FYI, after a kernel upgrade the NVIDIA driver was unusable again. This time was because of the DKMS mechanism which, for whatever reason I didn't investigate yet (could it be because of the apt-pinning??), didn't success to build and install the nvidia_304.ko module for the new kernel.
If that happens to you, the solution is to run these commands: dpkg-reconfigure nvidia-304 service lightdm restart (no need to reboot) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639180 Title: no login possible after update to nvidia 304.132 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+bug/1639180/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
