Along with looking at
https://www.kernel.org/doc/Documentation/EDID/
as pointed to by Tom, you should also look at
https://wiki.archlinux.org/index.php/ kernel_mode_setting#Forcing_modes_and_EDID
Basically, because you have a KVM that doesn't relay the EDID data from
the monitor to the kernel faithfully you'll need to override it. The
link above gives information on how to do that. The hard part can be
getting the actual EDID information from your monitor to place in
/usr/lib/firmware/edid .
I did cd /usr/lib/firmware, followed by ls|grep edid -- first as
user, and then as root. No hits either way. Does that mine is elsewhere?
Or that its absence *is* the problem?
If the latter, can I simply put the
kernel.org file into /usr/lib/
firmware? And uncomment -- what? All of it?
I only have experience doing that with nVidia
binary drivers where it is easy to do with their nvidia-settings
utility. There is a monitor-edid package available which supplies
monitor-get-edid which may or may not work. If you install it, you'll
probably find it gets a selinux error which you can fix easily. But it
won't work for me after that but that may be due to my choice of
drivers.
Remember I know precious little (beyond the jargon -- I'm a
linguist, after all). Messing with anything kernel-related OR selinux-
related sounds to me like a minefield for fools. "Here, hold my beer ...."
Anyway, something like this happened to me quite some time ago. I
found
the least painful thing to do was to research and then go out and buy a
good KVM. I no longer have the need for KVM so I can't recommend a
product. But that is what I would do. Not only would it solve the
problem for me with the least amount of pain/effort I wouldn't have to
go through the same process in the event of a fresh install or another
reason.
That sounds best for me, too; so I have asked my go-to LUG. Many
many thanks!!
