I 'downgraded' to the ...1vl60 version, it installed properly and I rebooted, ran KDM update to select the autologin option again and ... it works!!! The computer automatically logs in the right user, sets up the wireless very rapidly indeed and then is good to go. Brilliant.
Incidentally, I got Gslapt to update the available packages list after 'downgrading' the version of kdm-small - and the ...2vl60 version no longer appears as an option.
Well, I've learned quite a bit thanks to your help. I'm not sure exactly what
I've learned yet, but i know it is quite a lot.
Now I just need to set it up on my friend's network.
I'll let you know how I get on.
Many thanks indeed. Would never have got this far without your expert help.
