sflock - simple feedback screen locker
Simple screen locker utility for X, based on slock. Provides a very basic user feedback.
In order to build sflock you need the Xlib header files.
Arch Linux users can install this package from the AUR(http://aur.archlinux.org/packages.php?ID=44802).
Manual installation: Edit config.mk to match your local setup (sflock is installed into the /usr/local namespace by default).
Afterwards enter the following command to build and install sflock (if necessary as root):
make clean install
Simply invoking the sflock command starts the display locker with default settings.
-b: toggle the bar. -f : modify the font. -c : modify the characters displayed when the user enters his password. This can be a sequence of characters to create a fake password.
