I've tried setting org.gnome.desktop.input-sources to ['space:ctrl'] but it doesn't work.

Note: I want the spacebar to keep working as before (Space should trigger both Ctrl and Space, I don't mind the conflict).

  • Please show us the exact command you used. – Gunnar Hjalmarsson Aug 08 '16 at 17:19
  • Did it via dconf-editor, these are the exact values I used. – seriousdev Aug 08 '16 at 17:33
  • What's the output of gsettings get org.gnome.desktop.input-sources xkb-options? – Gunnar Hjalmarsson Aug 08 '16 at 18:09
  • I tested, and it didn't work for me either. Probably it's not a valid xkb-options value. You can run localectl list-x11-keymap-options to view a list of valid values. – Gunnar Hjalmarsson Aug 08 '16 at 18:54
  • You wanted Space should trigger both Ctrl and Space, but what it should do for shortcuts which needs combination of Ctrl and Space? Not at least with preserving the original behaviour. What I understand from the question is, you wanted the space to act like Ctrl when you want it and like Space, when you don't. That's not possible now – Anwar Aug 17 '16 at 06:40
  • @Anwar You misunderstood: I don't mind the conflict since I never use Ctrl and Space together. – seriousdev Aug 17 '16 at 15:34
  • This is a very good good question. Me just looking up different ideas https://github.com/r0adrunner/Space2Ctrl https://github.com/alols/xcape – William Jul 07 '20 at 12:43

From a terminal run:

xmodmap -e 'keycode 65=Control_R'

To undo, type:

xmodmap -e 'keycode 65=space'

In general, to see the list of all keysyms that you can map and their names, type:

xmodmap -pk
  • Not working for me on Ubuntu 16.04. Tried mapping both Control_R and Control_L but the usual shortcuts aren't working in any application. Also I'd like for the spacebar to still work as before, I'll update my question to reflect this. – seriousdev Aug 15 '16 at 16:27
  • Mmm, does this or this answer help? –  Aug 15 '16 at 18:54
