After upgrading linux kernel, I have to reinstall nvidia-driver. Otherwise, the display will not use GPU.

Now I need to do the following manaully after the kernel is updated

sudo apt remove nvidia-driver-396
sudo apt autoremove
sudo apt install nvidia-driver-396

Here is the system info

➜  ~ cat /etc/lsb-release                                     
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

And the GPU card

➜  ~ nvidia-smi

dkms status outputs some strange error

➜  coqa_rnet git:(master) ✗ dkms status     
anbox, 1, 4.15.0-33-generic, x86_64: installedError! Could not locate dkms.conf file.
File:  does not exist.

anbox, 1, 4.15.0-34-generic, x86_64: installed

Am I missing any configuration for the module?

Thank you!

  • What does dkms status return? Could you add that to your question? Thank you! – Terrance Sep 12 '18 at 14:15
  • @Terrance I added dkms status output, I guess there might be configuration overwrite in my machine. – Vimos Sep 13 '18 at 07:21

    Ah, yep. Try running sudo apt install nvidia-dkms-396 and then run the dkms status after that. If the driver appears, then you should be good to go after that. However, I am not sure about the anbox error you see there. You can try this answer for the missing dkms.conf file: https://askubuntu.com/a/636913/231142 – Terrance Sep 13 '18 at 13:27
  • @Terrance The link you shared helped me! I removed anbox and dkms status no more complains. I will wait for the next kernel update to see if nvidia is OK. Thank you! – Vimos Sep 14 '18 at 06:24
