GNU emacs on Ubuntu 14.04 LTS

[Alexandre Oberlin]

Hello,

I cannot manage to bind ctrl+home/ctrl+end to beginning/end-of-buffer in  
Ubuntu 14.04 LTS.
Event doing it interactively does not work. Instead of "ctrl+home", I get  
"home" in command-history:
(global-set-key (quote [home]) (quote beginning-of-buffer))

It’s emacs 23.4. I don’t want the whole cua stuff.


Cheers

Use C-h l (view-lossage) to see what keypresses emacs detects.
You should see <C-home>.

Thanks for this fancy tip! I’ll try when back on Ubuntu.

This is C-b followed by 3 times <home>, then C-b followed by 3 times <C-home>

C-b ESC O H ESC O H ESC O H C-b ESC O H ESC O H ESC O H 

<home> and <C-home> appear the same to emacs.

Looks like you are running Emacs in a terminal.

To distinguish home and C-home you would need to configure or
modify the terminal emulator.

Running Emacs under X will change things.

Yes, you are right, X was unavailable because of this:
With the coming 14.04 release sux (wrapper around su which will transfer your X credentials) is no longer included in Ubuntu. (I think it is being removed because it is being pulled from Debian, because of no maintenance of the original code.)
source http://askubuntu.com/questions/428284/what-is-a-good-alternative-to-the-sux-command where an alternative to using the obsoleted sux is given. 
The problem is then solved, thanks.

For a while, I was stuck running Emacs in a terminal.
I usually use rxvt.
In a couple of cases, I modified the source to get unique escape
sequences for odd key combinations.

Now I run under X which is a more sane way to go.

I know you said you already solved this but let me comment for the
archive.  I have these bindings and they work in the terminal.

  (global-set-key [home] 'beginning-of-buffer)
  (global-set-key [S-home] 'end-of-buffer)
  (global-set-key [end] 'end-of-buffer)
  (global-set-key [S-end] 'beginning-of-buffer)

Rather than using sux or some other method to run the entire Emacs as
another user like root, try Tramp mode:

C-x C-f /sudo::/etc/whatever-you-want

That way, your Emacs session runs as you, and only the bare minimum
needed for root permissions is using sudo.  (You can also do
"/su::/etc/whatever" if you're on a machine with a real root account.)
