I have Kubuntu 19.10 installed and then I installed gnome through apt thus having sddm and gdm3, my problem is that on gdm3 on the login screen I can only select plasma or ubuntu but can't find Wayland options while when I enable sddm I can select plasma, plasma on Wayland, ubuntu, ubuntu on Wayland. I tried editing: /etc/gdm3/custom.conf by commenting out WaylandEnable=false
#WaylandEnable=false
and also tried setting it to true same behavior
WaylandEnable=true
I have an iGPU and a dedicated Nvidia GPU running with the proprietary driver, selecting intel or nvidia through prime-select doesn't change anything and the Wayland sessions on both plasma and ubuntu work as expected through sddm
Edit: this question No option to switch from xorg to Wayland on Ubuntu 17.10 login isn't the same as mine because their response is that Wayland isn't compatible with the hardware but if I start Wayland session manually before logging in using :
XDG_SESSION_TYPE=wayland dbus-run-session gnome-session
the gnome Wayland session starts fine, my only problem is that I can't find it listed when pressing the gear icon on gdm
