xset +dpms server does not have extension for +dpms option

**When I run the command xset +dpms I get the error message server does not have extension for +dpms option. How can I fix this?** I've recently freshly installed Fedora 41 on my Thinkpad. Before under Fedora 40, I configured a keyboard shortcut to turn off the monitor via bash -c 'sleep 0.1 && xset dpms force off'. This doesn't work on the new installation. So, I tried xset +dpms which resulted in bash: xset: command not found... Install package 'xset' to provide command 'xset'? [N/y] which I answered by y. * Waiting in queue... * Loading list of packages.... The following packages have to be installed: xset-1.2.5-6.fc41.x86_64 User preference utility for X Proceed with changes? [N/y] y * Waiting in queue... * Waiting for authentication... * Waiting in queue... * Downloading packages... * Requesting data... * Testing changes... * Installing packages... server does not have extension for +dpms option Then, when I was running xset +dpms I got the error message server does not have extension for +dpms option. How can I fix this? PS: bash -c 'sleep 0.1 && xset dpms force off' obviously also doesn't work: bash -c 'sleep 0.1 && xset dpms force off' server does not have extension for dpms option xset: unknown option force usage: xset [-display host:dpy] option ...

So, how can I use DPMS to turn off my screen using Wayland (GNOME, Fedora 41) such that computations are not interrupted but the screen is turned off? And once I press a key the monitor should turn on again.
