On CentOS 7 I'm running into an issue with the latest nvidia driver
from elrepo: kmod-nvidia-384.98-1.el7_4.elrepo.x86_64
This driver version seem to introduce issue in detecting video modes
when a monitor is connected using DVI. As soon as the machine attempts
to start X, nothing happens and the monitor goes into sleep mode
reporting that it has 'no signal'.
It is interesting because it occurs with several monitors, but only
when they are connected through DVI. When using VGA it works like a
charm.
Also it did work without problems with the previous driver version
(kmod-nvidia-384.90-1.el7_4.elrepo.x86_64), with the exact same setup.
In this case the issue occurs with an Nvidia NVS 315. I don't know if
other nvidia cards are affected.
I can confirm that this happens with the driver downloaded from NVIDIA.
I had to fall back to the .90 driver to get it to work for all my
NVS 315s (with dual DVI) running on 7.4 / 6.9.
Thank you for the confirmation. I found a similar report on debian also
relating to NVS315 with the 384.98 driver so I'm guessing this is
hardware specific:

I couldn't find any reports upstream at nvidia so am unsure if they are
aware of the issue. For reference, my GK208 [GeForce GT 730] in my test
system is unaffected by the issue and is working fine with the 384.98
driver over DVI.
There is an updated version 387.34 short-lived branch driver available
in the elrepo testing repository that you could test to see whether the
issue has been fixed in this latest release (only available for el7
currently).
