further update - prior to 17.10, my logon routine was to boot up my laptop with the screen open, then as soonn as my 2 monitors picked up the screen image during the boot up process, I closed my laptop screen fully shut, and completed the rest of the boot up process, including entering my logon password on the montiors, with the left one showing as my default primary monitor. This worked every time.
Since 17.10 this big 1726538 has occurred. I discovered today though that if I keep my laptop screen fully open throughout the boot up and logon process and type my logon password into the logon prompt on th laptop screen, then let the boot up process run fully, with the laptop screen open, when the boot up process ends the monitors are correct with the primary default monitor on the left and bug 1726538 does not occur. I close my laptop screen fully then and all is well. No issues. However if I close my laptop screen part way through the boot up process, before it is fully finished, the bug reappears and my montiors are switched round again. For me this is a decent work around fix, although I'm not sure it's working as designed so probably still valid to keep this bug open and investigate some more. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1726538 Title: Dual monitor configuration not saved across logout / login Status in gnome-shell package in Ubuntu: Confirmed Bug description: System76 Galaga UltraPro laptop. Two monitors, one plugged into the DisplayPort and one plugged into HDMI. I use the Displays settings page to tell the system which monitor is on the right and which is on the left, and tell it to make the left monitor the primary one. All is well. Then I log out and log back in. Now the two monitors are reversed -- i.e., it thinks that the monitor on the right is on the left and vice versa -- and the right monitor (which, remember, it thinks is on the left) is the primary one. In short, it forgets the configuration I told it to use immediately before logging out.
