1 xlock locks the X server till the user enters their pass-
2 word at the keyboard. While xlock is running, all new
3 server connections are refused. The screen saver is disabled.
4 The mouse cursor is turned off. The screen is blanked and a
5 changing pattern is put on the screen. If a key or a mouse
6 button is pressed then the user is prompted for the password
7 of the user who started xlock.
9 If the correct password is typed, then the screen is
10 unlocked and the X server is restored. When typing the
11 password Control-U and Control-H are active as kill and
12 erase respectively. To return to the locked screen, click
13 in the small icon version of the changing pattern.
