DisplayLink Green Screen, but no WM loads on that screen

[maldridge]

I have a sheevaplug with debian 6 on it, this is a fresh install unpacked from a backup I made so I could experiment with different applications on the plug, so there is nothing but the base system on it.  When I plug in the displaylink monitor, it goes green and dmesg shows that it is detected.  The model, resolution, and /dev alias are all correct.  However, typing 'sudo startx' causes the screen to blank momentarily, then return to green.  it does not load LXDE (which I have installed after decompressing the clean image).  I know this has to be something simple, but I can't find it.

Any help is appreciated.

nevermind, solved my own problem; it turned out to be that I had installed in the wrong order and so overwrote newer files with older ones.  if anyone needs/wants my  working system, I made an image of clean debian with lxde for sheevaplug, I'll upload it upon request
