Can SDDM startup a bare Xorg server alongside a wayland session?

So I'm intersted in a setup where I use wayland for my daily driving, but I have a bare x server in another VT that I can launch applications in (I'm aware of xwayland, this is actually so I can allow a couple applications to get past a few wayland/nvidia driver limitations).

So I'd like to know if SDDM is capable of doing this. I *could* start the X server on my own but i'd rather it be automated with SDDM when I login and so SDDM does the job of killing it when I log out.

I don't think SDDM can facilitate two sessions concurrently. I'm open to being corrected about that. However, as a test, I started a Plasma X11 session (via SDDM) then opened a new VT, logged in as a user and started a Plasma Wayland session with

Code:

dbus-run-session startplasma-wayland

I did this on a single screen laptop, where switching between the two graphical VT sessions allowed me access either session as desired. I know it is not automated or managed via a display manager as you requested, but it does work.

Thats good to know that it'll work even if I have to do it manually though.

I wonder if theres a way to at least hack it into a startup and logout script, I don't think my user would have the permissions to start a xorg server on another VT though.
