(Get the code!)
Still present in 19.04, although as a workaround, the nvidia drivers have reverted to installing without modeset=1, so external monitors work, and Optimus users get dreadful tearing on their laptop's internal screen.
With modeset=1 (which in my case was a setting preserved during the update to 19.04):
At the login prompt (using gdm3) external monitors are powered on and display a background graphic.
During session start, they are lost.
External monitors work with lightdm or sddm3, both supported display managers in Ubuntu, so this remains the workaround.
So odd that Fedora doesn't care about this. It's a dreadful welcome to Linux moment. Using gdm3 as the default display manager seems insane given this bug.
