After updating my system and rebooting, I tried to launch NVIDIA X Server Settings to see if my driver had updated properly. It did not show any Nvidia driver installed, and sudo lshw -c display outputted

I blacklisted nouveau in /etc/modprobe.d/blacklist.conf:
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off
and updated initramfs but lshw still showed nouveau after rebooting. I also tried uninstalling xserver-xorg-video-nouveau but weirdly this did nothing. I also ran sudo ubuntu-drivers autoinstall but it did not install anything.
I was able to get the proprietary Nvidia drivers running only by booting into kernel 4.15.0-23-generic. Is it possible to get proprietarry drivers to work on -33?
EDIT: X11 seems to restart when using nouveau and launching certain applications. Tilix, Firefox, Steam, Discord, Nautilus and System Monitor seem to work, but all (tested) settings applications seem to cause the restart. Will update after testing more apps
EDIT 2: More testing showed that only settigns applications seem to cause the restart. This includes Display Preferences, System Settings, Budgie Desktop Settings, but not NVIDIA X Server Settings. I should also add that the restart brings me back to the login menu, not to the desktop.
EDIT 3: I fixed it! I had to reinstall my kernel with sudo apt install --reinstall linux-image-4.15.0-33-generic and lshw shows the Nvidia driver in use.
