Hi folks:
My goal is to enable Unity 3D in 12.04 from a machine having two monitors respectively connected to two nvidia Video cards, and one of the monitors rotate clock wisely . However, I found it is really hard. so far what I can achieve is to have dual screen in Unity 2D with one rotated monitor by using the following script:
$ sudo gedit /etc/X11/xorg.conf
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "1"
EndSection
Section "ServerFlags"
# Not working with Xinerama anyways.
Option "RandR" "on"
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"

EndSection
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"

EndSection
Section "Monitor"

Option "TwinView" "1"
Option "TwinViewXineramaInfoOrder" "DFP-0"
Option "metamodes" "nvidia-auto-select +0+0"

Option "metamodes" "nvidia-auto-select +0+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
Section "Extensions"
Option "Composite" "Disable"
EndSection
the problem of this setting is:
1. only working in Unity 2D
$ echo $ DESKTOP_SESSION
ubuntu-2d
2. nothing comes up when execute
$ /usr/lib/nux/unity_support_test -p
Error: no composite extension
3. $ ps -ef | grep compiz | grep $ USER
chenming 2547 2380 0 20:15 pts/1 00:00:00 grep –color=auto compiz
3. compiz does not work, either.
I also saw my colleague using the following script to enable unity 3D in 12.04 from a machine with dual screen without rotating
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
Option "Xinerama" "0"
EndSection
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "Unknown"
ModelName "DELL U2312HM"
HorizSync 30.0 – 83.0
VertRefresh 56.0 – 76.0
Option "DPMS"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "Quadro 4000"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "1"
Option "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1920+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
but clearly the difference between his machine and mine is that he has got one video card with two sockets, therefore only one device is defined, and dual screen can be achieved by TwinView rather than Xinerama. But in my case all of the devices, monitors has to define twice. and so far as I know it might not working by using TwinView. Also I didn’t know whether TwinView can rotate screen. Is there any way i can do to enable unity 3d in my machine with two video cards and screens? thanks a lot!
