It sounds like you have run out of memory or some other resource. Next time the problem happens, please:

1. Wait 10 seconds.

2. Reboot.

3. Run:

   journalctl -b-1 > prevboot.txt

4. Attach the resulting text file here.

here is the prevboot file

That log is only 42 minutes long. Are you sure the bug occurred in that time?

[Brady Williams (thblwill)]

there was a an update for the nvidia driver and a system update that I did today. after the update I rebooted the system and then 42 minutes later it chrashed

[Daniel van Vugt (vanvugt)]

It appears 'whoopsie' might be trying to report a crash but it can't reach the Ubuntu servers. Please try following these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment

[Brady Williams (thblwill)]

there was no crash file, but there is a whoopsie file. Although, when I go to https://errors.ubuntu.com/user/ID there is nothing. i have done the work around and will wait for it to crash again.

[Daniel van Vugt (vanvugt)]

If there is no evidence of a crash and nothing else in the system log then I would guess it to be a catastrophic failure in the Nvidia kernel driver :(

Maybe try Nvidia driver version 495 in the 'Additional Drivers' app?

[Brady Williams (thblwill)]

thank you for your help with this. It seems that it was not a problem with Ubuntu, but a driver issue. Once I changed to the Nvidia 495 drive I have not had any problems.
