So when I installed the nvidia-driver package with nvidia-kernel-dkms, everything worked fine but when I switched to nvidia-open-kernel-dkms, Debian 12 wouldn't boot and it would stay on the screen with all the "[ok]"s on it without doing anything, I pressed ctrl+alt+del on that screen to open the terminal and looked at the logs with dmesg with grep "nvidia" and compared that to the logs of a working system with nvidia-kernel-dkms and I noticed these lines weren't there on the working system logs:
[ 17.039871] NVRM: Open nvidia.ko is only ready for use on Data Center GPUs. [ 17.039874] NVRM: To force use of Open nvidia.ko on other GPUs, see the [ 17.039874] NVRM: ‘OpenRmEnableUnsupportedGpus’ kernel module parameter described [ 17.039875] NVRM: in the README. I then typed this command I found online: echo "options nvidia NVreg_OpenRmEnableUnsupportedGpus=1" | sudo tee /etc/modprobe.d/nvidia-openpm.conf to force the use of open nvidia.ko on other GPUs than Data Center ones and rebooted the system and everything worked flawlessly. If I believe this line of log: [ 17.039871] NVRM: Open nvidia.ko is only ready for use on Data Center GPUs. The nvidia-open-kernel-dkms package present in debian 12 is still in alpha and is not to be used for now. Maybe this page still holds true: https://us.download.nvidia.com/XFree86/Linux-x86_64/515.43.04/README/kernel_open.html If the nvidia-open-kernel-dkms package is effectively not ready to be used on debian 12, I believe we should modify what this page https://wiki.debian.org/NvidiaGraphicsDrivers says about the "open flavour" of nvidia-kernel-dkms. If you find there is a bit too much pride in this message you're probably right 😅! I'm a linux beginner (little experience on mint) and so I'm pretty proud of myself for finding out what I just explained cause it's my first time debugging a linux related issue 🙃!
