See OSCC MAMPU website for the details.
Apart from presenting a paper on Building OSS Competency, I am mainly taking care of the AV. I'd like to point out an instance where the overhead projector could only flicker the Linux screen intermittent. The video projector model was Sanyo XtraX and was mounted on the ceiling as shown below.
After changing over 2 different VGA cables and checking the connections, nothing improved. Some put it to the Linux being the problem, as other functions were said to have ran smoothly. The AV man finally came and brought a VGA switch with built-in booster, this managed to put the display on the large screen. When another two more projectors were used with a splitter, there were lines scrolling vertically. This was for the projector screens at the sides. This showed that there is not enough power supplied to the projectors.
