Ubuntu keeps multiple kernel versions installed as a safety fallback. And also each DKMS driver like nvidia should get rebuilt for each kernel that's installed. Although sometimes that step fails, which might explain this bug...
Please reproduce the issue again so we can get a system log of it. Then reboot and run: journalctl -b-1 > prevboot.txt and attach the resulting text file here. ** Package changed: xorg (Ubuntu) => nvidia-graphics-drivers-525 (Ubuntu) ** Changed in: nvidia-graphics-drivers-525 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2020660 Title: Xorg freeze after selecting Nvidia driver v525 (instead of v515) Status in nvidia-graphics-drivers-525 package in Ubuntu: Incomplete Bug description: In the updates manager, after selecting 'Nvidia driver v525' (instead of v515), rebooting does not makes GDM work any more (I can not get the login screen).
