I have an Ubuntu 11.04 install for which I can't seem to get the correct (UK English) keyboard mapping set on. Running setxkmap produces an error:
"XKB extension not present on :10.0".
If go to System -> Keyboards -> Layouts and select the only layout installed "English Keymap" and press Show, I get a blank dialog.
[Update]: I forgot to add that I'm using xrdp and that this is almost certainly connected to xrdp using it's own keyboard mapping files. What I can't tell is how it can be changed.
Does anyone know how I can install and activate the correct keymap?
