After a few minutes of inactivity, GNOME puts a sort-of curtain on the screen which has to be swiped upwards before the desktop is revealed again. Is there any way to suppress this 'feature' ?

You can change if screen lock is used under settings (from top right menu settings button in gnome-shell or gnome-control-center manually) Privacy options Screen Lock choice. That might already be off if you only get curtain, not a password prompt with it too. By clicking on that row, you also can change if notifications are shown in that locked state (meaning possibly private notifications can be seen without typing password) and if the screen is locked automatically after screen is turned off.

You can choose if screen is turned off (DPMS powersaving mode) on idle in Power options (Blank screen).

Note that the Gnome devs in their infinite wisdom limit the choices for blanking (in the Power settings GUI) from never to only 15 minutes. Fixed by eg.:
Code:
gsettings set org.gnome.desktop.session idle-delay 1800

where the value 1800 is seconds, half an hour in this case.

Usually if more than 15 minutes is needed, there's actually some bug somewhere. For example if it happens while watching video, then the player might not properly be inhibiting the lock, etc.
That said, thanks for pointing out how to make it be longer regardless :)

In Privacy > Screen lock there's the option "Lock screen after blank for". It can be set to a value up to 1 hour.

Also there's a GNOME extension called Caffeine that provides an icon on the top bar for temporarly inhibiting the blank/lock screen. I use it all the time.

Thanks all. It was the screen saver. I don't know how a static picture saves your screen, but that's what it was.

There's no static picture other than for a short while after it locks if locked manually. The screens should go to DPMS sleep within a minute or so. GNOME doesn't do any fancy screensaver animations and stuff, as that doesn't save modern screens from some sort of CRT burn-in.
