X and keymaps/codes

I've run into real problems.. I should run Reflection X server on my Windows box to connect to Linux, but I can't get the keys to work correctly. When I look in xev things look right, at least some of them. I have Swedish keymap and of course a Swedish keyboard. So my @£${[]} and \ are mapped to <alt-gr> buttons. However, none of them works in Reflection, when running xev I see that when I press <alt-gr> I get the mapping to "Mode_switch" which is correct. But it doesn't modify the keys, so nothing shows up when I f.x. type <alt-gr>-4 to get a $. Any ideas on how I can troubleshoot this? Anders.
