Ok, so I admit it's all my fault ... but can you help?
It seemed that my session had locked up. In frustration I pretty much banged across the keys with the control key down
. It came back to life but ....
the lower case keys now have strange representations (what some might call extended ASCII / PC-8 type characters), so f is a small circle, g is the + on top of a - symbol.
I've tried things like stty sane, loadkeys -d, loadfont, bash -l all to no avail.
Any thoughts as to what I have done - and how to undo it?
