Hi gerald,
Belive me, you and the other advanced users did help mi decisively! In this forum there are great people. So, let me inform you.
The only way to install a working german layout was by putting in the 10-keyboard.conf file, like to say the keyboard section Xorg.conf. All that makes sense, but I needed an evidence to get sure about what happens. So I reinstalled the OS from scratch, but this time with a bit more knowledge and experience.
- I have a lot of trouble with the initial tiny core configuration which starts approx. every tenth time. In order to get a stable OS I need to use xorg instead the "native" vesa.
- In such circumstances I needed some patience by experimenting but I acknowledged that under xvesa "loadkmap < /usr/share/kmap/qwertz/de-latin1-nodeadkeys.kmap" works even as kernel parameter, of course in the form "kmap=qwertz/de-latin1-nodeadkeys". No need of installing packages, for example kmap or however sounds the proper name.
- After installig xorg the x server recognizes only xorg instructions exactly like most people who doesn't speak foreign lenguages.
- I didn't find out how to put in a persistent file, however I didn't yet study with attention the remastering panel. On the moment I am planning just "cp 10-keyboard.conf /usr/local/share/X11/xorg.conf.d" and let see.
OK Jerry, what I didn't put down is my laptop model:
MSI 60 2PC Apache, 8 Gb RAM, Nvidia GTX850M,
Optimus technology, installed succesfully under SuSE and Mint
Once more thanks for the great help. On the end, I am planning a recapitulation post for your attention and corrections.
