latest xkeyboard-config prevents ctrl-alt-backspace from killing X

flamelab · 2009-05-30 10:28:30

As always, the Ubuntu devs interfered into a big Linux project (like GNOME for example) and created a mess.

Those guys should be banned from connecting to the internet.

karol · 2009-05-30 10:38:21

I don't care if the idea came from Ubuntu, xorg / freedestop or from BillG himself, but I kinda like nice fonts and graphic browsers and don't want to ditch X completely.

vries · 2009-05-30 11:15:24

heh, so backspace is not good enough for xorg devs now, eh? I've created a patch for xkebord-config since I prefer to patch my packages than adding another command to startup scripts.

@vries
The problem w/ patches is that they are pain in the neck to maintain.

I added the setxkbmap line to my ~/.xinitrc but my C-A-Backspace doesn't restart gdm.

$ cat ~/.xinitrc 
#!/bin/sh
exec gnome-session
setxkbmap -option terminate:ctrl_alt_bksp

karol · 2009-05-30 13:44:24

Maybe you should switch the lines - execute setxkbmap first?

graysky · 2009-05-30 13:47:14

@karol - I tried it both ways

#!/bin/sh
exec gnome-session
setxkbmap -option terminate:ctrl_alt_bksp

and also

#!/bin/sh
setxkbmap -option terminate:ctrl_alt_bksp
exec gnome-session

karol · 2009-05-30 13:52:26

Maybe when you're using session manager everything's a bit different because it's handled by xfce4-session or gnome-session. It's just a guess and unfortunately I don't know how to enable C-A-B in your setup.

graysky · 2009-05-30 13:54:58

Thanks for the reply, karol.

Thanks to this thread I've got C-A-Backspace working again, but I can't use Super_L in any shortcuts. I've got the following in my .stumpwmrc and now it does absolutely nothing:

(define-key *top-map* (kbd "M-S-Super_L")   "exec urxvtc -e python")
(define-key *top-map* (kbd "C-Super_L")     "exec urxvtc -e screen")
(define-key *top-map* (kbd "C-S-Super_L")   "exec urxvtc -sh 0 -e cmatrix -C red -l -b")
(define-key *top-map* (kbd "C-M-Super_L")   "exec urxvtc -e guile")
(define-key *top-map* (kbd "C-M-S-Super_L") "exec urxvtc -e clisp")
(define-key *top-map* (kbd "M-Super_L")     "exec urxvtc -e emacs")

karol · 2009-05-30 14:05:06

@Barrucadu
Maybe you should check new features of xkeyboard-config.

Barrucadu · 2009-05-30 14:06:20

Ah, it seems Super_L has transformed into a modkey.

kareeser · 2009-05-30 14:13:23

Hm. Interesting move... I also noticed this happenning.

I figured they already disabled Ctrl-Alt-Bksp already, so what's the point in further disabling it? Sounds like a dick move just to piss off people who like that particular shortcut

Good to hear the solution is simple... I had thought for a moment that I'd done something wrong, since I was in the middle of messing around with my setup.

R00KIE · 2009-05-30 15:40:55

This is going to be the whole mess all over again
How many times is this going to be changed upstream and to what purpose ...

karol · 2009-05-30 15:45:07

Developers can be every bit as good / bad as any people. If politicians can have "fun" making little changes that piss people off but don't really make the world a better place, why the devs can't? I think they _shouldn't_ even if they can but that's another story.

Is anyone running Gnome with this updated version of xorg AND has restored their C+A+Backspace?

vries · 2009-05-30 19:20:32

I've found better way to maintain it:
if you use hotplugging add:
<merge key="input.xkb.options" type="string">terminate:ctrl_alt_bksp</merge>
to your /usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi

if you aren't using hotplugging add:
Option "XkbOptions" "terminate:ctrl_alt_bksp"
to keyboard section in xorg.conf

I use HAL/evdev to auto configure my keyboard. For german keyboard layout I needed to copy /usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi to /etc/hal/fdi/policy/10-keymap.fdi and make some changes.

After adding

<merge key="input.xkb.options" type="string">terminate:ctrl_alt_bksp</merge>

to the file Ctrl+Alt+Backsp works here.

this is my complete /etc/hal/fdi/policy/10-keymap.fdi

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">

    <match key="info.capabilities" contains="input.keymap">

    </match>

    <match key="info.capabilities" contains="input.keys">
      <merge key="input.xkb.rules" type="string">base</merge>

      <!-- If we're using Linux, we use evdev by default (falling back to

Hm.

I wonder if anyone's actually explored the possibility that one could change the "restart X" combo from Ctrl-Alt-Bksp to Ctrl-Alt-Bksp x 2. It would certainly stop people from hitting it accidentally.

Hell, make it a three-fer, and if you STILL manage to hit it by accident, then you're just an idiot.

Edit: As it turns out, yes, it's been discussed, but glossed over without much discussion. Too bad.

I can execute the following command to re-enable the C+A+B restarting X once I'm logged into gnome:

$ setxkbmap -option terminate:ctrl_alt_bksp

Others have recommended that I add this line to my ~/.xinitrc however doing so has no effect once I restart gdm and log in (i.e. C+A+B doesn't work). Short of adding a shell script and making it run when I log into gnome, is there a better way to have that setxkbmap line run?

@karol - I tried that and as well. Also, I tried his other suggestion to add the line to my /usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi

Neither of which worked after I manually restarted gdm

In case this is my error, here is the keyboard line from my /etc/X11/xorg.conf as it appears in the file:

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
       Option  "XkbOptions" "terminate:ctrl_alt_bksp"

Here is my modified /usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->

Assume you did a hal restart after changing 10-keymap.fdi?

karol · 2009-05-31 10:37:50

You can either execute that command after you've logged in by some script magic or find out what files does gnome-session sources and try to add that line somewhere. I don't know if rc.local is a good place for such a hack.
