I don't even have an AltGr button on my keyboard (!). It would be very cumbersome to write swedish with AltGr though, as the characters are quite common.
Not even a right Alt key - should be the same if you set the layout..? That's a really minimal keyboard, all 60% keyboards I've seen and even some 40% keyboards have that... I'd actually be curious to see your bastard keyboard!
YMMV, but I got used to it pretty quickly and I type Swedish all the time, way less annoying than doing the Alt-shift dance to switch layouts whenever I go from coding to chatting at least ;)
I always have an AltGr key, because I tend to program on Finnish keyboards. (Identical layout as Swedish, but because nobody came up with a term to group those 2 together, there seem to be always 2 options to chose that make no difference...) What I really hate about AltGr / this layout is the curly braces and square brackets. It makes programming so much harder to need to use AltGr for each of them.
That said in Linux/X11 you could configure everthing to your likings. I must admit I prefer complaining...
Yeah, this is exactly the reason I stopped using the Swedish/Finnish layout altogether. It must be hundreds or even thousands of time I accidentally typed :( instead of :) in IMs because someone at some point decided the parentheses had to be shifted one step...
Right-alting for åäö is just way less cumbersome than doing the same for @${}[]\~| or having to switch layouts when switching contexts.
