2 nvidia gpus with 3 monitors - no xorg.conf

Postby ejones1025 on Thu Apr 12, 2012 8:52 pm

For several weeks I have tried to get my LDME system to allow use of 3 monitors- (2) - 20" DVI monitors and (1) - 32" HDTV. I have read and tried every debian, linuxmint and ubunta suggestion I could find with out success. Most google searches find my first request for help. This is the second request.

System:

Motherboard - ECS Black Series A785GM-AD3(1.0) AM3 AMD 785G ATX AMD Motherboard

CPU - AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor

RAM - 2 x G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory

GPU1 - EVGA 01G-P3-1431-KR GeForce GT 430 (Fermi) 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card with 2 Samsung 20" monitors.

GPU2 - ZOTAC GT218IONGPU-A-E GeForce GT 218 (NVIDIA ION graphics processor) 512MB DDR3 PCI Express x1 with 1 Toshiba 32" HDTV

Hard Drives: SDA - 1TB with Windows 7 Ultimate (700GB) and Dual Boot LinuxMint Release 1 (debian) Kernel Linux 2.6.39-2-amd-64 (262 GB)

SDB - 1TB - Backup of SDA

SDC - 1TB - Common Data - multimedia (movies, music and tv programs)

Power Supply - 850 watt

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

Current Status:

Win7 Ultimate -
setup for both monitors and HDTV - each screen can be adjusted seperately. I can drag program window to any of the three monitors.

LDME -
Dual Boot - no problems. System is updated.
Monitors - the monitors attached to GPU1 work as expected. (drag program windows to either monitor) HDTV attach through HDMI on GPU2 will not work. runing xrandr gives this information:

$ xrandr
Screen 0: minimum 320 x 200, current 3200 x 900, maximum 8192 x 8192
DVI-I-1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 443mm x 249mm

640x480 72.8 75.0 66.7 60.0
720x400 70.1
HDMI-1 disconnected (normal left inverted right x axis y axis)



Seems the second GPU is not found. Currently using the Nouveau drivers. Attempts at installing latest nvidia drivers has failed - no matter who's instructions I followed.

There is no "/etc/X11/xorg.cong" file. Creating xorg.conf kills X.

I would be happy to have the 2 monitors working and the HDTV as a clone of one of them -- NO JOY SO FAR.

Thanks for any help or suggestions

Now that I am in the right place --- Thanks!

Again I am trying to get the nvidia drivers installed. This is what I did and the results.

First I removed nouveau as it conflicts with nvidia
# apt remove xserver-xorg-video-nouveau
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
xserver-xorg-video-all xserver-xorg-video-nouveau
0 upgraded, 0 newly installed, 2 to remove and 6 not upgraded.
After this operation, 545 kB disk space will be freed.

Trying to follow your instructions located here:

I get these results:
# apt-get install nvidia-kernel-dkms nvidia-glx build-essential nvidia-settings nvidia-xconfig

build-essential is already the newest version.
nvidia-kernel-dkms is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
nvidia-glx : Depends: xorg-video-abi-6.0 or
xserver-xorg-core (< 2:1.7.7) but it is not going to be installed
E: Broken packages


To isolate the problem I did this next:
# apt-get install nvidia-glx
Reading package lists... Done

Then this:
# apt-get install nvidia-glx${2.6.39-2-amd64}
bash: nvidia-glx${2.6.39-2-amd64}: bad substitution


Now I am restoring the new install ---------------------

Problem has to be with the driver installation as I had similar results trying to setup Ubuntu kubuntu and opensuse. Debian Squeeze was worse.

Still looking for any suggestions

Problem is you don't know exactly how to install versions and dependencies.

Code: Select all
xserver-xorg-core (< 2:1.7.7)
This means you have to find a version of XServer below 2:1.7.7

I don't know if downgrading XServer is an easy task and I'm not sure that this will even fix your initial problem.
The version you are searching is in Stable. You had to change your repositories. #1.a) viewtopic.php?f=197&t=91405
But this sources.list seems to be more up to date: viewtopic.php?f=197&t=91405&p=566361#p551063

There is no "/etc/X11/xorg.cong" file. Creating xorg.conf kills X.

You mean even just creating the file kills X?
Code: Select all
sudo touch /etc/X11/xorg.conf

Or could you give us the files you tried?

Have you tried asking on Nvidia forums (http://www.nvnews.net/)?

Computers is not science. And it's not magic - it's something in between.
