Some shortcuts like "Alt" + "Tab" or "Cntl" + "Alt" + arrowkey are not recognized as shortcut. Reproducible: Always Steps to Reproduce: 1. Install kubuntu 15.04 with German/Neo2 as keyboard layout 2. Try to change Task with "Alt" + "Tab" 3. Set Switch One Desktop Down/Up/Right/Left to "Cntl" + "Alt" + arrowkey 4. Try to change the Desktop Actual Results: Both Keys are recognized, but as individual keypresses and not as combination. Expected Results: The Task or desktop should be switched Other shortcuts like "Cntl"+"Alt"+"l" (logout) or "Shift"+"Tab" (Switch Tab) are working and are logged into journalctl. If I try the same with "normal" german keyboard layout, all shortcuts work as expected. If I change Change Task to "Cntl"+"Alt"+"l" this shortcut is also working.
