[SOLVED] TTY switching not available after starting SDDM

When inside an SDDM session or then logging in into KDE (x11 or Wayland) seems to disable TTY switching. Either C-M-Fn or sudo chvt n do not work. The latter doesn't have any output and returns exit code 0. Side note: I use SDDM on vt1 (this seems to be the default, and I haven't changed the configuration file), agetty on vt2 and kmscon on VT's 3 through 6, so at least vt2 should work, right?

I am using nvidia-dkms 535.54.03 for my graphics driver, kernel 6.4.3 (with tkg patches, but I don't think that matters for this issue) and plymouth on the bgrt theme, with the drop-in snippet from the wiki to allow a "smooth transition" between it and sddm. I have early KMS setup, so that should be in order.

Smells somewhat like https://bbs.archlinux.org/viewtopic.php?id=287092
Does SDDM matter or will any display server ("startx") do?

Re: [SOLVED] TTY switching not available after starting SDDM

I'm sorry, since I couldn't directly open a tty from startup, I couldn't verify if agetty was actually correctly running, but I incorrectly recalled it doing so.

Here's what I did:
1. mask display-manager.service on startup
2. actually enable agetty on all tty's
3. disable kmscon

kmscon doesn't seem to work when early KMS isn't setup correctly, which it wasn't. Alright, marking as solved.
