I'm afraid logging in blindly and then run "xrandr --auto" in an automatically Xsession startup would crash the Xserver the same way. :-( Easiest for now would be to switch to suse-prime's "offload" mode via prime-select offload https://github.com/openSUSE/SUSEPrime#installationusage https://download.nvidia.com/XFree86/Linux-x86_64/435.21/README/primerenderoffload.html or to get rid of nvidia drivers completely. Then you can remove suse-prime as well.
