====== Project Ojective ======

The purpose of this project was to take the right half of the Video wall and create a 2 by 3 video wall to play Starcraft on. The project ended up using the whole video wall to support the Collage Art show from April 30 - May 14.

**Team members for this project where:**\\
Andrew Brundage-Briggs\\ 
Mike Gough\\
Jeffrey Jansen \\
Jamie Brant

**Hardware Requirements:**\\
6 Dells Desk Tops (wall01, wall02, wall03, wall04, wall05 and wall06)\\
12 Dell flat pannels \\

**Software Requirements:**\\
Operating system: Debian lenny and etch\\
window manager: fluxbox
Window manager startup script: startx\\
OpenGL clustering software: Chromium - Is a Application for interactive rendering on a clusters of workstations \\
Assumption is that wall01 is the master system\\

**Procedures used in this project:**\\
Debian install with window manager Fluxbox application : http://lab46.corning-cc.edu/user/jbrant/csit1320/project2
but instead of installing gnome as the window manger we installed fluxbox \\

NFS was also used, a procedure on how to install that can be found at: http://lab46.corning-cc.edu/user/jbrant/csit1320/nfs_install

===== The procedure used to create the Wall =====

==== OS and video driver install: ====
 
We started out by installing debian lenny on wall02, wall04, and wall06. a procedure for installing it can be found at  http://lab46.corning-cc.edu/user/jbrant/csit1320/project2 we will not preform the section on installing gnome.
instead we will do: **' aptitude install fluxbox '**

Next we installed the video driver: 
  * wget http://10.80.2.6/files/student/nvidia173.run 
  * chmod 777 nvidia173.run  
  * ./nvidia173.run  to install the driver. 
  * dpkg -l | grep nvidia ( gave use a list of files we needed to install) 
  * aptitude install (list of files)

====**Configuration of duel Monitors:** ====
On wall02 
edit the  /etc/Xll/xorg.conf \\

under 'Section Device '\\
make sure the following line exist.\\
	Driver	 “Nvidia”\\
	Option 	 “TwinView”	  “True”\\
Next
  * cd  /etc/apt
  * aptitude update
  * aptitude upgrade
  * scp /etc/apt/sources.list wall04:/etc/apt/
  * scp /etc/apt/sources.list wall06:/etc/apt/

Log on to wall04 and wall06 and do:

  * aptitude update
  * aptitude upgrade 

Back on wall02 
  * aptitude search xdmx
  * aptitude install xdmx xdmx-tools
 we copied the dmx.conf from wall01 to wall02 (wall02 was to be the controlling system) 

on wall02
made backup copy of dmx.conf\\
edit the dmx.conf  to:
<code> 
virtual vw0 2621x3372 {
     display tcp/10.80.1.72:0 2621x1024 @0x0;
     display tcp/10.80.1.74:0 2621x1024 @0x1174;
     display tcp/10.80.1.76:0 2621x1024 @0x2348;
 }
</code>

Edited /etc/X11/xorg.conf:
 changed the Section "Device"
  Section "Device"
        Identifier      "GeForce FX 5200"
        Driver          "nvidia"
        BusID           "PCI:1:0:0"
        Option          "TwinView"      "true"
        #Option          "MetaModes"     "1280x1024 +0+0, 1280x1024 +1388+0"
        Option         "MetaModes"     "640x480 +0+0, 640x480 +734+0"
  EndSection



changed the Section "Screen"


  Section "Screen"

                Modes           "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth           4

                Modes           "1280x1024"
        EndSubSection
Then copied it to wall04 and wall06
scp /root/dmx.conf wall02:/root copy to wall04 and copy to wall06
scp /root/wallup wall02:/root

scp /root/playificate
scp /root/bigify

aumix
aptitude search aumix
aptitude install aumix
aumix
aptitude search alsa
aptitude install alsa
alsaconf

once we got the wall up and running on all three system with wall02 controlling them we started with the chromium

==== Chromium_install ====


  * step 1. wget http://sourceforge.net/projects/chromium/files/Chromium-source/Chromium%201.9/cr-1.9.zip/download
  * step 2. unzip cr-1.9.zip
  * step 3. mv gmake /usr/bin/
  * step 4. ln -s gmake /usr/bin/make
  * Note : The next few lines will be repeated a number of times
  * step 5. Make 2> chrom-error
  * step 6. view chrom-error
  * step 7. aptitude search mesa
  * step 8. aptitude install Libgl1-mesa +-dev

do steps 5 thur 8 for each of the following 

In step 7 replacing 'mesa' with each of the following options:
   * glu
   * Xmu
   * glut
   * GL
   * xlibmesa
   * jpeg62

In step 8 replace “Libgl1-mesa +-dev” with each of the following: 

   * xlibmesa-glu xlibmesa-glu-dev
   * libxmu-dev libxmu6 libxmu-headers
   * libglut3 libglut3-dev
   * libgl-dev libgl1 libgl1-mesa libgl1-mesa-dev libgl1-mesa-dri
   * zlib1g-dev libxi-dev libjpeg62-dev 

cd root/cr-1.9/lib/Linux  \\
ln -s libcrfaker.so libGL.so.1\\\
ln -s libGL.so.1 libGL.so
