After upgrading to Ubuntu 18.04, I can't find xkill
on pressing Alt+F2. Instead it shows a message box with a text-field titled as Enter a Command
.
How can I find xkill
on Ubuntu 18.04 and what is the purpose of this new window?
One Linux keyboard shortcut gives you quick access to all of your software and some useful commands. It’s like a portable command line, and it’s probably already built into your Linux distro of choice. Just hit “Alt” and “F2” at the same time to get started. Whether you want to force-quit a hanging application or quickly launch your favorite text editor, this shortcut is indispensable for Linux users.
Most long-time Linux users are probably already familiar with Linux keyboard shortcuts, but new Linux converts might not have discovered this simple shortcut yet. They should, because once you get used to using it you’ll wonder how you ever lived without it. It’s a great way to quickly launch your favorite applications, and can be used to do much more.
You need to type xkill
in Enter a command
prompt and hit Enter.
Unity used to have this kind of interface when Alt+F2 was used:
That was basically interface for entering a command with label Run a Command
and Not a Dashboard(However it seems to be and that's what you are referring to.). It used to show suggestions as you type.
But in GNOME interface is like this:
And yes this doesn't show any sort of suggestions.
You can either create a Desktop Entry or define a keyboard shortcut in Settings → Devices → Keyboard to use xkill
quickly.
The package involving xkill is x11-utils. If not already installed:
sudo apt install x11-utils
Now press Super+A and type xkill
Enter.
Or set a new keybinding in Settings -> Devices -> Keyboard
Adds a force quit button which launches xkill. On accidental click, right click to undo or click on the panel. Customize position by tweaking line 27 of extension.js
