You can turn off locking the screen and not even use a screensaver. Those
are just frills and not really just a part of Linux. Passwords are not
unique to Linux, but they are integral to the OS and trying to circumvent
them is not a good idea especially for newbies. Linux veterans are not put
off by them. So what kind of user are we talking about?
As always I try to look at the big picture and think of others reading and
try to reinforce Linux ways. :-)
We are probably in agreement on the big picture. Sure turn off screen locks
and remove passwords from screensavers. They are just annoyances anyway, but
it is not wise to bypass built in security. Users do so at their peril.
