Urgh. No cool icon in the right top corner. I see the advanced backlight control icon, the display icon, the audio, the connection icon, and the battery icon. Looks like I missed a step somewhere, but in that last set of commands in xterm, I followed every step and each time it worked. I was hopeful! Darn it. I did reboot, which to me meant just manually shutting down the device by pressing the on/off button.

I'll go back through that last set of commands again later today, but I was pretty confident we hit all the steps, and that each one took.
