OK. Since the problem seems to be in the Nvidia-415 driver, and that driver is not part of Ubuntu then this bug is not a valid Ubuntu bug right now. Sorry.
You can potentially make this a valid Ubuntu bug if you install (downgrade) to a supported version of the Nvidia driver like version 390. 1. Uninstall the nvidia driver version 415. 2. sudo apt install nvidia-driver-390 Then if the bug still occurs in a supported version of the driver we can reopen this bug. ** Package changed: gnome-shell (Ubuntu) => ubuntu ** Changed in: ubuntu Status: Incomplete => Invalid ** Summary changed: - [nvidia] gnome-shell eats 100% cpu when seconds display is on and screen is locked + [nvidia-415] gnome-shell eats 100% cpu when seconds display is on and screen is locked -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814125 Title: [nvidia-415] gnome-shell eats 100% cpu when seconds display is on and screen is locked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1814125/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
