Ubuntu 19.04 high cpu use

  • 772

I have high cpu use in Ubuntu 19.04, and my screen seems laggy.

Watching top I see gnome-shell running about 50% very often.

cpu-load gnome-shell 19.04

  1. The new version of gnome-shell is not compatible with some extensions. In particular those trying to show systray, such as "TopIcons Plus" are not working well.

    Disable extensions (one-by-one?) to see if this reduces CPU usage.

    To do this, install the gnome-tweaks package.

    Open tweaks, check the extensions tab on the left, and disable extensions on the right (shown below, POP_OS, but should be similar/identical in other flavors of Ubuntu):

    An alternative to TopIcons Plus which seems to catch most of the systray devices is "KStatusNotifierItem/AppIndicator Support"
