The messages here are mostly in German, but I’ll try to translate mist of it:

I really hope someone can help me out here…

EDIT: I kinda forgot to actually mention my problem. When booting nornall, I get stuck at a lonely white blinking cursor on a black screen, so startx seems to make some problems. I enter a TTY and run startx and this is what I get when running startx:

output of startx

SOLUTION

  • Uninstall your current nvidia driver (for example using sudo apt remove nvidia-driver on Debian)
  • Install the headers for your kernel. your kernel you can check rather easily by running neofetch
  • Install the headers required for your kernel. Do that by listing all packages with your kernel name in it. For example like this: apt list *6.9.7+bpo*
  • reboot, install your nvidia driver again and rovoot again. Should be done.

    You left out the NVIDIA card part. This is super important. So you have two kernels in a bad state and the NVIDIA driver is probably not building out.

    You’ve got a chicken and egg issue.

    This isn’t a technical answer but simply a generalization of what probably needs to happen.

    I would start over on whatever kernel situation you have going.

    First uninstall the NVIDIA driver.

    Then remove that unsigned kernel and its headers. Use the force option if necessary.

    Ensure dkms, the base kernel and its headers are installed.

    Reboot using standard kernel and then install nvidia-dkms package. Reboot.

    It’s tough to tell you exactly what needs to be done because I’m not really sure what kind of damage you did or what the full extent of the errors are. You might need some force options or whatever but generally that’s all that needs to happen. YOU do not have a NVIDIA driver built for whatever kernel you’re using.

      You were entirely correct. Thank you very much for your response, I really was missing the header files for the kernel so the driver couldn’t interact with the system (as far as I can tell). The nouveau driver automatically kicked in on first reboot after installing the header files and I’m now downloading the dkms package again (using Gnome).

        Great!

        If you do fix it, go ahead and update the post with the solution. Help out the next guy.
