Well thank you, but it does not work, with either combination, gr-pc.kmap or gr.kmap.
Perhaps I should try with setxkbmap, but although i have all Xorg tczs installed the command is not recognized by the terminal server. The letters remain english in the terminal, in text editors including LibreOffice...
The only thing that has worked until now is what i told before, via .filetool.lst, as described in other threads and insofar it has produced only accented latin on the console.
Thank you.
