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.
