How can I choose between an X and Wayland session before login?

I remember at one point, maybe in Fedora 27, I was able to pick from a dropdown menu whether to login with an X session or a Wayland session. As mentioned in my related post, Wayland isn’t handling rotating a screen very well right now, so I’d like to use X temporarily. I can do this with a config file placed in /etc/X11/xorg.conf.d, but since deleting or moving a configuration file every time I want to switch is inefficient, I’d prefer to use the dropdown menu on login.

Is there still a way to enable this menu?

Maybe is a silly answer but Did you click on the cogwheel when you select a user? and type your password…

Click there and you can see:

  • Gnome Wayland
  • Gnome Xorg
  • Gnome Clasic

once selected it is selected unless you change it…

That is what you’re asking?

you can also do it automatic:

Edit /etc/gdm/custom.conf and uncomment this line:

[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false

This is on the KDE spin, so there’s no cogwheel. I’ll see if I can tag the original question to be more specific.

To answer your question, yes, I’m looking for an equivalent to that menu in KDE.

on sddm you must use this menu :

That menu doesn’t show up for me:

choose user you want to login with. and then that menu will be appear.

The menu doesn’t appear even when I have my user account selected. It doesn’t appear on a cold boot, it doesn’t appear if I reboot, and it doesn’t appear if I log out.

If you use KDE you should read it first—>https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/Wayland/

You should need install the plasma-wayland session to see this option in the menu but i dont know how stable it is in KDE… Sure you can find a bit more of info about it in google.
