I am affected by this bug, too. Using an nVidia GTX 660 with legacy nvidia-340 (both mainline as well as graphics-driver ppa) my system is working as before. Switching to 390 or even 396 leaves me at a blinking cursor DM both on sddm and gdm3. The only DM I could use has been lightdm but only after I chowned the .Xauthority file of my user home dir whilst it was running (sadly this is a no go for me as I rely on multi user sessions which do not work anymore since the upgrade to bionic).
