.Sh SECURITY CONSIDERATIONS
To make sure a locked screen can not be bypassed by switching VTs
or killing the X server with Ctrl+Alt+Backspace, it is recommended
to disable both in
.Xr xorg.conf 5
for maximum security:
.Bd -literal
Section "ServerFlags"
Option "DontVTSwitch" "True"
Option "DontZap" "True"
EndSection
.Ed
.Sh CUSTOMIZATION
.Nm
can be customized by creating a custom config.h from config.def.h and
(re)compiling the source code.
This keeps it fast, secure and simple.
