Booting up to black screen - Log included

[linuxnutster at videotron.ca]

Greetings,

I previously posted that since a fedup to fedora 21, I intermittently 
boot up to a blank screen. I'm using akmod-nvidia-340xx, but reverting 
back to nouveau did not solve the issue. One out of every 3 boot results 
in the problem. I pressed ctrl+alt+F2 and logged in and attempted the 
startx command. The resulting error message said to check xorg.1.log.

The nvidia console ( nvidia xserver settings ) clearly indicates my 
screen type ( Ancor communications Asus VH196. Would the "no screens 
found" be the possible source of my headache?

This is the error log from /var/log/Xorg.1.log:
