🌸 DESCRIPTION 🌸

Okay so picture this: xlock locks the X server till the user enters their password at the keyboard. While xlock is running, all new server connections are refused. The screen saver is disabled. The mouse cursor is turned off. The screen is blanked and a changing pattern is put on the screen. If a key or a mouse button is pressed, then the user is prompted for the password of the user who started xlock.

If the correct password is typed, then the screen is unlocked and the X server is restored. When typing the password, Ctrl+U (Control-U) and Ctrl+H (Control-H) are active as kill and erase respectively. To return to the locked screen, click in the small icon version of the changing pattern. Cute, right? 🎀

In the lower part of the password screen a text is displayed. This message is taken from the first file of the following that exists: $HOME/.xlocktext, $HOME/.plan, or $HOME/.signature. Yes, it checks them in that order. 💅

On systems which support new BSD style authentication, the password may be prefixed by an authentication style followed by a colon (i.e. "style:password"). See the login.conf(5) for more information on authentication styles.

🎀 NOTE ON ETIQUETTE 🎀

Xlock should not be used on public terminals when there is a high demand for them. Like, read the room, bestie. 🙈

If you find a public terminal that has been locked by another user and there are no other terminals available, and the terminal appears to have been left idle for a while (normally more than 15 minutes), it is fair to try to reset the session in some manner.

💅 OPTIONS 💅

-help — Print options and a brief description to standard output.
-version — Print version number (if >= 4.00) to standard output.
-resources — Print default resource file to standard output.
-display displayname — The display option sets the X11 display to lock. xlock locks all available screens on a given server, and restricts you to locking only a local server such as unix:0, localhost:0, or :0 unless you set the -remote option.
-visual visualname — visualname which is one of "StaticGray", "GrayScale", "StaticColor", "PseudoColor", "TrueColor", "DirectColor", or "default". default is used to set the screen's default visual (the visual of the root window).
-name resourcename — resourcename is used instead of XLock when looking for resources to configure xlock.
-mode modename — As of this writing there are over 90 display modes supported (plus one more for random selection of one of these).

random — Shows a random mode from above except blank (and bomb).

-delay usecs — The delay option sets the speed at which a mode will operate. It simply sets the number of microseconds to delay between batches of animations.

In blank mode, it is important to set this to some small number of seconds, because the keyboard and mouse are only checked after each delay, so you cannot set the delay too high, but a delay of zero would needlessly consume cpu checking for mouse and keyboard input in a tight loop, since blank mode has no work to do.

And yes, bestie: a negative count allows for randomness. The range goes from the minimum allowed nonnegative count for a particular mode to the ABS( count ) (or maximum allowed count, whichever is less). 💅

-batchcount num — The batchcount option is deprecated but should still work as count. 🫶
-cycles num — okay so this one is like the ✨main character✨ of "it depends on the mode" options 💅. It sets the number of cycles until time out for ant, ant3d, apollonian, blot, braid, bug, clock, crystal, daisy, deco, demon, dilemma, discrete, dragon, eyes, fiberlamp, flag, flow, forest, galaxy, helix, hop, hyper, ico, juggle, juggler3d, laser, life, life1d, life3d, lisa, lissie, loop, mandelbrot, mountain, petal, sierpinski, shape, spline +erase, t3d, thornbird, triangle, tube, voters, wator, and wire. And then it gets so specific, buckle up buttercup 🎀:
- for atlantis it is the shark speed 🦈
- for bevel it is the number of steps to complete a 180 degree move
- for dino it is the number of steps to complete a move of 120 or 180 degrees
- for euler2d and worm it is the length of the lines
- for fadeplot, julia and spiral it is the length of the trail of dots
- for munch it is the minimum size of the squares
- for kaleid it is the % of black
- for qix it is the number of lines
- for spline -erase it means the number of splines * 64 (for compatibility with +erase)
- for gears it is the number of degrees to increment the spin of each gear by
- for glplanet it is the number of hundredth degrees to rotate the planet by
- for mball it is the number of steps to complete a turn
- for molecule it is the time in seconds until timeout
- for oct it is the number of steps to complete a move of 90 or 120 degrees
- for pipes it is the number of systems to draw before clearing the screen
- for pyraminx it is the number of steps to complete a move of 120 or 180 degrees
- for rubik it is the number of steps to complete a 90 degree move
- for sballs it is the sphere speed value
- for scooter it is the speed
- for skewb it is the number of steps to complete a 120 degree move
- for superquadrics it is the number of frames it takes to morph from one shape to another
- for text3d it is the number of times drawing a word before the next one

For others it means nothing. Bestie that is genuinely the entire list, I did not skip a single one 🫶.

