#CMOS CHECKSUM INVALID HOW TO#
The monitor works just fine, so I'm hoping someone can please tell me how to get the system to shut up about this EDID Checksum - otherwise it occasionally spits the message out while I'm working on system config, scanning, etc. There is a DVI port on the video card, but it is not used. I'm just using a plain OLD VGA monitor because this system is in a comm closet and no one looks at the screen.
I'm frustrated because the only help I can find involves changing the X config file, which is obviously not the solution I need. I have absolutely NO X-Windows installed on the system, so please don't tell me to change /etc/X11/nf since that file DOES NOT EXIST.
I'm getting errors like this: ] *ERROR* EDID checksum is invalid, remainder is 209ĭuring and shortly after booting my Ubuntu Server 16.04.3 system.
