I just looked up /usr/share/X11/locale/en_US.UTF-8/Compose
and there is no dead_greek
character. There are only dead_acute
, dead_iota
, and the like to combine with alpha.
There is no plain greek alpha in this file.
If you use gnome, look at this answer How can I map a character to a key combination? over at http://askubuntu.com. In your case this would be
Ctrl-Shift-u03b1space
If you have no dead_greek key in your xmodmap output, you can add one yourself. Search for a key you want to use for that purpose, right windows key or right super key for example. Then you can replace the definition of this key with dead_greek
keycode 133 = dead_greek NoSymbol SuperR
xmodmap -pke
might give you some hints about nearby keys... – Blasxmodmap -pke |grep -i greek
