I'm thinking bug 784055 is a large part of the problem here. And I am guessing that if you follow the instructions in comment #2 then you might have experienced bug 1880405 which still randomly affects Ubuntu 20.04.
If no further information is added here then this bug will close automatically after 60 days. But please also uninstall indicator- multiload while testing for additional CPU hogs. -- 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/1928791 Title: gnome-shell runs on 60--100% CPU usage Status in gnome-shell package in Ubuntu: Incomplete Bug description: from top output: top - 14:18:02 up 5:45, 1 user, load average: 1,55, 1,54, 1,77 Tasks: 419 total, 1 running, 418 sleeping, 0 stopped, 0 zombie %Cpu(s): 13,2 us, 2,6 sy, 0,0 ni, 83,7 id, 0,1 wa, 0,0 hi, 0,4 si, 0,0 st MiB Mem : 7960,7 total, 233,0 free, 5719,6 used, 2008,1 buff/cache MiB Swap: 26058,0 total, 23596,0 free, 2462,0 used. 576,0 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 20866 tobias 20 0 6652668 996,0m 83472 S 63,4 12,5 33:56.49 gnome-shell this is so wrong… how to fix it? best, Tobias ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gnome-shell 3.36.7-0ubuntu0.20.04.1 ProcVersionSignature: Ubuntu 5.8.0-53.60~20.04.1-generic 5.8.18 Uname: Linux 5.8.0-53-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.17 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Tue May 18 14:11:41 2021 DisplayManager: gdm3 InstallationDate: Installed on 2020-07-22 (300 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) RelatedPackageVersions: mutter-common 3.36.7+git20201123-0.20.04.1 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1928791/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
