SUMMARY In Plasma, when I add a second layout the layout that containts 'grave' as the secondary symbol in /usr/share/X11/xkb/symbols/ then while in the first layout pressing alt+(the key that contains grave in the second layout) no longer registers, so even when testing with 'xev' pressing the alt+key will not register a KeyPress event, only a KeyRelease event. Removing the secondary layout or removing the 'grave' from the symbols definition in the aforementioned directory will make the Alt+key work again. STEPS TO REPRODUCE 1. Add Arabic as Secondary Layout 2. While in primary English layout run Xev to test key presses 3. Press Alt+u in xev. OBSERVED RESULT The Keypress of Alt+u will not be registered. EXPECTED RESULT The Keypress of Alt+u should be registered.
