XTRLOCK(1)XTRLOCK(1)NAMExtrlock - Lock X display until password supplied, leaving windows visi‐
ble
SYNOPSISxtrlock [-b]
DESCRIPTIONxtrlock 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 touch‐
ing a key (Shift, for example) or the mouse.
OPTIONS-b blank the screen as well as displaying the padlock
X RESOURCES, CONFIGURATION
None.
BUGS
Additional input devices other than the keyboard and mouse are not dis‐
abled.
The timeouts, bitmaps and mouse cursor colour cannot be modifed.
