Trouble with Nvidia Driver update

[die.boer]

Those results look very good.
I'd say we can now rule out a currently broken NVIDIA/DKMS setup.

"dkms status" shows:

nvidia/595.91.07, 7.0.0-31-generic, x86_64: installed

so the NVIDIA module has been successfully built and installed for the kernel you're actually running.

"lsmod" also shows the expected NVIDIA modules loaded:

nvidia
nvidia_modeset
nvidia_drm
nvidia_uvm

And most importantly, "nvidia-smi" sees the RTX 4090 correctly and reports:

Driver Version: 595.91.07
CUDA Version: 13.2
NVIDIA GeForce RTX 4090

It is also clearly being used by the desktop and applications — Xorg, KWin, Plasma and Blender are all showing up in the process list.

So I wouldn't change anything on this installation at the moment.

The interesting question remains what happened when 610 was attempted. The current evidence doesn't point to a general NVIDIA, DKMS, or kernel problem. It looks much more like something specific to the 610 installation/update.

I'd therefore keep 595 Open for now, since "ubuntu-drivers" identifies it as the recommended driver, and investigate the 610 transition separately.

In short: the machine is healthy now, and I'd leave the working configuration alone.

OK, thank you.
ATM I always choose advanced boot options in grub to start this kernel.
Not very convinient.

...investigate the 610 transition separately.

Could you help me with that too?

[die.boer]

to be clear , you want to boot into the 7.0.0-31-generic kernel ?
if so please 1st post the output of this :

grep "^GRUB_DEFAULT" /etc/default/grub

[LuisSeyfer]

I thought, since linux-image-7.0.0-2016-nvidia-bos came as an update, I should make this one run again.

grep "^GRUB_DEFAULT" /etc/default/grub
GRUB_DEFAULT=0

I thought, since linux-image-7.0.0-2016-nvidia-bos came as an update, I should make this one run again.

grep "^GRUB_DEFAULT" /etc/default/grub
GRUB_DEFAULT=0

which kernel were you booted in when you ran the command grep "^GRUB_DEFAULT" /etc/default/grub ?
and is everything working fine with that kernel ?

[die.boer]

from your previous output it shows your machine has 2 kernels installed
ii linux-image-7.0.0-31-generic
ii linux-image-7.0.0-2016-nvidia-bos
but the system is currently running 7.0.0-31-generic
And /boot says
initrd.img -> initrd.img-7.0.0-2016-nvidia-bos
vmlinuz -> vmlinuz-7.0.0-2016-nvidia-bos
Those symlinks point to the NVIDIA-BOS kernel, while uname -r says the machine booted the generic kernel.
