       xtrlock - Lock X display until password supplied, leaving windows visible


       xtrlock [-b]


       xtrlock locks the X server till the user enters their password at the keyboard.

       While  xtrlock is running, the mouse and keyboard are grabbed and the mouse cursor becomes
       a padlock.  Output displayed by X programs, and windows put up by new X clients,  continue
       to be visible, and any new output is displayed normally.

       The  mouse and keyboard are returned when the user types their password, followed by Enter
       or Newline.  If an incorrect password is entered the bell is sounded.  Pressing  Backspace
       or  Delete  erases  one  character of a password partially typed; pressing Escape or Clear
       clears anything that has been entered.

       If too many attempts are made in too short a time further keystrokes  generate  bells  and
       are otherwise ignored until a timeout has expired.

       The  X  server  screen saver continues to operate normally; if it comes into operation the
       display may be restored by the usual means of touching a key (Shift, for example)  or  the


       -b     blank the screen as well as displaying the padlock




       Additional input devices other than the keyboard and mouse are not disabled.

       The timeouts, bitmaps and mouse cursor colour cannot be modifed.
