There are probably Fn keys (Fn & F4 usually) for cycling between monitor options. This always requires a connected monitor and usually a reboot. Hit it from startup until the kernel loads the video module, or until the monitor comes on

install arandr or grandr (although fedora most probably has it's own gui for that) and see if the monitors are detected AND active.
if that does not help, post the output of
Code:
xrandr

Ok so I did a little bit of testing as I am in the process of finding a suitable replacement for Ubuntu, I tried to install Fedora with gnome and both monitors were recognized but when I tried to do it with xfce well things went down the drain, so ok I thought to my self try out another distro and see will it work, installed Debian 7 with no gui and than installed xfce latter on, same problem, I do believe that the problem is not the OS but rather instead xfce DE.

xrandr

XFCE doesn't really do the graphics. Bios, kernel, and X drivers are involved. XFCE is only a window manager. IMHO, you are better staying with a distro you like and sweating through the configuration of it rather than wiping and restarting.

Something always lands 'jammy side down', and you just need to correct it.
