How to make CentOS 6.6 power off the console screen automatically?

On CentOS 6.6, I find that it can make the screen (console, not X) blank after a while. However, it does not power the screen off.

This usually work on Fedora or other releases. I guess this is caused by some configurations specific in CentOS 6.6.

You may try removing the nomodeset. It plays the trick for me.

What is nomodeset? It disables Kernel Mode Set (KMS). KMS moves the initialization of the graphics mode from the X server to the kernel.
