No wayland session when using radeon kernel driver
I have an AMD HD 7750 gpu (southern islands generation). On both Arch and Ubuntu 19.04 (which have gnome 3.30), I have no Wayland session to choose from gdm. If I modify my grub and boot with amdgpu kernel driver (which is still experimental for my gpu's generation) then Wayland session appears and works fine. With Ubuntu 18.04 which has gnome 3.28, Wayland session is present and works with both radeon and amdgpu kernel drivers.
