RHEL 7.3, 4-nVidia P2000 with 4 monitors, only one monitor working
Hi All,
I have installed RHEL 7.3 and am trying to install nVidia graphics drivers to support 4-nVidia P2000 cards with a monitor attached to each. Right now, either I get graphics on one monitor or I get garbled graphics on all 4. I have tried various methods I have come across when I have googled the problem...not installing the nVidia driver and using the native drivers found in elrepo kernel; run yum update, use the default kernel and disable the nouveau driver and just about everything in between.
This a customer pre-sales question. The customer insists on 7.3 and I have to demonstrate that all 4-P2000 cards will work in the system we are quoting.
Any help would be greatly appreciated.
Thanks,
Bill

Hi Bill,
Unfortunately your question isn't easy to answer, everything depends on the individual hardware setup of your customer.
In the case you described I recommend to install the latest stable original NVIDIA drivers supporting the Quadro P2000.
You can choose either the drivers 390.77 from the long-lived branch or the drivers 396.51 from the short-lived branch.
Most important to get all those four monitors working is the correct configuration of the /etc/X11/xorg.conf file.
Please carefully read the instructions and then try out which configuration works, a "general how to do" doesn't exist.
And one thing : don't give up too fast, all has to fit, sometimes it takes a little while - but in the end it mostly works. :)

Hi Bill,
The nouveau drivers are the open source drivers variant for NVIDIA graphics adapters. You are able to "demonstrate that all 4-P2000 cards will work in the system ..." right as required from your customer and when you say it's working with them, why trying to install and configure the proprietary drivers then ? Now good luck with the other projects. :)

We've made 3 monitors work with both NVidia and nouveau drivers. That being said, ask them if they happen to have a current working edition of RHEL (any version) working with that specific graphics card, if yes then ask them if there is a copy of the /etc/X11/xorg (xorg.conf or backup files) available at least as a reference point. Older xorg.conf files sometimes have clues as to how it was previously set up. These might not be available, but it's worth seeing if they do exist.
Perhaps ask them if you provide a hard drive if you can perform a manual load of RHEL (you can get a free developer's edition of server at developers.redhat.com and select "server with gui" when you install that.
The best way I've seen in the numerous platforms with various customers to test if a specific NVidia card can be loaded is to try it, and make sure to have someone experienced doing the test with NVidia because that helps. We've not entered the usual set of pain (in terms of actual instructions) in these posts so far.
And note back in 2017 NVidia apparently added support for that card, this is the link, USE THE UPDATED VERSION NOT THIS LINK ---SEE LINK IN NEXT PARAGRAPH*** which is only here to show they added it in 2017. Perhaps ask them if you can go on their site and load it even as a trial run.
I'd attempt nouveau first just to see out of abject curiosity if it worked, and then try NVidia.
Based on NVIDIA's support pages, I suspect (can't confirm, try it) it "ought" to work. Your actual mileage may vary
