Tilde key on Mac Air with Ubuntu

rated 0 times [ 7] [ 0] / answers: 1 / hits: 16932 / 3 Years ago, thu, may 13, 2021, 6:40:14

By default, no layout on my Macbook Air allows me to print backtick (`) and tilde (~) symbols. Instead, I get backslash, pipe or whatever, depending from the layout.

I changed the behavior of the key that I want to use to print tilde using the following commands:

xev

<press tilde button>

keycode <keycode from xev output> = grave asciitilde >~/.Xmodmap

xmodmap ~/.xmodmaprc

(instructions are based on these https://stackoverflow.com/questions/17757232/switch-tab-and-backtick-keys-ubuntu-linux)

But unfortunately, after I switch the layout, I get the default behavior again.

How to make these changes permanent?

Okay, I solved the problem.

First off, xmodmaprc doesn't work in Ubuntu 14.04.
The solution is to edit xkb (X KeyBoard extension) config files.

Find the file /usr/share/X11/xkb/symbols/pc, backup it, then open and comment out the line:

key <LSGT> {    [ less, greater, bar, brokenbar ] };

And on the next line, add the following:

key <LSGT> { [ grave, asciitilde, grave, asciitilde ] };

If you need to change configuration for another locale, check the folder /usr/share/X11/xkb/symbols/ and find the file corresponding to the locale you want to change.

To apply the changes, you have to remove all xkb cache files:

rm -rf /var/lib/xkb/*
