Edit: this seems to be an issue related to Thinkpad laptops

I am working on a fresh install of ubuntu 20.04.

uname -r outputs:

5.6.0-1047-oem

sudo apt upgrade outputs:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following NEW packages will be installed:
  linux-generic-hwe-20.04 linux-headers-5.8.0-43-generic linux-headers-generic-hwe-20.04 linux-hwe-5.8-headers-5.8.0-43
  linux-image-5.8.0-43-generic linux-image-generic-hwe-20.04 linux-modules-5.8.0-43-generic linux-modules-extra-5.8.0-43-generic
  oem-sutton.simon-meta
The following packages will be upgraded: ...

This is a bit obscure to me.

According to: What is hardware enablement (HWE)?, one may use either the generic kernel, or the hwe kernel. But the above seems to be listing both the generic and the hwe kernels to be upgraded. Or it may be I am just confused about what the upgrade does.

The context is that running apt upgrade from that points breaks the nvidia drivers (i.e. before the upgrade nvidia-smi outputs something sensible, after it outputs it can not not communicate with the nvidia drivers). I am trying to figure out the best action to perform.

The following does not answer the question (why both the generic and the HWE kernels are meant to be upgraded), but the following managed to have the nvidia drivers working fine, even after upgrade:

  • disabling secure boot in BIOS
  • installing Ubuntu
  • removing the file oem-sutton.simon-addison-meta.list from /etc/apt/sources.list.d

This file seems to be specific to Lenovo systems.

The nvidia drivers can then be installed.
