[Solved] keycode 58 = Escape has 0 effect

doums · 2019-03-15 03:30:53

Hi,

I'm trying to map the CapsLock key to Escape only for console.
So I followed the doc without any changes and any success
What I did:

/usr/local/share/kbd/keymaps/personal.map

include "/usr/share/kbd/keymaps/i386/azerty/fr-pc.map.gz"

keycode 58 = Escape

/etc/vconsole.conf

KEYMAP="/usr/local/share/kbd/keymaps/personal.map"

I have checked the key code of CapsLock which is 58, with the following:

# showkey -k
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  28 release
keycode  58 press
keycode  58 release
keycode  58 press
keycode  58 release

And finally I reloaded successfully the config with loadkeys /usr/local/share/kbd/keymaps/personal.map and even with restarting the laptop -> 0 change at all

I also tried directly under X with xmodmap and ~/.Xmodmap:

clear lock
keycode 66 = Escape

And it works perfectly but the CapsLock key is mapped to Escape in the whole X and that's not what I want.

Why it does not work for virtual console ?
Note: I also tried by replacing 58 by 66 but no success too

Since it looks a lot like you're on an X11 session, please clarify what you're trying to do:
alter the escape key on a VTE in X11 (xterm, urxvt, terminator, konsole, gnome-terminal, …) or on the linux console (multi-user.target, no GUI stuff whatsoever)?

Also this sounds like an xy-problem. What itch do you ultimately want to scratch?

I want to replace the capslock key by escape to use with any terminal emulator like terminator and xfce4-terminal (I use the first one).
I'm on Xfce4 4.12, terminator 1.91

I remapped my <capslock> key to the <home> (as I don't have a dedicated home key) in X11 by first installing xxkb, then editing /usr/share/X11/xkb/symbols/us <- because I am using the us keyboard

here is the updated file

    key <BKSL> {    [ backslash,         bar    ]   };
};

I'm sure there is a more intelligent way but for me it works at the moment

*Note: I found the key codes in /usr/share/X11/xkb/keycodes/evdev

Ok so the problem was I thought that setting /etc/vconsole.conf to an extended keymap will set stuff for terminal emulator but it's wrong because (if I understand well), using /etc/vconsole.conf only sets the mapping for linux console, not terminal emulation (which run in X session).

So alter the X mapping is the good way to go, for example using ~/.Xmodmap like described in the main post.

Thank you all.

vconsole.conf only sets the mapping for linux console

Yup.

There's actually an xkb option "caps:swapescape" or "caps:escape" which you could use rather than xmodmap (adding that option to your xorg conf will maintain the behavior when the keyboard gets re-added, eg. after an S3)

Limiting the effect to a VTE is gonna be tricky ("impossible") because caps lock acts as a toggle for the shift modifier (ie. this is not a "real" key)

For "normal" keys at least xterm allows to override their behavior, eg.

xterm.vt100.translations: #override <Key>KP_Delete:string(.)

can be handy for numpad centric xterms outside US locales.

Ok thanks for these tips!

I replaced .Xmodmap file by /etc/X11/xorg.conf.d/01-keyboard.conf (which extends my base keyboard config 00-keyboard.conf) with

Section "InputClass"
    Identifier "capslock to escape"
    MatchIsKeyboard "on"
    Option "XKbOptions" "caps:escape"
EndSection

And it works perfectly
