     Runs xxxxlllloooocccckkkk in a window, so that you can iconify,  move,

----////++++rrrreeeemmmmooootttteeee
     The _r_e_m_o_t_e option tells xxxxlllloooocccckkkk  to  not  stop  you  from
     locking remote X11 servers.  This option should be used
     with care and is intended mainly to lock X11  terminals
     which  cannot  run  xxxxlllloooocccckkkk locally.  If you lock someone
     else's workstation, they will have to know  yyyyoooouuuurrrr  pass-
     word   to  unlock  it.   Using  +_r_e_m_o_t_e  overrides  any
     resource derived values for _r_e_m_o_t_e and  prevents  xxxxlllloooocccckkkk
     from  being  used  to lock other X11 servers.  (Use `+'
     instead of `-' to override resources for other  options
     that can take the `+' modifier similarly.)

----////++++mmmmoooonnnnoooo
     The _m_o_n_o option causes  xxxxlllloooocccckkkk  to  display  monochrome,
     (black  and  white)  pixels  rather  than  the  default
     colored ones on color displays.

----////++++aaaalllllllloooowwwwaaaacccccccceeeessssssss
     This option is required for servers which do not  allow
     clients  to modify the host access control list.  It is
     also useful if you need to run x clients  on  a  server
     which is locked for some reason...  When _a_l_l_o_w_a_c_c_e_s_s is
     true, the X11 server is left open for clients to attach
     and  thus  lowers  the  inherent  security of this lock
     screen.  A side effect of using this option is that  if
     xxxxlllloooocccckkkk  is  killed -KILL, the access control list is not
     lost.

-vvvvttttlllloooocccckkkk _m_o_d_e_n_a_m_e

_o_f_f       means no VT switch locking.

_s_w_i_t_c_h    means VT switch locking + switching  to  xlock  VT

     enough  to  cause  phosphor burn on some displays, this

     is very careful to keep most of the screen black.

     Not implemented for all mode options.

-mmmmooooddddeeeelllliiiisssstttt _t_e_x_t_s_t_r_i_n_g
     Allows one to pass a list of files to randomly  display
     to _r_a_n_d_o_m. "all" will get all files but blank (and bomb
     if  compiled  in).  "all,blank"  will  get  all  modes.
     "all,-image bounce,+blank" will get all modes but image
     and bounce.  "bug wator" will get only bug  and  wator.
     "allgl"  will  get  only  the  GL modes if compiled in,
     all-allgl will get all but the GL modes, "allnice" will
     weed  out  high cpu usage modes (as well as hackers and
     gl modes).  "allxpm" will get all modes that  use  xpm.
     "allwrite"  will  get  all modes that take advantage of
     writable colormaps (not including xpm).   "all3d"  will
     get all the modes that support this option.  "allmouse"
     will get all the modes that support mouse  interaction.
     Similarly,  "allautomata" for automata modes, "allfrac-
     tal" for  fractal  modes,  "allgeometry"  for  geometry
     modes,  "allspace"  for  space  modes.  The random mode
     itself can not be referenced.

     Turn on non-random _r_a_n_d_o_m option.


********WWWWAAAARRRRNNNNIIIINNNNGGGG********
xxxxlllloooocccckkkk can appear to hang if it is  competing  with  a  high-
priority  process  for  the  CPU.  For  example, if xxxxlllloooocccckkkk is
started after a process with  'nice  -20'  (high  priority),
xxxxlllloooocccckkkk will take  considerable amount of time to respond.

2 If the machine is using a shadow password system, then xxxxlllloooocccckkkk
may  not  be  set up to get the real password and so must be
given one of its own. This can  be  either  on  the  command
line,   via   the   ----ccccppppaaaasssssssswwwwdddd   option,   or   in   the  file
$$$$HHHHOOOOMMMMEEEE////....xxxxlllloooocccckkkkrrrrcccc, with the first taking precedence.   In  both
cases  an  encrypted  password is expected (see makekey(8)).
2 If neither is given, then xxxxlllloooocccckkkk will prompt for  a  password
and  will  use that, also storing an encrypted version of it
in $$$$HHHHOOOOMMMMEEEE////....xxxxlllloooocccckkkkrrrrcccc for future use.

"kill -KILL xxxxlllloooocccckkkk " causes the server that was locked to  be
unusable, since all hosts (including localhost) were removed
from the access control list to lock out new X clients,  and
since  xxxxlllloooocccckkkk  could  not catch SIGKILL, it terminated before
restoring the access control list.  This will  leave  the  X
server  in  a state where "_y_o_u _c_a_n _n_o _l_o_n_g_e_r _c_o_n_n_e_c_t _t_o _t_h_a_t

tation, Chapter 7.
2 NCD terminals do not allow xlock to  remove  all  the  hosts
from  the  access  control list.  Therefore you will need to
use the "-remote" and "-allowaccess" switches.  If you  hap-
pen  to run without "-allowaccess" on an NCD terminal, xxxxlllloooocccckkkk
will not work and you will need to reboot the  terminal,  or
simply  go into the SETUP menus, under 'Network Parameters',
and turn off TCP/IP access control.
