What I don't know is what is causing the problem. The rest of the keyboard layout continues to work, only Alt Gr is gone. So far only loging out and in cures the problem.
This is strange as I never had a problem with the keyboard. I have DE,US,BG,RU at home and DE,CH,US,BG in the office.
I use jessie with TDE 14.0.2
What debian version do you have and what TDE?
Perhaps you should check the settings - example disable external xkb or alike.
German - nodeadkeys ... for CH I don't know which variant is setup ATM.
If its not a setting, it could software defect for the keyboard model (did you try with another one) or even a hardware defect.
