I have recently started using Kupfer again as my application launcher in Ubuntu MATE, and I found it lacked the ability to suspend the computer.
Here is the plugin I wrote to support this.
To install it, quit Kupfer, create a directory in your home dir called .local/share/kupfer/plugins, and create this file suspend.py inside:
__kupfer_name__ = _("Power management") __kupfer_sources__ = ("PowerManagementItemsSource", ) __description__ = _("Actions to suspend the computer") __version__ = "2021-05-05" __author__ = "Andy Balaam
" from kupfer.plugin import session_support as support class Suspend (support.CommandLeaf): def __init__(self, commands): support.CommandLeaf.__init__(self, commands, "Suspend") def get_description(self): return _("Suspend the computer") def get_icon_name(self): return "system-suspend" class PowerManagementItemsSource (support.CommonSource): def __init__(self): support.CommonSource.__init__(self, _("Power management")) def get_items(self): return (Suspend((["systemctl", "suspend"],)),) # Copyright 2021 Andy Balaam, released under the MIT license.
Now restart Kupfer, go to Preferences, Plugins, and tick “Power management”.
You should now see a “Suspend” item if you search for it in the Kupfer interface.
