I got a used asus desktop computer and monitor and I fully installed Fedora 20 on there. There are 2 vdi-d inputs on the computer. When I first tried to install it I was using a monitor with a dvi-d to HDMI adapter. With this adapter I would only be able see the opening "asus" screen when it started up along with the boot menu and BIOS then it would go blank once the OS would begin.
I found a monitor with a dvi-d input and I used that monitor instead with the proper chord (no adapter to hdmi) and it worked perfectly. I was able to install and run fedora 20 for a couple of days no problem.
Today I installed flash using these instrucions:
to allow me to watch videos online. the video froze and now when I reboot it does not recognize the monitor I had been using with the correct dvi-d cable. It only recognizes it at when it boots up along with the BIOS and boot menu then it rejects it. It does, however recognizes the other monitor that has the adapter.
I need help on some possible issues that may cause this and how to fix it. I am still able to access fedora 20 but with the older monitor that is not too good
