∶ 我也有同样问题，只是root用户屏保无效，LOCK SCREEN也不行；
∶ 而新创建的一般用户则屏保可以，LOCK SCREEN也行

去看看man page. 没事用什么root来锁屏?

       Locking and root logins
               In order for it to be safe for xscreensaver to  be
               launched  by  xdm,  certain  precautions had to be
               taken, among them that xscreensaver never runs  as
               root.   In  particular,  if it is launched as root
               (as xdm is likely to do), xscreensaver  will  dis-
               avow  its  privileges, and switch itself to a safe
               user id (such as nobody.)

               An implication of this is that if you  log  in  as
               root  on  the console, xscreensaver will refuse to
               lock the screen (because it can't tell the differ-
               ence  between root being logged in on the console,
               and a normal user being logged in on  the  console
               but  xscreensaver  having  been  launched  by  the
               xdm(1) Xsetup file.)

               The solution to this is simple: you  shouldn't  be
               logging  in  on  the  console as root in the first
               place!  (What, are you crazy or something?)
               Proper Unix hygiene dictates that you  should  log
               in  as  yourself,  and su(1) to root as necessary.
               People who spend their day logged in as  root  are
               just begging for disaster.
