Hi,
    Having secureboot in the bios set to "Windows Mode" I have manually signed the nvidia drivers after uninstalling akmod-nvidia and kmod-nvidia and all the associated packages.
    I then:
             generated a signing key using kmodgenca
            ran mokutil to import the generated key
            rebooted
            And at the MOK Manager interface I enrolled the key and rebooted again
            Then once in KDE I reinstalled akmod-nvidia and kmod-nvidia
            I then ran lsmod | grep -i nvidia
            Does the following display from lsmod indicate that the nvidia module has not installed properly? I don't have the drm module and the blacklisting of nouveau and the nvidia modeset parameter have not been added to the kernel parameters in /etc/default/grub, or is it that I did not force a rebuild of the kernel module and I did not force an update of the boot image?

lsmod | grep -i nvidia
nvidia_drm             73728  32
nvidia_modeset       1187840  65 nvidia_drm
nvidia_uvm           1318912  0
nvidia              55242752  2950 nvidia_uvm,nvidia_modeset

regards,
Steve
