I’m a NixOs newbee! I have installed NixOS 23.11 under VirtualBox 7.0. Unfortunately, I have not yet succeeded in getting my second monitor to run. I have already defined two monitors in the VirtualBox settings. Unfortunately, after starting NixOS the item Display->Virtual Monitor 2->Activate is grayed out. Do someone have any idea what I could do here?
Here’s the output of the xrandr command:
