I prefer to virtually put on the left side of my laptop screen. Using gnome-control-center I can change the position of the second without problem. But when I disconnect the second screen (to work on another place) and then connect it again OR if I just power off the laptop and turn it on again, the second screen position is set back to the default right position.
