Why is suspend-emacs enabled at all in GUI mode?

I already have the C-z binding disabled. But I was debugging a problem with my init file which hadn't loaded completely, had the problem halfway solved but then accidentally suspended the Emacs GUI. Now I have to restart Emacs and redo that work for no good reason. Being able to suspend Emacs from a terminal makes sense, but why does this feature exist at all when running it in a GUI? If anything, it seems like some kind of practical joke. There doesn't seem to be any way to recover the previous state of the program. I already tried all the suggestions on [this page](https://superuser.com/questions/349943/how-to-awake-emacs-gui-after-pressing-ctrlz). I'm sure I can't be the first to complain about this. Would a bug report be a waste of time? EDIT: I meant `suspend-frame` (can't edit titles on Reddit). EDIT2 (Update): It's only the Emacs master-branch which I compile from the git-cloned source that becomes completely unresponsive. If I'm using Emacs 28.1 on the same desktop/OS and press C-z, it merely iconifies the frame.

I also click it sometimes, I just move the focus to another window and back and the suspend is gone. I'm on i3.

It's been a really long time since I've had a workflow like this, but IIRC it used to iconify the current frame. I also have it disabled.

To be precise it actually invokes `suspend-frame`: https://github.com/emacs-mirror/emacs/blob/master/etc/NEWS.23#L1007-L1008 Personally I just rebind it as a shortcut for `C-x 5`.

Cannot reproduce: when I press C-z in GUI mode, it merely minimizes/iconifies the frame. Just tried with "emacs -q" to make sure nothing in my config was affecting it, and sure enough, it still just minimized.

It may be something to do with how it interacts with KDE. IIRC, what you describe is what would happen when I used Gnome.

I think when I used Gnome it acted that way, but ever since switching to KDE I can't bring it back afterwards. I can bring the window back up, but it's completely unresponsive. Same thing if I start Emacs with `emacs -Q` and press C-z. EDIT: If I run Emacs on Gnome in a Debian VM, I can C-z and focus the frame again, and continue using Emacs. Not so on my Fedora Kinoite desktop. Hmm.

That sounds like a bug, honestly. Use `M-x report-emacs-bug` to send in a bug report.

I just rebound C-z to undo and called it a day.

I reckon this must be one of the biggest discouragements for emacs newbies. "I typed something but made a mistake and hit \^z and the whole thing locked up. Had to kill emacs and I lost everything"
