Hardware Accelerated NVidia and Intel Graphics Together in Debian

Question

I would like to use two xservers each running on a separate graphics card,in fact I'm using two monitors with two different graphic cards installed on my computer,like this :

root@ziomario-Z87-HD3:/home/ziomario# lspci -nn | grep VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK106 [GeForce GTX 660] [10de:11c0] (rev a1)

root@ziomario-Z87-HD3:/home/ziomario# lspci -nn | grep NVIDIA

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK106 [GeForce GTX 660] [10de:11c0] (rev a1)

01:00.1 Audio device [0403]: NVIDIA Corporation GK106 HDMI Audio Controller [10de:0e0b] (rev a1)

I'm reading this article.

and I have changed some command because there are differences between what he says to do and my situation. This is what I did :

Installed NVidia driver as root user with this command :

./NVIDIA-Linux-x86_64-340.32.run –accept-license –no-backup –no-x-check –no-questions –ui=none –no-x-check –no-distro-scripts –utility-prefix=/nvidia –installer-prefix=/nvidia –opengl-prefix=/nvidia –opengl-libdir=glx

made a libglx.so link in the /nvidia/glx directory for NVidia :

ln -s /usr/lib/xorg/modules/extensions/libglx.so.295.59 libglx.so

As root, created the folder /etc/ld.conf.d (it didn't exist before) with the file inside : /etc/ld.conf.d/nvidia with two lines pointing to the new library directories:

/nvidia/lib
/nvidia/glx

Ran this command as root to make the above paths active.

ldconfig

created the file /etc/X11/xorg.conf with the command

nvidia-xconfig

Used the ModulePath option to direct the nvidia xserver to the correct Glx. Added this to /etc/X11/xorg.conf in existing Files section as follows:

this is my xorg.conf file :

Section "ServerLayout"

Identifier     "Layout0"
Screen      0  "Screen0"
InputDevice    "Keyboard0" "CoreKeyboard"
InputDevice    "Mouse0" "CorePointer" EndSection

Section "ServerLayout"

Identifier     "Layout1"
Screen      0  "Screen1" 0 0
Option         "Xinerama" "0" EndSection

Section "Files"

modulepath "/nvidia/glx,/nvidia/lib,/usr/lib/xorg/modules"

EndSection

Section "InputDevice"

# generated from default
Identifier     "Mouse0"
Driver         "mouse"
Option         "Protocol" "auto"
Option         "Device" "/dev/psaux"
Option         "Emulate3Buttons" "no"
Option         "ZAxisMapping" "4 5" EndSection

Section "InputDevice"

# generated from default
Identifier     "Keyboard0"
Driver         "kbd" EndSection

Section "Monitor"

Identifier     "Monitor0"

ModelName      "Unknown"
HorizSync       28.0 - 33.0
VertRefresh     43.0 - 72.0
Option         "DPMS" EndSection

Section "Monitor"

Identifier     "Monitor1"
VendorName     "Unknown"
Option         "DPMS" EndSection

Section "Device"

Identifier     "Device0"
Driver         "nvidia"
VendorName     "NVIDIA Corporation" EndSection

Section "Device"

Identifier     "Device1"
Driver         "intel"
BusID          "PCI:0:2:0"
Option         "AccelMethod" "uxa" EndSection

Section "Screen"

Identifier     "Screen0"
Device         "Device0"
Monitor        "Monitor0"
DefaultDepth    24
SubSection     "Display"
    Depth       24
EndSubSection EndSection

Section "Screen"

Identifier     "Screen1"
Device         "Device1"
Monitor        "Monitor1"
DefaultDepth    24
SubSection     "Display"
Depth       24
EndSubSection EndSection

configured user LD_LIBRARY_PATH environment in the files (this can be set universally in /etc/profile and /etc/bash.bashrc configuration files instead): ~/.profile ~/.bashrc and,~/.xsession file by adding the following lines:

if [ echo $DISPLAY |grep -c ":1" -eq 1 ]; then export LD_LIBRARY_PATH=/nvidia/glx
fi

Reinstalled xorg packages with Glx so that damage from the previous NVidia install is corrected :

apt-get --reinstall install glx-alternative-mesa xserver-xorg-core libgl1-mesa-glx libgl1-mesa-dri

Restarted Gdm3

/etc/init.d/gdm3 restart

it didn't work. The monitor attached with the NVIDIA graphic card is working correctly but the other one,where is attached the INTEL graphic card is off...any suggest ?

Do you get a blank screen or a blank screen with a mouse pointer? I have almost the same hardware and use 2 xorg files, one for each seat and lightdm as desktop manager. The problem appears when I enable on seat1 (intel) the options

Section "ServerFlags" Option "AutoAddDevices" "false" Option "AutoEnableDevices" "false" EndSection

I need these options to limit mouses and keyboards on their respective seats.

And check this out in your xorg.conf:

Screen      0  "Screen1" 0 0

Are you sure the first "0" is ok?
