/proc/cmdline has existed for a long time (>25 years). It shows what the active kernel command line is for the current boot. It is the source of truth of how the kernel was last booted. The new kernel install always takes one of the boot lines and uses that exact line for the newly installed kernel.

Is that a change with the 6.0.5 kernel, prior to that kernel they were always in /etc/default/grub? > Just looking at grub.cfg I have now found that while I thought I was boot off the 6.0.5 kernel, I hadn't actually run grub2-mkconfig to update grub.cfg for the new kernel. I have run that now and because /etc/default/grub no longer has the nouveau blacklisting statements they are not supplied on the kernel line in grub.cfg for any kernels it's set up to boot from. From below /proc/cmdline has also not been updated for the 6.0.5 kernel either, I'll see what it shows when I get a chance to boot off that kernel. > > cat /proc/cmdline > BOOT_IMAGE=/vmlinuz-5.19.16-200.fc36.x86_64 root=UUID=ba36dde9-5bf1-4140-89e7-b82ee1fe7cf9 ro rootflags=subvol=Fedora_root rhgb quiet rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 > > regards, > Steve > > > On Mon, Oct 31, 2022 at 2:53 AM Stephen Morris <samorris@xxxxxxxxxxxxxxx> wrote: > > On 31/10/22 13:48, Samuel Sieb wrote: > > On 10/30/22 19:26, Stephen Morris wrote: > > On 31/10/22 09:12, Samuel Sieb wrote: > > On 10/30/22 14:54, Stephen Morris wrote: > > I then ran lsmod | grep -i nvidia > Does the following display from lsmod indicate that > the nvidia module has not installed properly?
