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.

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—>The Wayland Protocol :: Fedora Docs

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.
