I solved the keyboard shortcut problem with Guake by using Xorg instead of Wayland as a Windows display manager.
However, whenever I lock the screen (Ubuntu 23.04), then return, Guake needs to be rebooted with nohup guake &
, then it works again (and with the dropdown keyboard shortcuts).
What is the reason for this? As a fix, can I auto-run this command on screen unlock? Or something to fix this?
