How can I make wavelet/lambert work with the Lyon Lamb?

Wavelet and lambert are permanently hooked up to the Lyon Lamb. (Their video is automatically split to go to three places: their monitors, the Lyon Lamb, and the workbench projector.) There are two new switches just to the right of the big monitor. The top one controls whether wavelet or lambert's video gets sent to the Lyon Lamb, the bottom one controls the input to the workbench. Wavelet note: Wavelet needs to be in "normal" video mode, not the stereo mode it's usually in for the workbench. (Even though the picture in stereo mode looks fine on the monitor, the colors are much darker when the output is run through the Lyon Lamb.) As root, run

 /usr/local/bin/regfx normal 
Note that this restarts the graphics pipeline, and thus logs you out and makes the monitor go black for about 10 seconds. When you log back in, the screen will be at normal size. When you're done with the Lyon Lamb, you can put wavelet back into workbench mode by typing
 /usr/local/bin/regfx workbench
(See the
video troubleshooting page for a few more details.)

Lambert note: If you will be running an extended session off lambert you may want to swap cables so that the monitor, keyboard, and mouse in the video room are connected to lambert instead of wavelet. The easiest way to do so is by swapping cables in the machine room (RGB, sync, mouse, keyboard). Please put them back in the default configuration when you're done.


Why do my colors look weird on the Lyon Lamb?

There are small switches underneath the RGB inputs on the back of the Lyon Lamb. These should all be set to the "75 Ohm" position. Setting them to "off" "terminates" the signal, which has the side effect of amplifying the signal. If your colors look weird, one or more of these switches probably has been accidentally moved to the "off" position.
