I have installed other window managers (FVWM/xfce4/awesome) besides Gnome. After upgrading to Fedora 29 I can only start gnome but not the other window managers directly.
Behavior: I start the machine and gnome login screen pops up. Then i select a different window manager. I get logged in and only get a black screen. After a change to another TTY and back the window manager starts.
What kind of behavior I'm expecting: The other window managers start without changing the tty.
It seems to be working with a plain fedora 29. Do you have any idea why this error occurs for me?
