> 4) What happened instead

Can't disable input methods.
On Ubuntu 15.04, I can disable input methods this way.
This poses a problem for C-space on emacs -nw.

I think this is a regression bug because I can avoid this problem by using Ubuntu 15.04 version of /usr/bin/gnome-terminal script. The most important difference between older and newer /usr/bin/gnome-terminal is:

< if not cmdargs.disable_factory and cmdargs.cls is not None:
< if self.name is not None:
< self.args.append('--app-id=%s' % self.name)
---
> if not cmdargs.disable_factory and self.name is None:
> sys.exit(subprocess.call(self.args))

If I change these lines back, I can disable input methods.

The attachment is workaround for /usr/bin/gnome-terminal.
I'm not sure why this works, but I hope this helps developers.

Could you please launch the "cat" command and then press Ctrl-space? What do you see without touching the input method, and with touching it plus your patch? The expected behavior is ^@ to appear.

Hi Egmont, thank you for response.

The input method turns on.
