How to change decimal comma to decimal period in numpad?
Solution 1
I think the problem is that you are mixing xmodmap
commands with setxkbmap
commands (whether on the command-line or by using the graphical settings menus). As you have observed, the setxkbmap
commands will override the xmodmap
commands when you change your keyboard layout. The logical solution would therefore be to use setxkbmap
to change both your layout and the keypad comma to a decimal period.
When you use setxkbmap
to change your layout any specified customisations will also be applied: the full list of options is available at /usr/share/X11/xkb/rules/evdev.lst
. I don't know which language layouts you use, so I have placed just two examples at the end of the following command, which you can use to switch layouts with ALt+Shift. If you have any more key mappings or bindings you want to activate, simply add them to the command:
setxkbmap -option '' -option kpdl:dot -option grp:switch,grp:alt_shift_toggle gb,nl
The first command switch (-option ''
) clears any current settings, as when new settings are given they are added to and do not replace any existing ones unless this option is used. The second (-option kpdl:dot
) makes sure that the appropriate keypad key is a dot or period; the third command switch (-option grp:switch,grp:alt_shift_toggle
) sets up your ability to switch the layouts with ALt+Shift, and the last (gb,nl
) specifies the layouts to switch to.
To check your settings, you can enter
setxkbmap -query
which results in:
rules: evdev
model: pc105
layout: gb,nl
options: kpdl:dot,grp:switch,grp:alt_shift_toggle
Add the full setxkbmap
line further above as a startup item to make sure it is activated and available for you to use.
More information on setxkbmap
is available by entering man setxkbmap
or by viewing the Ubuntu manpages online.
Solution 2
In Ubuntu 14.04 LTS, there are at least two ways to do this. Assumptions:
- You want to do this for Unity (graphical environment).
- The goal is just to change comma to dot, not to change the whole layout or other options.
Option 1: GUI (dconf-editor)
Run (Alt+F2) "dconf-editor", navigate in the tree to schema "org.gnome.desktop.input-sources" and set the key "xkb-options" to value that you want, e.g. "['kpdl:comma']" or "['kpdl:dot']".
Values are defined in xkeyboard-config help:
man xkeyboard-config
This is what I found there:
Numeric keypad delete key behaviour
┌─────────────────────────────────────────────────────────────────┐
│Option Description │
├─────────────────────────────────────────────────────────────────┤
│kpdl:dot Legacy key with dot │
│kpdl:comma Legacy key with comma │
│kpdl:dotoss Four-level key with dot │
│kpdl:dotoss_latin9 Four-level key with dot, Latin-9 only │
│kpdl:commaoss Four-level key with comma │
│kpdl:momayyezoss Four-level key with momayyez │
│kpdl:kposs Four-level key with abstract separators │
│kpdl:semi Semicolon on third level │
└─────────────────────────────────────────────────────────────────┘
Option 2: Command line (gsettings)
You can also use command line instead of dconf-editor GUI to accomplish the same. Like this:
gsettings set org.gnome.desktop.input-sources xkb-options "['kpdl:comma']"

How to change the decimal comma ',' to decimal period '.' in the numeric pad of the keyboard?
I have used
xmodmap
but every time that I change my keyboard layout the changes (by xmodmap) are being reset.-
NickTux over 11 yearsHave you seen this answer ? How do I remap certain keys?
-
Huckle over 11 yearsI imagine that this would be part of the keyboard layout, no? If it is a US-style keyboard you may be able to switch to a European-style where that key would likely be a comma. You'll have to suffer the consequences of having a Pound (curreny) sign instead of a pound (hash) on the Shift-3 however.

Admin over 11 yearsHow are you saving the settings? Putting them in
~/.Xmodmap
and then puttingxmodmap ~/.Xmodmap
in~/.xinitrc
usually works. Alternatively, you could add the commandxmodmap ~/.Xmodmap
as a startup item. -
pl1nk over 11 years@Mik - The
Xmodmap
are being called by a startup script, which is working until changing keyboard layout where Xmodmap settings are being reset.

kanu about 10 yearsI have the same problem again. However in Ubuntu 14.04 I switch layouts with
Super
+Space
. What kind of command must I use in this case? -
HelloGoodbye over 6 yearsI don't have any program called "dconf-editor".
-
okolnost over 6 yearsI am not sure if it is installed by default. It depends on what distribution you have. It should be part of Gnome-based Ubuntu distributions (i.e. not Kubuntu for example). wiki.gnome.org/action/show/Projects/dconf
-
okolnost over 6 yearsIf you want to install it, simply run "sudo apt-get install dconf-editor".

sdlins about 6 yearsIt should be the accepted answer. Worked for me in Ubuntu 18.04 beta (after
sudo apt install dconf-editor
). Thank you!
