OK .. if you run this as root, it will tell you what the actual video
card is what what driver and/or kernel module is in use:
for card in $(lspci | grep ' VGA ' | cut -d" " -f 1); do \
lspci -v -s $card; done
Here is an example output for my workstation:

With that info, you can troubleshoot the specific driver or kernel
module.

Johnny,
Thank you again for your help. As I mentioned before, I do not have a
video card on either of these machines, just the mother board along
with the cpu.
Here is the result of 'lspci -v -s 00:02.0' on both machines :

I have still not been able to totally figure out what is happening with
these (Intel(R) Core(TM) i7-7700) video displays that use the cpu and
not a video card, however I did identify a little more information.
One of of the units that has failed to generate a login screen at the
time of booting, I have two video monitors set in place, one is hdmi
and the other is vga; when I boot this machine with both monitors
attached to the motherboard video connections, I do not get a login
screen. If I unplug the VGA monitor and boot the machine I get the
login screen on the hdmi monitor. If I unplug the hdmi and use the vga
as a single monitor, I do not get a login screen.
If I boot with only the hdmi monitor attached, I get a login screen and
can login. After gnome3 is started I can then plung in the VGA monitor
and both will work normally.
Is this a problem with the 'i915' driver? Maybe it is time to fill out
a bug report??
Greg
