I can't fully read your crash file but can see enough to tell that your gnome-shell crashed in libgtop-2.0.so.11, which means that bug is in an extension you have installed. Likely one of the "system monitor" extensions caused that crash:
GsettingsChanges: b'org.gnome.shell' b'enabled-extensions' b"['[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]']" So this is a bug in: gnome-shell-extension-system-monitor (or similar) Please uninstall the system monitoring extensions and any others you don't absolutely need. Next time you have a crash file please try reporting it by running: ubuntu-bug YOURFILE.crash And if that doesn't work then try some of the steps here: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment Another thing worth noting is that your nouveau kernel driver is crashing occasionally, which doesn't help. Try installing package 'nvidia-driver-390' for a more stable system. Or if you don't need the Nvidia GPU at all then consider disabling it in your BIOS. ** Package changed: gnome-shell (Ubuntu) => gnome-shell-extension- system-monitor (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1778796 Title: Computer freezes on resume (after lock or suspend) Status in gnome-shell-extension-system-monitor package in Ubuntu: New Bug description: Complete freeze on resume (after lock or suspend), excepted that keyboard lights are responsive (e.g. NumLock is operational). No tty available (e.g. Ctrl+Alt+F6 does nothing). Sometimes the freeze lasts for 2-3 minutes, sometimes more and thus I need to force a manual power-off. I suspect gnome-shell to be the culprit here, since it often appears a few minutes later in a "Ubuntu crash" popup. I have this file: /var/crash/_usr_bin_gnome-shell.1000.crash ...but it's 312 MB which seems too large to upload here.
