New OS, new problems. Recently, I wanted to try out Fedora. In my daily work routine, I heavily rely on Guake, the terminal that pops up when a global hotkey is pressed. However, when I started Guake for the first time on Fedora 30, there was an error message saying that it could not bind the global hotkey F12.

This seems to be a known issue. Workarounds are described on GitHub.

The workaround described the latter comment relies on Python 2, which is not available on Fedora 30. The updated instructions are as follows.

Create a file called /usr/bin/guake-toggle.py with the following content.

#!/usr/bin/env python3
import dbus

try:
    bus = dbus.SessionBus()
    remote_object = bus.get_object("org.guake3.RemoteControl",
                                   "/org/guake3/RemoteControl")
    remote_object.show_hide()
except dbus.DBusException:
    pass

Make the script executable. Finally, go to Setting > Devices > Keyboard and add a new hotkey that runs the above script.

If you want Guake to run at startup, go to Guake’s Preferences panel and enable Start Guake at login.

Update: The above solution has also been mentioned on GitHub.
