Centos7 Turn off Screen saver

Online query, many of the command "Setterm-blank 0" method to turn off screen protection, but I tried to find no effect, screen protection still exists.

Depending on the parameters in the query setterm command, I think it should be the-powersave option in the Setterm command.

Then try to use the following command:

Setterm-powersave off

However, when you run the command, the command line interface outputs the following error message:

Setterm:cannot (un) set powersave mode:inappropriate IOCTL for device

It may not be possible to set the command line in the graphical interface mode, but the graphical interface can be used to turn off screen saver as follows.

Graphical interface Mode method:

1. Click the menu bar Application-system tools-setting, click the Power icon in the hardware area in the Setting dialog box.

2. In the popup dialog box, set the blank screen drop-down box for the power saving area to "never".
