After ubuntu update to 13.10 guake didn't appear on F12 key. I tried to change it to another F-key, but get message: "Unable to bind global F12 key". Any ideas how to get this to work again?

  • Could tilde configuration be the problem? By default tilda likes to pop up on F12 and it keeps the keycode that starts it in its own configuration file.

In GNOME 3.32, set a manual keybinding of "guake" to F12 in GNOME Settings > Keyboard, and it works!


It was reported like a issue to guake, not seems to be a solution yet:



I know this is an old thread, but turning on the "F Lock" (Function lock?) key made the keybindings for me on an Ubuntu Mate 19.10 desktop with an old Microsoft keyboard.


I had a totally different problem that solved this too:

Search for the file.conf in /etc/gdm3/ in my case, Ubuntu 20, it's custom.conf

sudo nano /etc/gdm3/custom.conf

Uncomment the line


to be


then reboot.
