Thanks. The last messages in that log from ubuntu-appindicators may be related as it has caused bugs like this before.
Please: 1. sudo apt install gnome-shell-extension-prefs 2. Open the Extensions app 3. Disable Ubuntu AppIndicators 4. Log in again If that doesn't solve it then maybe also try disabling the other extensions in the same way. -- 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/1974054 Title: Without a reason gnome-shell CPU usage gets high Status in gnome-shell package in Ubuntu: Incomplete Bug description: Without a reason, CPU usage for gnome-shell jumps from 4% to 22%. All I did this normal workflow, locking/unlocking multiple times over few hours and couple of suspends. The screenshot is showing 37% because of the screenshot tool, but idling at 22%.
