Hi,
I am troubleshooting a second monitor issue on my laptop. I recently upgraded my P51 to Fedora 30. The upgrade went well and plugging in a second monitor to the HDMI port worked well also. Recently, the second monitor is no longer detected when I plug it in and I cannot point to any specific change that may have caused that since I do not always have a second monitor connected. The laptop primary display works fine.
To check if it was a hardware or software issue, I rebooted to Windows – no problem with the second monitor there. I also booted a Fedora 30 install USB stick and the second monitor works there as well. This leaves me with the idea that the currently installed Fedora 30 cannot/does not detect the monitor on the HDMI port and that the problem lies therein.
My question is what should I do to figure out what problem is and how do I fix it? I have spent the last several days searching out solutions via Google etc. So far nothing works. I’d rather not reinstall Fedora if I can fix what is not working properly. Everything else with the Fedora 30 works well, it is just the inability to use the second monitor that is broken. While I have back ups of my files, a reinstall seems overkill and does not help me learn anything new.
Below I am posting the output from a few diagnostics. I hope some of this will provide a clue for a path forward.
