1. Install the same operating system on both machenes. Setup intstallation, setting names, passwords, ect.

1. Update. * ' aptitude update '
2. ' aptitude upgrade '
3. Install video driver. We used; wget http://10.80.2.6/files/student/nvidia173.run (because we already had this on the lab server)
   • chmod 777 nvidia173.run ; to compile the driver
   • ./nvidia173.run ; to install the driver. We ran into some problems here. To get around them we used 'aptitude install build-essential' and aptitude install linux-sorce-2.6.31 to bring the system up to date.
   • Using the dpkg -l | grep nvidia we found all the nvidia files we needed too, and installed all files that showed up with aptitude install

• In the xorg.config file we needed to edit Nvidia to nvidia, and uncomment NoLogo and TwinView lines.

' scp /etc/X11/xorg.conf 10.80.2.194 '

           
- Next we needed to install Fluxbox to have a window manager; ' **aptitude install fluxbox** ' on both systems
           * To set the screens to either act verticly or horizantly under the /etc/X11 directory we needed to edit the xorg.conf file on both systems. Under the "device" section we need to add   **Option "MetaModes"      "1280x1024 +0+0, 1802x1024 +0+0"** 
           * 
- Use **xhost +** to enable network communitcations on both machines.
- Use export** DISPLAY=10.80.2.194;0** to set the monitors of the second machine to display what is on the first machine.
- Installing Xdmx by using **aptitude install xdmx**, on both machenes. (Make sure both machenes are set to the same resolution)
- At this point we where able to launch the fluxbox desktop on both systems.
- Then we created a confiuration file that looked like this. 
              startx -- /usr/bin/X11/Xdmx:1 -display 10.80.2.199:0 -display 10.80.2.194:0 -ignorebadfontpaths + xinerana
        
- Patch Xdmx. We retrived the new patches from [[https://launchpad.net/ubuntu/karmic/+source/xorg-server/2:1.6.4-2ubuntu4.2]] (xorg-server_164.org.tar.gz and xorg-server_1.6.4-2ubuntu.4.2.diff)
- To patch files and output any errors to an error file, patch -p1 <xorg-server_1.6.4 2>err 
- All of those patched files should be in the /home/vidwall/xorg-server-1.6.4 directory
           * config, glx, debian, hw, doc, xkb (all of these should be in the zorg-server-1.6.4 directory)
- To compile these dpkg-buildpackage -rfakeroot -us -uc
           * Remove old files by aptitude remove xdmx (should remove both xdmx and xdmx-tools
           * To install new, dpkg -i packagename

At this point we should have had a working system, but we did not. This is what else we tried.

• We tried to download and install “dmxpict.patch” from the notes page of this wiki, under systems and networking.
  • in xorg-server-1.6.4/hw/dmx/dmxpict.c edit the file
  • between the line “FIX ME: Handle savng clip region ~” and “DMX_WRAP(Change Picture ~)”
  • XRectanle aRect;
  • aRect.x = 0; aRect.y = 0;
  • Arect.width = 9999 ;
  • ARect.height = 9999;
  • XRenderSetPictureClipRectangles(dmxScreen→beDisplay, pPictPriv→pict,0,0, &aRect,1);

• When trying to fix the bad fonts issue we…
  • cd /usr/share/fonts/X11
  • cp fontname fixed.pcf.gz (we chose something that seemed like a 'normal' font name)
