Third monitor issue

Hi, I added an amd HD2400 pro card to an existing onboard intel hd4600 system with two monitors, so i can add a third

the third monitor initalizes, but I get a blank screen on the login screen and system is very unresponsive,

Any ideas please how to troubleshoot further, which logs to collect/view?

running latest fedora 42 kde

thanks

oh well back to windows11, minitor setup works fine with it :slight_smile:
