Hello, sometimes I press this combo by accident. The reason is simple, I often switch between english and hungarian language (alt-ctrl-k), and then I delete the latest character which is bad (because I didn't write it with the corresponding layout). Sometimes the layout doesn't change (don't know why. Maybe it's my mistake, however I play to much with FPS games to be unable to press three keys same time). So I have to press backspace multiple times and then my X server restarts. Then I would like to get an axe and break everything in my room. I tried to disable this combination however I didn't find it in the KDE setup between the other combos. Well, maybe it's X. Can you help me? Mage ___________________________________________________ .
