Interesting results for the first two commands (I don’t know if dmesg | tail -50 is supposed to be a command or what modprobe nvidia could output). This was done both without and with the DGPU active (Integrated & Hybrid)
sudo modprobe nvidia
[sudo] password for root:
modprobe: FATAL: Module nvidia not found in directory /usr/lib/modules/6.18.6-1.0.4.sr20260101-default
dmesg | tail -50
dmesg: read kernel buffer failed: Operation not permitted
mokutil --sb-state
SecureBoot disabled
I do recall disabling SecureBoot, or at least SecureBoot Control in BIOS when first setting up asusctl and supergfxctl .
An additional note regarding my issue, it seems whenever I shut down and power on, I always default to Integrated mode, instead of what mode I shut down my laptop on.
There is no NVIDIA kernel module built for the running kernel.
Yes, it is a (diagnostic message) command used to display kernel message output. It needs elevated privileges to run, hence you needed to use sudo.
I see, here is dmesg | tail -50 after using sudo

At this point dmesg output isn’t going to add anything useful. We already know the NVIDIA kernel module doesn’t exist for the running kernel.
The running kernel is 6.18.6-1.0.4.sr20260101-default and the installed NVIDIA KMP is
nvidia-driver-G06-kmp-default | package | 580.126.09_k6.18.4_1-44.2
If kernel 6.18.4 is still installed, you could try booting it from the GRUB menu.
Otherwise see what NVIDIA KMP builds are available…zypper se -s nvidia-driver-G06-kmp-default
What should I be doing at this point? Sorry, I’m still not savvy when it comes to debugging all this.
I think the Tumbleweed Nvidia repo is in use…

So, unless there is a specific problem with the Slowroll kernel, force-reinstalling the Nvidia kmp might help.

Tested it for awhile, this seems to have fixed it! Supergfxctl is working normally again!

Thanks for the update. Good to read that the driver version is now matching the kernel, and working as expected. Issues like this help you learn how it all hangs together.
