Update: Passing ibt=off as a kernel flag resolved it.
TL;DR: After switching from nouveau to nvidia, when I run startx the system locks up and I have to hard reset.
I recently had need of CUDA so I decided to switch from my integrated graphics to dedicated graphics (RTX A3000 Mobile) on my laptop. To support CUDA I also migrated from nouveau to nvidia. I installed the nvidia drivers, then nvidia-utils and nvidia-settings (in that order), blacklisted nouveau (both in modprobe.d and in grub via nouveau.modeset=0. Finally I set nvidia_drm.modeset=1 in grub.cfg (this flag doesn't affect the outcome, but it's currently set). I then rebooted. Once I pass grub it takes several minutes to boot and when I'm finally greeted with a terminal I get a bunch of messages of the form [<some numbers>] audit: <stuff>.
I then built a new xorg.conf using nvidia-xconfig and ran startx -logverbose 6 (this was working with nouveau and integrated graphics). I get the usual splash in the terminal about where the logs are going etc and then the system is unresponsive and I have to hard reset to regain control. There doesn't seem to be anything useful in the x logs, but they are below in case they are of some use.
Without any errors, I'm at a complete loss for how to proceed...I can't even get ctrl+alt+fn to let me switch TTY so I can look at dmesg
