39 xlock locks the X server till the user enters their password at the
40 keyboard. While xlock is running, all new server connections are
41 refused. The screen saver is disabled. The mouse cursor is turned
42 off. The screen is blanked and a changing pattern is put on the
43 screen. If a key or a mouse button is pressed then the user is
44 prompted for the password of the user who started xlock.
45 If the correct password is typed, then the screen is unlocked and the X
47 server is restored. When typing the password Control-U and Control-H
48 are active as kill and erase respectively. To return to the locked
49 screen, click in the small icon version of the changing pattern.
50 In the lower part of the password screen a text is displayed. This
52 message is taken from the first file of the following that exists:
53 $HOME/.xlocktext, $HOME/.plan, or $HOME/.signature.
54 On systems which support new BSD style authentication, the password may
56 be prefixed by an authentication style followed by a colon (i.e.
57 "style:password"). See the login.conf(5) for more information on
58 authentication styles.
59
62 Xlock should not be used on public terminals when there is a high
63 demand for them.
64 If you find a public terminal that has been locked by another user and
66 there are no other terminals available, and the terminal appears to
67 have been left idle for a while (normally more than 15 minutes), it is
68 fair to try to reset the session in some manner.

398 -delay usecs
401 The delay option sets the speed at which a mode will operate. It
402 simply sets the number of microseconds to delay between batches of
403 animations. In blank mode, it is important to set this to some
404 small number of seconds, because the keyboard and mouse are only
405 checked after each delay, so you cannot set the delay too high,
406 but a delay of zero would needlessly consume cpu checking for
407 mouse and keyboard input in a tight loop, since blank mode has no
408 work to do.

718 wator, and wire. In pipes it is the maximum length of a system.
719 In flow and swarm it is the length of the lines. In atlantis it
720 is the shark size. A negative number allows for randomness, simi‐
721 lar to count. In atunnels, fire, gears, sballs and sproingies it
722 is the size of the screen (default 400), this is because on many
723 slow systems it runs too slow when the picture covers the full
724 screen. Set to 0 for full screen on fast machines.
725 -ncolors num
727 The ncolors option sets the maximum number of colors to be used.
728 -saturation value
730 The saturation option sets saturation of the color ramp used to
731 value . 0 is grayscale and 1 is very rich color. 0.4 is a nice
732 pastel.
733 -erasemode modename
735 As of this writing there are over 12 erase modes supported (if its
736 not chosen its assumed random). The erase modes are random_lines,
737 random_squares, venetian, triple_wipe, quad_wipe, circle_wipe,
738 three_circle_wipe, squaretate, fizzle, spiral, slide_lines,
739 losira, no_fade. modename is now similar to the option modelist
740 where you can it can be something like "all-losira" to get all
741 erasemodes but losira. Use a "+" or a "," to add modes like "spi‐
742 ral+venetian".
743 -erasedelay usecs
745 The erasedelay option sets the number of microseconds for steps of
746 the erasemode (a setting of 0 and the erasemode is bypassed).
747 +/-nolock
749 The nolock option causes xlock to only draw the patterns and not
750 lock the display. A key press or a mouse click will terminate the
751 screen saver.
752 -/+inwindow
754 Runs xlock in a window, so that you can iconify, move, or resize
755 it and still use your screen for other stuff. When running in a
756 window, xlock no longer locks your screen, it just looks good.
757 -/+inroot
759 Runs xlock in your root window. Like the inwindow option it no
760 longer locks the screen, it just looks good.
761 -/+remote
763 The remote option tells xlock to not stop you from locking remote
764 X11 servers. This option should be used with care and is intended
765 mainly to lock X11 terminals which cannot run xlock locally. If
766 you lock someone else's workstation, they will have to know your
767 password to unlock it. Using +remote overrides any resource
768 derived values for remote and prevents xlock from being used to
769 lock other X11 servers. (Use `+' instead of `-' to override
770 resources for other options that can take the `+' modifier simi‐
771 larly.)
772 -/+mono
774 The mono option causes xlock to display monochrome, (black and
775 white) pixels rather than the default colored ones on color dis‐
776 plays.
777 -/+allowaccess
779 This option is required for servers which do not allow clients to
780 modify the host access control list. It is also useful if you
781 need to run x clients on a server which is locked for some rea‐
782 son... When allowaccess is true, the X11 server is left open for
783 clients to attach and thus lowers the inherent security of this
784 lock screen. A side effect of using this option is that if xlock
785 is killed -KILL, the access control list is not lost.
786 -vtlock modename

