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

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 :

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630

After doing some google searches I found the results of 
'hwinfo --gfxcard'  
on both machines (with some small differences) to be :
