Situation:
Using one of these "HDMI VGA DVI LCD Control Board For LP154WX4 LP154W01 N154I2 1280x800 LCD Screen" and hooking up my CentOS 7 Desktop via VGA cable to my old laptop monitor using this control board. I can see the terminal and type commands and everything.
The problem is the terminal outputs this message over and over again every 5 seconds or so, even when using nano or when in the middle of typing a terminal command. (beginning number changes with each output):
[ 35.418845] [drm:radeon_vga_detect [radeon]] *ERROR* VGa-1: probed a monitor but no:invalid EDID
What I've got so far:

I found a reasonable answer.
1) Typically EDID error message may be simple because of VGA cable problems. I found that other monitor works w/the same cable normally, therefore it's a monitor problem.
2) It's only EDID data problem - I works normally w/this monitor under Windows 7.
3) It's possible to suppress EDID work w/X11 . It's necessary simple to put to /etc/X11/xorg.conf.d the configuration file with
Option "Ignore EDID" "1" Modes "1366x768" ... "800x600"
Which I don't think is applicable to CentOS 7.
And this Radeon DVI errors filling logs which is a solution for debian-wheezy.
Question:
What do you recommend to do? Any ideas on how to make it into a valid VGA connection or suppressing the terminal outputs?
Thanks.
