Why does my compose key not work after a reinstall?












0














mapped Alt Gr to Compose. If I use Alt Gr in combination with another key, then it behaves like a modifier, like Shift or Ctrl, but if I press it and release it, then it behaves like a Compose key. I could press Alt Gr, then a, then e, to get æ for example.



At least, that's how it used to work. Now, I have re-installed Linux Mint, and though the configuration didn't change, the behaviour did. xev still reveals that Alt Gr is keycode 108.



This line



xmodmap -e "keycode 108 = Multi_key"


still gets executed when I log in. But the key does nothing! What has happened?



Thinking this was a subtle change to do how a keysym can be mapped to a modifier key, I tried



xmodmap -n -e "keycode 94 = Multi_key"


which is the backslash key to the left of Z. Alas, that doesn't do anything either.



Have I even got the right xmodmap installed?



$ sudo apt-get install xmodmap
[sudo] password for you:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package xmodmap is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
x11-xserver-utils:i386 x11-xserver-utils

E: Package 'xmodmap' has no installation candidate
