Vizard Changes

 

Changes (hacks) made by Chad Jones to the original Vizard:

Many of the python scripts required the newest version of python, which was not currently installed on the system. I compiled a local version for myself and used that when running he scripts. The directory was '/data/cjones/Python-2.3.4'. Once a current version is added to the systems, the scripts will be changed to that binary.

The Xdmx call in dmx/dmx.sh was slightly changed to reflect the fact that the user must use ssh to access the head machine. Input commands must be forwarded through ssh. herefore, the system gives the current session a DISPLAY variable, such as localhost:10.0, in order to relay I/O. The number after localhost increases depending on the number of onnections are made to that machine, so there is no one variable to use. I added 'setenv LOCALDISPLAY $DISPLAY' to my .cshrc so that the LOCALDISPLAY variable will old my 'localhost:#' on connect. The -input parameter to Xdmx was changed to '-input $LOCALDISPLAY'

dmx/hardware.cfg was changed to reflect the boba machines.

To scripts/kill_chromium.py: added line 'os.system('killall -9 ' + conf)' in order to help clean up applications that failed to close.

To vizard.py: In start_wall() function, removed the start_wall.py because X servers are already running on boba machines and cannot be changed. start_wall() just executes /usr/local/bin/vidwal' now.

Possibly some minor changes elsewhere.
