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