I am using "Ubuntu Xorg" inside of Ubuntu 21.10, cause on normal Ubuntu it was not possible for me to set up xmodmap inside of gnome applications (e.g. Firefox, LibreOffice, Terminal). My aim with xmodmap is to reconfigure the keys "AltGr" + "y" and "AltGr" + "x". And I don't found some other applications inside of Linux to do that.
My wish now is to fix the settings on login. So I worked all the solutions from this post, but nothing helps. This solutions are working inside of the other Ubuntu configuration, but not inside of Ubunto Xorg. How can I set xmodmap on autostart inside of Ubuntu Xorg?
