On the Console If you are using the Raspberry Pi solely on the console (no desktop GUI), you need to set the console blanking. The current setting, in seconds, can be displayed using

Here, consoleblank is a kernel parameter. In order to be permanently set, it needs to be defined on the kernel command line.

Add consoleblank=0 to turn screen blanking off completely, or edit it to set the number of seconds of inactivity before the console will blank. Note the kernel command line must be a single line of text.
