I have a problem with keyboard layouts in my Xubuntu. It's described in my previous question. I tried many settings and special commands and it seemed to work (that is why I selected my previous question as solved), but then I realized every now and then (no idea when exactly and why) it switches to Czech QWERTZ again. After a while, it's back to Czech QWERTY. That's insane and totally against logic. My setting is EN US / CZ QWERTY everywhere.
I realized there is probably no peaceful solution. So I ask: Is there a way to completely remove Czech QWERTZ keyboard layout from my computer? Send it to a black hole at the opposite side of universe or something similar?
