     Pressing Ctrl with any mouse button displays menus for me without any
     error.  Did you install any font in your profile?  Try for example,
     "guix package -i font-dejavu".  Perhaps you will also need to run
     "fc-cache -f".

So that means that font-dejavu should be an input of xterm.  Shall I make that
change?


     To make Xterm use a font I want, I have these lines in my ~/XTerm (it
     can also be placed in ~/.Xresources I think):
     
     XTerm*faceName: DejaVu Sans Mono
     XTerm*faceSize: 12
     

Presumably there is a default font which should work without any resource explicitly set?