-size num — the size option sets the size maximum size of a star in bouboule, pyro and star ⭐, size of ball in ball and bounce, size of bat in bat 🏏, maximum size of bubble in bubble, size of clock in clock, minimum size of rectangles in deco, size of the polygons in crystal, tik_tak, and toneclock, size of polyhedron in ico, size of lissie in lissie, size of dots of flag, for kaleid it is the symmetry, width of maze hallway, size of side of penrose tile, radius of loop in lisa, radius of ball in roll, number of corners in sierpinski, number of stars in scooter, size of tube in tube, width of worm in worm, line width in rotor, size of cells in ant, bug, dilemma, dragon, life, life1d, pacman, petri, tetris, voters, wator, and wire. In pipes it is the maximum length of a system. In flow and swarm it is the length of the lines. In atlantis it is the shark size 🦈. In mball it is the number of bands. In pyraminx, oct, and rubik it is size the puzzle. A negative number allows for randomness, similar to count 👀. In atunnels, fire, gears, sballs and sproingies it is the size of the screen (default 400), this is because on many slow systems it runs too slow when the picture covers the full screen. Set to 0 for full screen on fast machines 🔥.
-ncolors num — sets the maximum number of colors to be used. That's it, that's the whole vibe 🌈.
-saturation value — sets saturation of the color ramp used to value. 0 is grayscale and 1 is very rich color. 0.4 is a nice pastel 🎀 (pastel girlies stay winning).
-erasemode modename — as of this writing there are over 12 erase modes supported (if its not chosen its assumed random). The erase modes are random_lines, random_squares, venetian, triple_wipe, quad_wipe, circle_wipe, three_circle_wipe, squaretate, fizzle, spiral, slide_lines, losira, no_fade. modename is now similar to the option modelist where you can it can be something like "all-losira" to get all erasemodes but losira. Use a "+" or a "," to add modes like "spiral+venetian" ✨.
-erasedelay usecs — sets the number of microseconds for steps of the erasemode (a setting of 0 and the erasemode is bypassed) 💀.
+/-nolock — the nolock option causes xlock to only draw the patterns and not lock the display. A key press or a mouse click will terminate the screen saver. Lowkey just a vibe generator at that point 🦋.
-/+inwindow — runs xlock in a window, so that you can iconify, move, or resize it and still use your screen for other stuff 🫶. When running in a window, xlock no longer locks your screen, it just looks good. Main character energy, zero security ✨.
-/+inroot — runs xlock in your root window. Like the inwindow option it no longer locks the screen, it just looks good 🌸.
-/+remote — tells xlock 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 xlock locally. If you lock someone else's workstation, they will have to know your password to unlock it 🔐. Using +remote overrides any resource derived values for remote and prevents xlock from being used to lock other X11 servers. (Use + instead of - to override resources for other options that can take the + modifier similarly.)

ngl bestie, that remote one is a whole warning label. Read it twice 💀

-/+mono — causes xlock to display monochrome, (black and white) pixels rather than the default colored ones on color displays 🖤🤍.
-/+allowaccess — 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 allowaccess 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 xlock is killed -KILL, the access control list is not lost.
-vtlock modename — used on a XFree86 system to manage VT switching in [off|noswitch|switch|restore] mode:
- off — means no VT switch locking.
- switch — means VT switch locking + switching to xlock VT when activated.
- restore — means VT switch locking + switching to xlock VT when activated + switching back to previous VT when deactivated.
- noswitch — means VT switch locking only when xlock VT is active.
-/+allowroot — allows the root password to unlock the server as well as the user who started xlock 👑. May not be able to turn this on and off depending on your system and how xlock was configured.
-/+debug — allows xlock to be debugged by doing all but locking the screen 🔍. Fr fr the "do everything except the scary part" mode.
-/+description — causes xlock shows a mode description above password window. The default is to show this description.
-/+echokeys — causes xlock to echo '?' characters (default) for each key typed into the password prompt. Some consider this a security risk, so the default is to not echo anything 🙈.
-echokey echokey — the text character to use for echo key in echokeys.
-/+enablesaver — by default xlock will disable the normal X server's screen saver since it is in effect a replacement for it. Since it is possible to set delay parameters long enough to cause phosphor burn on some displays 🔥💀, this option will turn back on the default screen saver which is very careful to keep most of the screen black.
-/+resetsaver — by default xlock will call XResetScreenSaver. This may be undesirable with DPMS monitors.
-/+grabmouse — causes xlock to grab the mouse and keyboard, this is the default. xlock can not lock the screen without this 🖱️⌨️.
-/+grabserver — causes xlock to grab the server. This is not usually needed but some unsecure X servers can be defeated without this 👀.
-/+install — allows xlock to install its own colormap if xlock runs out of colors. May not work on with some window managers (fvwm) and does not work with the -inroot option.
-/+mousemotion — allows you to turn on and off the sensitivity to the mouse to bring up the password window 🐭.
-/+sound — allows you to turn on and off sound if installed with the capability 🔊.
-/+showdate — allows you to turn on and off the date on password window. On by default 📅.
-/+timeelapsed — allows you to find out how long a machine is locked so you can complain to an administrator that someone is hogging a machine 😤 periodt.
-/+usefirst — causes xlock to use the keystroke which got you to the password screen as the first character in the password. The default is to ignore the first key pressed.
-/+verbose — verbose mode, tells what options it is going to use 🗣️✨.
-nice nicelevel — sets system nicelevel of the xlock process to nicelevel.
-lockdelay seconds — sets the number of seconds before the screen needs a password to be unlocked. Good for use with an autolocking mechanism like xautolock(1) 🕰️.
-timeout seconds — sets the number of seconds before the password screen will time out.
-font fontname — sets the font to be used on the prompt screen 🎀.
-planfont fontname — option sets the font to be used for the text that is displayed in the lower part of the password screen.
-fg color — sets the color of the text on the password screen to color.
-bg color — sets the color of the background on the password screen to color.
-foreground color — sets the color of the text on the password screen to color.
-background color — sets the color of the background on the password screen to color.

