[clug] GDM blanking in redhat 8

[Geoff Smith]

Hi folks,

In redhat 8, using GDM to manage the login screen, the screen will go 
blank after a few minutes of just sitting there before anyone logs in.

How can I make it stop doing this? I want the logon screen to always be 
visible when someone isn't logged on.

Once you login, there are no screensavers enabled and it doesn't blank 
at all.

Any clues?

Cheers,

Geoff
