I have follow the instructions listed in the forum as well as the thinkorswim website. I can get all the way to the launch point for showing the desktop and it won't show I just get a black screen and it freezes on showing desktop. I think it has to do with one either the java I am running or so have said I need to get the thinkorswim tech support to disable the splash start up screen.

, Java and Xorg used up all CPU.
I managed to properly run Thinkorswim after switching to Openbox as a window manager. My guess is that any non-compositing window manager will do.