yeah bestie -fg/-bg and -foreground/-background are literally the same thing twice, they said it, not me 💅

-username string — text string is shown in front of user name, defaults to "Name: ".
-password string — text string is the password prompt string, defaults to "Password: ".
-info string — text string is an informational message to tell the user what to do, defaults to "Enter password to unlock; select icon to lock.".
-validate string — text string is a message shown while validating the password, defaults to "Validating login..." ⏳
-invalid string — this is the message that shows when the password is invalid, and it defaults to "Invalid login." 💅
-geometry geom — sets geom as the size and offset of the lock window (normally the entire screen). The entire screen format is still used for entering the password. The purpose is to see the screen even though it is locked. Use this with caution, bestie: many of the modes will fail if the windows are far from square or are too small (size must be greater than 0x0). This should also be used with -enablesaver to protect the screen from phosphor burn. 🔥
-icongeometry geom — sets geom as the size of the iconic screen (normally 64x64) seen when entering the password. Use with caution: many modes will fail if the windows are far from square or too small (size must be greater than 0x0). The greatest size is 256x256. There should be some limit so users could see who has locked the screen. Position information of the icon is ignored. 🎀
-glgeometry geom — sets geom as the size of the screen for gl modes. Not normally available or needed. ✨
-/+wireframe — turns wireframe on/off, available on ant3d, atlantis, atunnels, daisy, fire, gears, lament, life3d, mountain, sballs, sproingies, superquadrics, and triangle.
-/+showfps — turns the frame per sec display on/off, available on atlantis, atunnels, bevel, dino, bubble3d, cage, fire, gears, invert, lament, moebius, morph3d, mball, oct, pyraminx, rubik, sballs, skewb, stairs, and superquadrics.
-/+fpstop — turns the frame per sec display on top of the screen on/off, used if showfps is on.
-fpsfont fontname — sets the font used in the frame per sec display, used if showfps is on. 🦋
-/+use3d — turns the 3d view on/off, available on bouboule, pyro, star, and worm.
-delta3d value — the space between the center of your 2 eyes for 3d mode. 👀
-none3d color — the color used for empty size in 3d mode.
-right3d color — the color used for the right eye in 3d mode.
-left3d color — the color used for the left eye in 3d mode.
-both3d color — the color used for overlapping images for the left and right eye in 3d mode.

⚠️ WARNING ⚠️

Okay so real talk: xlock can appear to hang if it is competing with a high-priority process for the CPU 😭. For example, if xlock is started after a process with 'nice -20' (high priority), xlock will take a considerable amount of time to respond. Not the vibe, but them’s the facts 💀.

🕶️ SHADOW PASSWORDS 🕶️

If the machine is using a shadow password system, then xlock 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 -cpasswd option, or in the file $HOME/.xlockrc, with the first taking precedence. In both cases an encrypted password is expected (see makekey(8)). If neither is given, then xlock will prompt for a password and will use that, also storing an encrypted version of it in $HOME/.xlockrc for future use 🫶.

🔐 XLOCK AND SSH-AGENT 🔐

If you use ssh-agent(1) to avoid entering a passphrase every time you use one of your ssh(1) private keys, it’s good security practice to have ssh-agent forget the keys before you leave your terminal unattended. That way, an attacker who takes over your terminal won’t be able to use your private ssh keys to log in to other systems. Once you return to your terminal, you can enter the passphrase and re-add the keys to ssh-agent.

There are a couple of ways in which xlock can help to automate this process. Firstly, the startCmd option allows xlock to be configured to run 'ssh-add -D' every time you lock the screen, so that your keys are automatically deleted from ssh-agent. If the passphrase on your ssh keys is the same as your password, then xlock can also be made to re-add the keys to ssh-agent when you unlock the screen, via the pipepassCmd option. This requires a bit of scripting, as the command must read your password from standard input and then automate the interaction with ssh-add to re-add the keys. There is an example of such a script in the xlock distribution - see etc/xlockssh* 🐚.

💀 BUGS 💀

Okay this one is serious, bestie. This:

"kill -KILL xlock "

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 xlock could not catch SIGKILL, it terminated before restoring the access control list. This will leave the X server in a state where "you can no longer connect to that server, and this operation cannot be reversed unless you reset the server."

-From the X11R4 Xlib Documentation, Chapter 7.

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 happen to run without "-allowaccess" on an NCD terminal, xlock 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 😭.
