Resetting and *locking* the Desktop in Ubuntu 14.04

[Robert Heller]

We have a batch of public workstations and sometimes, somehow (I don't know 
how -- I am not a user of pointy-clicky desktop file managers), the desktop 
file manager displays ~home/ instead of ~home/Desktop.  How do I fix this and 
how do I prevent users from randomly changing it?  Specificly, what config 
files are being messed with and how do I "lock" those files (eg make them 
non-writable or something).  And no, I don't want a pointy-clicky solution, I 
want a solution I can implement from the command line, since I suspect it 
might be a matter of running a daily cron job to fix/re-fix.
