Hi Sorry to barge in.
How do I do that? Do you have a link I could go to and learn how to do it?
I have a KVM and whenever I switch from Fedora to the other PCs, I start
getting a bunch of lines on the journal complaining that the system could
not get the EDID info:
"nvidia-modeset: WARNING: GPU:0: Unable to read EDID for display device
VGA-0"
Thanks
