Optimus manager / driver problem

Support Graphics & Display
1

Hello, I have Dell Inspiron laptop with optimus technology. When I was using a 5.4 kernel, optimus-manager worked very well. Only after one update I started to have problems, signaled like this:

[ 324.924574] pci 0000:08:00.0: can’t change power state from D3cold to D0 (config space inaccessible)
[ 324.927735] pci 0000:08:00.0: can’t change power state from D3cold to D0 (config space inaccessible)
[ 324.946387] pci 0000:08:00.0: can’t change power state from D3cold to D0 (config space inaccessible)

Now I’m using a 5.7 kernel and the problem persists. I don’t know if closed nvidia drivers (418.xxx) or optimus-manager are to blame. An interesting fact is that this problem occurs randomly. Specification of my equipment:

This is might be problematic, no driver is loaded for the nvidia gpu. Please run sudo mhwd -li and lspci -k.

Because I was using Intel driver. When I switched to Nvidia, output of inxi looks that:

Device-2: NVIDIA GK208BM [GeForce 920M] driver: nvidia v: 418.113

Can you identify which device is at this PCI address?

5

Yes:

08:00.0 3D controller: NVIDIA Corporation GK208BM [GeForce 920M] (rev ff)
Kernel modules: nouveau, nvidia_drm, nvidia

What are the symptoms of the problem? You cannot suspend or resume? Does it happen in the intel or nvidia mode?

8

This text is an output of dmesg. If it appears, I can’t switch gpu to nvidia. It ioccurs randomly.

9

On kernel 5.8 the problem persists, but the fps rate drops by half. Is it possible for the system not to remove kernel 5.7 after each update?

Now I am using the prime method and the problem is gone. Especially on the new 5.10 kernel there was the biggest problem with switching. It turns out that the optimus-manager was to blame. Unfortunately, switching to prime reduced battery life. Subject to be closed.
