I had a working Fedora 24 box for almost 2 years that I decided to
upgrade to FC 27. I have 3 monitors and used a 3 way adapter from
StarTech to adapt the single display port from my Intel NUC to support
my 3 displays. Again this worked fine for years. After the upgrade
this setup stopped working.
My system has an encrypted root and home partition, and an
un-encrypted boot partition. When I power on the computer with the 3
way adapter I get bios screens and the grub menu. If I select the old
FC24 kernel to boot, the system proceeds to the password screen where
I unlock my root partition, and then to the user login screen for
fedora. But if I select one of the new FC 27 kernels on the grub menu
I get a black screen only, no password screen to un-encrypt. If I use
a straight through DisplayPort cable to power only one screen, the new
Kernels work fine and I can unlock and login.
Also, adding *nomodeset* to the kernel boot options will allow the new
kernels to work with the adapter, but all 3 screens mirror and
performance is way down. I think this option doesn't use Intel's
drivers?
I looked at Xorg vs Wayland as a possible cause, but the option to
select that is on the user login screen, would that have any effect on
the un-encrypt password screen just after grub?
My graphics are Intel Iris 6100. My hardware is an Intel NUC with i7
processor. Video card is on chip.
So I am stuck. Please help?

I made sure my Intel drivers where fully updated =
