I can't type those german/swedish öäü-letters anywhere(Had to copy/paste those from a website). I think utf-8 works, cause i can write the norwegian ØÆÅ. The german/swedish characters doesn't work in urxvt and not in firefox. I have a Norwegian keyboard. In Windows I can do it. Could there be any things interesting in xorg.conf or something? Isn't it possible to have them both work?

usually I need to click first on one button to create the ¨-symbol and then on either "o", "u", "a" etc..but now the ¨-symbol appears as soon as i click on it. It doesn't wait for a follow-up-keypress.

Thanks for reading!

Solved! turning off "nodeadkeys" in xorg.conf solved it!
