Any ideas and/or suggestions?
I wouldn't have said that was a hole "per se", more a "feature" with
the way that `su -l` is designed to work. The point of the -l switch
is that the environment is set from a clean slate when entering the
new user context. This means that any pre-existing DISPLAY variable
will be blanked out along with the rest of the new shell's
environment. Then /etc/profile is run through to set up the initial
environment for said new shell, which will detect the lack of DISPLAY
variable and set up the default (192.168.11.1:0.0).
