I only could take screenshots from the GUI programs to set the keyboard settings and to set the country settings. I am still looking for some command or what system file to list to unambiguously communicate those system settings. I searched long and still did not find a way how to unambiguously communicate what language settings are in effect on my computer. Problems risen during trials to narrow down the issue They could not reproduce this problem with Ubuntu 18.04 and they asked me for the exact settings of my keyboard and language settings. Unfortunately the caret character ^, akut ´ and gravis ` are used frequently within that program.

neither does pressing them twice produce those accents alone nor does pressing them once followed by one of the characters known with that accent after it produce the accent carrying version of that character.

I installed a new version of a commercial program which differs from all other Ubuntu programs which I used so far (including the previous version of that program) with respect to keyboard entry: It suppresses the dead keys, i.e. I am running a Lenovo laptop W530 and the keyboard is a German one (QWERTZU). This question pertains to an installation of Xubuntu 16.04.3 LTS with current kernel 4.4.0-116-generic x86_64.