794 vated.
795 restore means VT switch locking + switching to xlock VT when acti‐
797 vated + switching back to previous VT when desactivated.
798 noswitch means VT switch locking only when xlock VT is active.
800 -/+allowroot
802 The allowroot option allows the root password to unlock the server
803 as well as the user who started xlock. May not be able to turn
804 this on and off depending on your system and how xlock was config‐
805 ured.
806 -/+debug

812 password window. The default is to show this description.
813 -/+echokeys
815 The echokeys option causes xlock to echo '?' characters (default)
816 for each key typed into the password prompt. Some consider this a
817 security risk, so the default is to not echo anything.
818 -echokey echokey
820 The text character to use for echo key in echokeys .
821 -/+enablesaver
823 By default xlock will disable the normal X server's screen saver
824 since it is in effect a replacement for it. Since it is possible
825 to set delay parameters long enough to cause phosphor burn on some
826 displays, this option will turn back on the default screen saver
827 which is very careful to keep most of the screen black.
828 -/+resetsaver
830 By default xlock will call XResetScreenSaver. This may be unde‐
831 sirable with DPMS monitors.
832 -/+grabmouse
834 The grabmouse option causes xlock to grab the mouse and keyboard,
835 this is the default. xlock can not lock the screen without this.

865 you to the password screen as the first character in the password.
866 The default is to ignore the first key pressed.
867 -/+verbose
869 Verbose mode, tells what options it is going to use.

928 dow (normally the entire screen). The entire screen format is
929 still used for entering the password. The purpose is to see the
930 screen even though it is locked. This should be used with caution
931 since many of the modes will fail if the windows are far from
932 square or are too small (size must be greater than 0x0). This
933 should also be used with -enablesaver to protect screen from phos‐
934 phor burn.
935 -icongeometry geom
937 The icongeometry option sets geom the size of the iconic screen
938 (normally 64x64) seen when entering the password. This should be
939 used with caution since many of the modes will fail if the windows
940 are far from square or are too small (size must be greater than
941 0x0). The greatest size is 256x256. There should be some limit
942 so users could see who has locked the screen. Position informa‐
943 tion of icon is ignored.
944 -glgeometry geom
946 The glgeometry option sets geom the size of the screen for gl
947 modes. Not normally available or needed.

1719 xlock can appear to hang if it is competing with a high-priority
1720 process for the CPU. For example, if xlock is started after a process
1721 with 'nice -20' (high priority), xlock will take considerable amount
1722 of time to respond.
1723
1726 If the machine is using a shadow password system, then xlock may not be
1727 set up to get the real password and so must be given one of its own.
1728 This can be either on the command line, via the -cpasswd option, or in
1729 the file $HOME/.xlockrc, with the first taking precedence. In both
1730 cases an encrypted password is expected (see makekey(8)). If neither
1731 is given, then xlock will prompt for a password and will use that, also
1732 storing an encrypted version of it in $HOME/.xlockrc for future use.
1733
1736 If you use ssh-agent(1) to avoid entering a passphrase every time you
1737 use one of your ssh(1) private keys, it's good security practice to
1738 have ssh-agent forget the keys before you leave your terminal unat‐
1739 tended. That way, an attacker who takes over your terminal won't be
1740 able to use your private ssh keys to log in to other systems. Once you
1741 return to your terminal, you can enter the passphrase and re-add the
1742 keys to ssh-agent. There are a couple of ways in which xlock can help
1743 to automate this process. Firstly, the startCmd option allows xlock to
1744 be configured to run 'ssh-add -D' every time you lock the screen, so
1745 that your keys are automatically deleted from ssh-agent. If the
1746 passphrase on your ssh keys is the same as your password, then xlock
1747 can also be made to re-add the keys to ssh-agent when you unlock the
1748 screen, via the pipepassCmd option. This requires a bit of scripting,
1749 as the command must read your password from standard input and then
1750 automate the interaction with ssh-add to re-add the keys. There is an
1751 example of such a script in the xlock distribution - see etc/xlockssh*
1752
1755 "kill -KILL xlock " causes the server that was locked to be unusable,
1756 since all hosts (including localhost) were removed from the access con‐
1757 trol list to lock out new X clients, and since xlock could not catch
1758 SIGKILL, it terminated before restoring the access control list. This
1759 will leave the X server in a state where "you can no longer connect to
1760 that server, and this operation cannot be reversed unless you reset the
1761 server." -From the X11R4 Xlib Documentation, Chapter 7.
1762 NCD terminals do not allow xlock to remove all the hosts from the
1763 access control list. Therefore you will need to use the "-remote" and
1764 "-allowaccess" switches. If you happen to run without "-allowaccess"
1765 on an NCD terminal, xlock will not work and you will need to reboot the
1766 terminal, or simply go into the SETUP menus, under 'Network Parame‐
1767 ters', and turn off TCP/IP access control.
