I have the same/similar issue with Ubuntu 15.10, Unity, NVidia GTX 970, NVidia-352 prop driver.
My main display (the left one) is 1920x1080 plugged in via HDMI, and my second monitor is 1280x1024 via DVI. I setup my big monitor to be the left one, and my smaller to be the right one via Unity display settings. On system boot, boot screen and information is only shown on my smaller right monitor, left monitor doesn't even get a signal. On login screen, login credentials are only shown on the smaller right screen, with an expanded wallpaper showing on the left. After login, the left monitor is set correctly to the left, but full screen applications like most of my games start on the smaller right monitor by default. I can fix this after every login via NVidia Xserver Settings app and marking my left monitor as primary, then every game starts correctly on my left monitor. I worked around this now with a startup script setting the primary monitor to the left one via xrandr command. Can't understand why this issue is still low, as it is a very annoying usability bug. Hope this get's fixed in 16.04 LTS! -- 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 Flashback: 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.
