I want to add greek polytonic keyboard layout under Lubuntu (so in LXDE). I already realized there is no easy tool to do it with the graphic interface, so I need to use setxkbmap executing something the like of:
setxkbmap pl,gr
Now, how to make setxkbmap set the greek polytonic variant?
To set it with setxkbmap:
setxkbmap 'pl,gr' -variant ',polytonic' -option 'grp:alt_shift_toggle'
-variant sets variants for each selected layout and -option 'grp:alt_shift_toggle' enables switching layouts with Alt-Shift.
The available layouts and variants can be seen in /usr/share/X11/xkb/symbols. Every layout has its file and by listing such file you can find the variants of the layout.
(BTW the options are listed in /usr/share/X11/xkb/symbols.)
If you need to make the settings permanent, instead of using setxkbmap, you can edit /etc/default/keyboard.
