Hello,
I have a fresh installation of CentOS 7.5.1804. Graphical installation was performed using a single DP cable (No graphics were possible with both DP cables attached) and the integrated nouveau drivers that ship with CentOS.
After first boot and setup, I proceeded to blacklist the nouveau drivers and install the NVIDIA proprietary drivers (396.24), and connect both DP cables from the Graphics card to the Dell 8K monitor.
-----------------------------
INSTALL NVIDIA DRIVERS
yum -y install gcc
yum -y install kernel-devel
yum -y install epel-release
yum -y install dkms
Edit /etc/default/grub. Append the following to “GRUB_CMDLINE_LINUX”
rd.driver.blacklist=nouveau nouveau.modeset=0
Generate a new grub configuration to include the above changes.
grub2-mkconfig -o /boot/grub2/grub.cfg
Edit/create /etc/modprobe.d/blacklist.conf and append:
blacklist nouveau
Backup your old initramfs and then build a new one
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)
reboot
init 3
systemctl isolate multi-user.target
sh nvidia.NVIDIA-Linux-x86_64-396.24.run
reboot
no graphics to monitor!
tried switching back and forth between graphical.target and multi-user.target with various tweaks to xorg.conf to no avail.
also ran nvidia-xconfig to no avail.
Here is my current (non functional xorg.conf):

Does anyone have a functioning xorg.conf file they could share?
Thanks
