Black second screen after pure fedora 34 installation. It named as Unknown display in Settings. And resolution is bad too.
Main monitor is connected by DVI to nvidia 1050ti, it’s 1920x1080 and works fine for now. Additional monitor is connected by VGA to integrated intel graphics, it’s 1280x1024 and black, but i can move cursor to it.
Here is sudo lspci -v
