XTRLOCK(1) XTRLOCK(1)
NAME
xtrlock - Lock X display until password supplied, leaving windows
visible
SYNOPSIS
xtrlock
DESCRIPTION
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 mouse.
OPTIONS, X RESOURCES, CONFIGURATION
None.
BUGS
Additional input devices other than the keyboard and mouse are not
disabled.
The timeouts, bitmaps and mouse cursor colour cannot be modifed.
