To make Guake start automatically at login, you can add it to the startup applications. In Kubuntu, you can do this by:
Opening the System Settings
Navigating to "Startup and Shutdown"
Selecting "Autostart"
Clicking "Add Program" or "Add Script"
Searching for "Guake" or entering the command "guake"

Guake.desktop

If the above method doesn't work, you can try creating a .desktop file in the autostart directory.

Create a file named guake.desktop in ~/.config/autostart/ Directory with the following content:

• If directory ~/config/autostart does not exist create one mkdir ~/.config/autostart

$EDITOR ~/.config/autostart/guake.desktop

[Desktop Entry]
Type=Application
Exec=guake
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=Guake
Comment=Start Guake Terminal

Guake.desktop file disappering after reboot problem

The issue you're experiencing with the guake.desktop file disappearing from the ~/.config/autostart directory after reboot is a known behavior in some Ubuntu MATE versions, including 24.04.

This happens because certain applications, including Guake, manage their own autostart entries.

To resolve this issue and ensure Guake starts automatically, you can try the following workaround:

Create the guake.desktop file in ~/.config/autostart as you've been doing.

After creating the file, rename it to something like "start_guake.desktop" This prevents Guake from recognizing it as its own file and removing it.
