I saw the change log form ubuntu4 and 5, and it definitely fixed an X configuration issue that caused problems specifying a specific XServer driver. I recommend you upgrade the ltsp-server. As I stated earlier, though, I think there may be a problem with video playback under LDM_DirectX=True mode, so this may not help entirely.
