I’m running EndeavourOS with Sway. It boots up and goes all the way to the login screen. However, after I login, the screen goes completely black. When I try Super+Shift+E to exit Sway, nothing happens. Any ideas on how I could fix this?

Some more information?
NVIDA Graphics?
Perhaps try switching to another tty CTRL+ALT+F1/F3 etc then launch sway by using the command “sway”

and… currently, lightdm is causing an issue on sway… so try switching it to something other can help 
Sweet, that worked!
Here’s the output of the two commands:
inxi -Fxxc0z --no-host | eos-sendlog
journalctl -b -0 | eos-sendlog

Okay! How do I switch from lightdm to something else?

According to the Arch wiki, GDM or SDDM would do. I already have SDDM (because I have KDE Plasma). I’ve added Sway just now and, on logging in, the Sway session is available & functional.
To activate SDDM after installing it, see dalto’s advice here.
sudo systemctl enable sddm -f
GDM ,sddm ok might think light option

What I did was disable lightdm via systemctl and start sway from tty just typing “sway” at command prompt.

I’ve gone DM-free as well. This post suggests that getting a black screen maybe due to a “timing related thing” (race condition?) and that older (spinning drives) maybe less affected.

Awesome, that worked, thanks so much!
Switching to another TTY, i.e. Ctrl + Alt + F2, and manually launching Sway via sway --unsupported-gpu works for me. I then log-out, I go back to Ctrl + Alt + F1, and I am landed in SDDM’s login screen, I type my password and Sway launches then.
How do we render all this unnecessary?
