[Q] debian, webtopMOD and post #865 - Atrix 4G Q&A, Help & Troubleshooting

Re: [MOD] Full Linux (Debian) inside WebTop! v0.2.7
I managed to unlock, root and install WebTopMOD on my new2me searet Atrix 4g. Great feeling for an android n00b! I can run iceweasel, gimp and whatever I like just like any linux distro on the webtop as long as I start a new shell to launch linux apps. I had wanted to continue on to using the instructions in post #865 by jissee44 to get the xfce4 window manager running. No luck! I can launch (I think) xfce4 manually and the entire view changes - new wallpaper, new toolbar, but no access to the linux filesystem - everything connects to the android filesystem.
Here is what I think is needed to see what went wrong. There are only two files to edit when following post #865. I am including the entire file as the posting I was following does not include diffs.

Can someone give me some clues as to what has gone wrong? I'm not sure if something is missing or if I broke something in my edits, and there are no follow up questions on the post. There are 13 thanks.

making progress?
Okay, I'm just hearing the crickets.
> startxfce4
provides some of the results I want, but leaves AWN in control. Now that the new ICS ROMs are coming out I'll have to see if I can just make webtopMOD usable until something better comes along. It would be good to see better documentation for n00bs. The forums are a little rambling. There is a lot of good info, its just scattered.

Hi,

The Debian is a Chroot

Thanks for the terse explanation, jisse44. It took me a while to get around to reading the docs on chroot. It makes sense that webtop isrunning in a sandbox. That is inherently limiting.
I still love webtop and my lapdock. It will be interesting to see what happens with webtop and the ICS ROMs on the Atrix 4G.

Or not....
By now you can only run last new "webtop" on ICS Roms, and this is not THE webtop, it's a tablet mode: no Ubuntu or debian, only Android....
