The login screen issue is bug 1760849. The login screen runs as a different user (gdm) so it has its own monitor configuration. You can overwrite that as root by copying ~/.config/monitors.xml to ~gdm/.config/monitors.xml
It's important each bug only describes one issue, so this can be about the problem after login. I think the dock is the most important factor here and it sounds like bug 2109692. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2110949 Title: Loss of monitor config upon reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2110949/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
