Yes, su is done by root, screen is run under the user account.

Well it appears the problem was that I had screen statements in ~/.screenrc

With:

   su - $u -c ". ~$u/.bashrc ; \
               screen -c ~$u/.screenrc-daemon -S $s -d -m vim'

and no screen statement in ~$USER/.screenrc-daemon
it works better.
