no screen, no keyboard, no mouse, high cpu usage

[Penna Panna]

I have just switched to the last (dynamic) workspace and a half minute later computer froze. It didn't reacted to any keyboard and mouse events, laptop lid closing (I hoped I can suspend) or HDMI cable un/plug (it sometimes used to solve some freezes). That's all I know.

(I have reported the bug in gnome-shell.)

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

The same today. I just browsed some pages on the Internet and... BOOM. Unfortunately, I can't provide any details because I always have to unplug the cable from the power outlet. (I don't see any HD activity - as I remember - so I don't think it's because of out of memory.)

I don't know what happened to Ubuntu 17.10 but it has became very unstable since the update. Can it be my fault? What should I do? Should I do a clean installation? Any suggestions?

Thank you for taking the time to report this bug and helping to make Ubuntu better. A freeze or black screen often means something has crashed. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'.

This bug has occurred three times today for me. It seems that the computer "only" refuses to update the screen and doesn't respond to mouse, keyboard and other inputs, but it's working in the background.
