Ctrl-x x not recognised in Ubuntu 22.04

Ctrl-x x not recognised in Ubuntu 22.04

[Bill Purvis]

Hi, I've just upgraded to Ubuntu 22.04 (as 21.10 is now out of support) 
and find that when I type 'ctrl-x x'
is says 'C-x x is undefined' I have been using 'C-x x t' to enable line 
truncation, it worked fine with
21.10, but now in 22.04 I can't do it.

C-h k also says C-x x is undefined.

Has something changed?

Bill

Which Emacs version do you have there?

That's the problem: "C-x x t" appeared in Emacs 28.

No clue.  I don't use Ubuntu.

M-x toggle-truncate-lines RET

OK, I've managed to compile and install 28.1, working fine.
