after each kernel upgrade, when I reboot I only get a blank screen

it looks like the proprietary nvidia kernel modules do not get auto recompiled

I have to boot into recovery mode and do dpkg-reconfigure nvidia-dkms-415

and after that all good till the next upgrade.

I guess something get messed up in the system, originaly I tried to install the nvidia driver from nvidia, but ended up removing it and just used the ubuntu one.

any tips how to sort out my system? i don't want to reinstall.

updates :

sudo dkms status:
Error! Could not locate dkms.conf file.
File: does not exist.

ls /var/lib/dkms
dkms_dbversion nvidia

ls /var/lib/dkms/nvidia/

sudo apt purge 'nvidia.*'
sudo apt install nvidia-driver-415

  • Where did you get nvidia-dkms-415. There is no such package in Ubuntu repos. It must be from some PPA. – Pilot6 Mar 2 at 14:57
  • i'm using this ppa:graphics-drivers/ppa – s.illes79 Mar 2 at 15:04
  • Please edit your question and add output of dkms status. – Pilot6 Mar 2 at 15:04
  • And also ls /var/lib/dkms – Pilot6 Mar 2 at 15:05
  • updated original post. dkms.conf is missing, how do i get it? I don't have it on my laptop either, but that has just intel gpu – s.illes79 Mar 2 at 15:30

Your dkms is broken. I suggest to fix it this way:

sudo rm -r /var/lib/dkms/nvidia
sudo apt install --reinstall dkms
sudo apt purge 'nvidia.*'
sudo apt install nvidia-driver-415

That will cleanup the dkms directory, create dkms.conf and install the driver properly.

  • thanks, i did that, now it'm getting: sudo dkms status no output and ls /var/lib/dkms dkms_dbversion – s.illes79 Mar 2 at 15:42

    You should have dkms.conf now and a module installed in dkms status. – Pilot6 Mar 2 at 15:44
  • Please run sudo apt purge 'nvidia.*', then run sudo apt install nvidia-driver-415 and post the output of the second command TO YOUR QUESTION. – Pilot6 Mar 2 at 15:47
  • i think this did it: sudo dkms status nvidia, 415.27, 4.15.0-45-generic, x86_64: installed – s.illes79 Mar 2 at 17:57
  • That looks good. BTW you don't need sudo for dkms status. – Pilot6 Mar 2 at 18:01
