SUMMARY

KDE Neon unstable, when booting, only one screen is available even though the configure display setting device shows two, but not side by side, only in the device dropdown (it shows "built in and Lenovo external). Only one screen works, the other says that it has no signal or when on the laptop it's just black.  Scaling is 100 on both settings. This is with both direct plug into the laptops hdmi port or using a dock. Unplugging and lugging it back does nothing. I dual boot with Zorin and with wayland/gnome it works as it should. To make Neon work with dual screens I have to revert back to x11 at login.

With or without Nvidia Driver.

Not sure if it's a part of the issue, but, on boot or logout, SDDM has a messed up screen too.
