I'm using Belgian keyboard settings on Ubuntu 13.04 (Belgisch). When I want to type a third level key such as # or @ it only works with AltGr. I want it to work with both Ctrl+Alt (left) and AltGr (right). For some reason I can't find a way to do this. My left Alt key is set to MetaL and the AltGr key is set to Lvl 3 s... How can I fix this that left Alt key is just Alt L and AltGr key is just AltGr the way it was on Windows? I don't need the Meta L key!
