Linux/DLPDLCR2000EVM: Can't output the Desktop

Tool/software: Linux

Hi,

I run DLPDLCR2000 on Beaglebone Black with the latest Debian. And I installed the dlp_lightcrafter-1.0.19 driver successfully, also I use python scripts like LEDTest.py and orthers scripts to test the projectors, it can show pictures well.

However, it can't output the Desktop.

First,I entered "export DISPLAY=:0", but not worked. Then, I entered "i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i" and "i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x1b i", not worked too. Still Splash picture.

So, how can I output the Desktop, and use MplayerTest.py? (I've installed Mplayer)

By the way, how to display a picture, and  use C/C++ to display picture after processsing?

Thanks.
