Hei! :-)

So, in Ubuntu you use the no(colemak) layout? Not for instance my Big Bag one?

In that case, you're using what I call the "Keep Local Symbols" layout. There aren't "QWERTY" positions for your symbols as such but I guess you mean the Norwegian QWERTY positions; if that's what you want then "Keep Local Symbols" is your thing.

Indeed, you shouldn't settle for the standard Colemak AltGr mappings! But please read my Big Bag Locale topic to see how I made the Norwegian Colemak as a "Unified Symbols" variant; I really think it's far superior. You'll find a Norwegian Colemak in my PKL files since I'm Norwegian myself; my own default may use the DH-mod now though but you can change the layout file to the layout without that. However, my file also uses the US symbol positions and not the Norwegian QWERTY ones! One way around that is setting all symbol keys to 'virtualkey' (see the vk_ layouts for examples) so the system mappings are used, but then you'll miss out on all the exciting dead keys and stuff. Another way is remapping the whole thing as you want it. I'd still recommend taking another long hard look at my mappings first – they're really quite good! ;-)
