I am trying to install the Nvidia driver on my Dell XPS 9550 fresh Debian 12 machine.
I followed all instructions in https://wiki.debian.org/NvidiaGraphicsDrivers#Debian_12_.22Bookworm.22 including: apt install linux-headers-amd64 Including the extra instructions given here: https://lists.debian.org/debian-user/2025/01/msg00121.html To enroll the MOK key. Then added the additional source to apt list and did: apt install nvidia-driver firmware-misc-nonfree After rebooting the nvidia driver is not loaded and some errors are presented by dmesg: $ sudo dmesg | grep modul [ 4.313816] systemd[1]: Inserted module 'autofs4' [ 4.586851] systemd[1]: Starting systemd-modules-load.service - Load Kernel Modules... [ 4.590723] loop: module loaded [ 5.621417] Loading of module with unavailable key is rejected [ 5.646333] Loading of module with unavailable key is rejected ...

Getting Debian to work in this laptop has been a big challenge. thank you, Anil F
