BTW, your setup (xorg.conf.d snippet) is nothing we can support. Maybe you can use suse-prime instead, i.e. run 'prime-select' after installing it (if package not installed yet). JFYI, nouveau driver is already blacklisted when using our nvidia KMP. Also modeset is turned on. I'm not sure about the consequences of using 'security=apparmor'. I never tried this with the nvidia driver.
