gnome-shell-extension-caffeine 35-3 (riscv64 binary) in ubuntu groovy

 This GNOME Shell extension provides an icon which can be toggled to
 inhibit the actions that would normally be taken when the system is idle,
 including screen locking, screensaver and automatic suspend. By default
 it also inhibits idle actions while any window is full-screen, and it can
 be configured to inhibit idle actions while user-specified applications
 have any window open.
 .
 Please note that each user will need to enable the extension manually, for
 example using the gnome-shell-extension-prefs application.
