I tested this in a VM using the default xenial cloud image (ie. "uvt-kvm create xenialoem release=xenial").
With the current nvidia-384 384.90-0ubuntu0.16.04.2 package, the nvidia dkms module doesn't get built after the reboot: $ sudo apt update $ sudo touch /tmp/do_not_build_dkms_module $ sudo apt install nvidia-384 $ dkms status bbswitch, 0.8, 4.4.0-103-generic, x86_64: installed $ sudo reboot $ dkms status bbswitch, 0.8, 4.4.0-103-generic, x86_64: installed With the new nvidia-384 384.90-0ubuntu0.16.04.3 package, the nvidia dkms module DOES get built after the reboot: $ sudo apt update $ sudo touch /tmp/do_not_build_dkms_module $ sudo vi /etc/apt/sources.list # adding xenial-proposed $ sudo apt update $ sudo apt install nvidia-384 $ dkms status bbswitch, 0.8, 4.4.0-103-generic, x86_64: installed $ sudo reboot $ dkms status bbswitch, 0.8, 4.4.0-103-generic, x86_64: installed nvidia-384, 384.90: added ubuntu@xenialoem:~$ grep -i dkms /var/log/syslog Dec 15 20:39:00 xenialoem sh[1057]: Creating symlink /var/lib/dkms/nvidia-384/384.90/source -> Dec 15 20:39:00 xenialoem sh[1057]: DKMS: add completed.

I am waiting to get more details. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1732206 Title: nvidia-graphics-drivers deferred DKMS feature does not work in xenial To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1732206/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
