Mär 23:47 /dev/tty2 Adding your user to group tty probably wouldn't resolve your problem (not tested), because group doesn't have any rights. So it seems that after login you first have to chmod 770 the tty before you do a su - user (user have to be in group tty of course). Maybe it would ease things when you write a little script for this procedure. -- Regards wabe
