Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
Xorg crashes when using nvidia-driver-390 with secure boot disabled
Status in nvidia-graphics-drivers-390 package in Ubuntu:
Incomplete
Bug description:
The latest nvidia update causes X.org to crash as soon as I try to
login with gdm. I can login to Wayland for a few minutes but it then
crashes as well. While going through dmesg I saw the following. It
appears that the crash is happening because I disabled UEFI secure
boot. Once I reenabled it the system become stable and I can now use
X.org or Wayland.
