I have a problem with the nvidia driver on my Ubuntu 22.04.5 running linux kernel 6.8.0-45-generic.

  1. I cannot get any sound from my monitors over DisplayPort although bluetooth headsets do work.
  2. When the PC is in suspended, it cannot wake up from suspend state.

I remember that a couple of days ago, running sudo apt update, some nvidia kernel install has failed with errors.

Here is the log file:

Edit:
The following package has been kept back:
gir1.2-mutter-10 libmutter-10-0 linux-modules-nvidia-545-generic-hwe-22.04 mutter-common

If I try to install it, it follows that there are unmet dependencies:

linux-modules-nvidia-545-6.5.0-28-generic : Depends: nvidia-kernel-common-545 (>= 545.29.06) but it is not installable
nvidia-dkms-545 : Depends: nvidia-kernel-common-545 (<= 545.29.06-1) but it is not installable
Depends: nvidia-kernel-common-545 (>= 545.29.06) but it is not installable
nvidia-driver-545 : Depends: nvidia-kernel-common-545 (<= 545.29.06-1) but it is not installable
Depends: nvidia-kernel-common-545 (>= 545.29.06) but it is not installable

I could at least fix the sound issue by checking if other driver versions are available with

sudo ubuntu-drivers list

and then installing the most recommend one with

sudo ubuntu-drivers install

The waking of from suspend mode, works somehow now although the GUI is almost black and I can’t actually do anything this way
