I have a new information: The command dexconf has nothing to do with the problem. If I boot from the LiveCD, enter the command "startx", close the GUI (=stop the x-server) and enter "startx" again, then the "AltGr" key works. But why does the "AltGr" key doesn't work when I start the x-server the first time? Please give me some help, it is very important for me. Thank you very much.
