[SOLVED] Quad Monitor with Plasma and 2 GPU'S is not working

ploprof · 2016-09-24 10:45:52

So Ive recently installed Arch on my desktop for the first time and Im trying to get my graphics to work,
My issue being that whenever I start Plasma my bottom 2 screens (connected via DP to a Maxwell Titan X) work totally fine however my top 2 (connected via DVI-D to a GTX 690) simply stay black and when I move the mouse over to them it appears as an X, I am not able to open windows or do anything on these screens.
I have been searching for hours on how to make this work and I guess its so hard to figure out for me because it is a very unique problem (im assuming).
any help would be appreciated
Link to my /etc/X11/xorg.conf http://pastebin.com/qVEhrYNJ
I originally posted this in Applications and desktop enviorment but im not sure if that is the right forum for it, and I am a newbie when it comes to arch. I dont know how to move threads so I apologize in advance to the mods about that.

That xorg.conf file appears to set a xinerama setup, using 3 gpu devices and 3 monitors.

please post lspci -k and xrandr output.

sorry I should have said this in my first post but the reason for 3 gpu's is because the gtx 690 is technically 2 gpu's in one package whereas the titan is just a single high end one

That's the answer i was afraid you would give.

TL;DR :
Nvidia is screwing you/linux hard and painful.

---------------------------------------------------------------------

Detailed answer.

You have very nice cards in your system, unfortunately Nvidia blocks you from using them to full capacacity .
The GTX 690 uses SLI to combine 2 GPUs into 1 device.

Nvidia readme chapter 28 wrote:

Hardware requirements
SLI functionality requires:
Identical PCI Express graphics cards
A supported motherboard (with the exception of Quadro Plex)
In most cases, a video bridge connecting the two graphics cards
SLI Mosaic Mode requires NVIDIA Quadro GPUs.

SLI Mosaic is unusable on your system.

Nvidia does offer another option with SLI setups , called Base Mosaic .

Nvidia readme, appendix B wrote:

Option "BaseMosaic" "boolean"
This option can be used to extend a single X screen transparently across
display outputs on each GPU. This is like SLI Mosaic mode except that it
does not require a video bridge connected to the graphics cards. Due to
this Base Mosaic does not guarantee there will be no tearing between the
display boundaries. Base Mosaic is supported on SLI configurations up to
three display devices. It is also supported on Quadro FX 380, Quadro FX
580 and all non-mobile NVS cards on all available display devices.
Use this in conjunction with the MetaModes X configuration option to
specify the combination of mode(s) used on each display. nvidia-xconfig
can be used to configure Base Mosaic via a command like 'nvidia-xconfig
--base-mosaic --metamodes=METAMODES' where the METAMODES string specifies
the desired grid configuration. For example, to configure four DFPs in a
2x2 configuration, each running at 1920x1024, with two DFPs connected to
two cards, the command would be:

nvidia-xconfig --base-mosaic --metamodes="GPU-0.DFP-0: 1920x1024+0+0,
GPU-0.DFP-1: 1920x1024+1920+0, GPU-1.DFP-0: 1920x1024+0+1024, GPU-1.DFP-1:
1920x1024+1920+1024"

emphasis by me.

A few years ago linux driver in Base Mosaic mode had no problems with a 2x2 setup, some even claim it could do 3x2 and 2x3 setups and higher using consumer grade hardware.
Windows however only managed to do that on Quadro cards. For consumer grade cards windows driver was limited to 2 cards and 3 monitors.
In order to have "feature parity" between linux and windows Nvidia articially limited the linux driver to 3 monitors on 2 cards.
Not to long after that, MS improved windows monitor / gpu support dramatically. Nividia windows driver could now do 2x2 and higher multi-gpu / multi-monitor setups on consumer grade hardware.
Nvidia never removed the limitation to 3 screens / 2 gpus for consumer hardware from their linux driver.

Well since these are technically 3 gpu's in one pc as you say could I at the very least use 3 of my screens 2 with the titan x and 1 with the 690-A ?
Also my nvidia-settings gui shows all the monitors http://i.imgur.com/cKfGkAN.png Perhaps 4 would still work with nouveau ?
I should mention that even though I can see all 4 in the settings gui the 2 dell screens on the side dont work with KDE and are just blank screens.

Hello!

Why do you whant to run one titan X and one 690 card, what do you hope to gain? According to the titan X specification you can run 4 displays with it.

Regards
Martin

Ploprof, it should be possible to use 3 monitors with nividia driver.
I even think both 1 monitor on Titan / 2 on 690 or 2 on Titan / 1 on 690 are doable.

The readme from nvidia is your best bet for info to get things working in base mosaic mode.
latest version is here : ftp://download.nvidia.com/XFree86/Linux … README.txt
