On Linux Mint 17.1, the screen blanks when left idle. To stop this from happening, I have checked all the obvious candidates on the Power Settings and Login Window screens.

Can anyone help me figure out how to stop the screen from going black at an idle login prompt?

  • By "idle login prompt", do you mean a text mode console login, or a Display Manager login window?

Check screensaver. Normally it's set for a minute on new installs.
