Thank you both for your instructions. I have followed the exact instructions as proposed by Oli and have managed to successfully install and load the nvidia driver.
However, apparently I am now stuck in an X session instead of the Wayland session I had before. I have followed the additional instruction here https://wiki.debian.org/NvidiaGraphicsDrivers#Debian_12_.22Bookworm.22 and have run the command: echo "options nvidia-drm modeset=1" >> /etc/modprobe.d/nvidia- options.conf and now, cat /sys/module/nvidia_drm/parameters/modeset, outputs: Y My laptop has both and integrated card and the Nvidia card. I have read the instructions here: https://wiki.debian.org/NVIDIA%20Optimus#PRIMEOffload I don't really understand the second paragraph there, where it says that it should just work out of the box but also recommends some additional steps. Should I uninstall the xserver-xorg-video-intel package as suggested there? Should I be getting an option to select Wayland instead of Xorg at login? I'm not sure I had that option before. I am only using my laptop's screen right now, thank you very much,
