I've just installed Ubuntu Server 11.10 and the tilde (~) and double quotes (") keys don't do anything - they don't print to the screen. I'm only using the command line (no GUI) and many tutorials say to use setxkbmap and xmodmap which aren't working for me.
For those not using XWindows, e.g. Ubuntu server,
setxkbmap won't work.
sudo apt-get install console-common
Or if it is already installed:
sudo dpkg-reconfigure console-data
Follow the instructions to set the keyboard, e.g. for me, "pc / qwerty / US american / Standard / Standard".
You can change the keyboard in the Ubuntu System Settings, Text Entry. Remove the English(UK) from 'Input sources to use:' by selecting it in the list and clicking '-'. (Tested in ubuntu 14.04)
I also had the same issue..but fixed it using methods below -
Permanent Solution: In a Linux dist. OS use the following keyboard layout - "English(US,with euro on 5)"
Temporary Solution: use the following key combination - 'Alt' + 'Shift' + " "
or 'Alt' + ' '
Hopefully. this will solve your problem.. :)
Be careful with a command
$ setxkbmap -layout us because for instance in my case, my another keyboard input source (ukrainian) also switched into english, so I did not have kyrillic letters anymore.
So, my suggestion will be simply changing manually 'English (US, alt. intl.)' into 'English (US)'.
