Hi Bernie,
Thanks for your prompt reply! Here is the back story…
I am using a Henge Dock for my Macbook. I did do some hand configuration and had everything working with 2 monitors (one using mini-DVI, the other USB Plugable). I usually boot into Mac OS X, and it works great! I sometimes get a fuzzy monitor (either one), but after a several seconds that clears up. Also, for the record Windows 7 works every time. (Though I am not a real fan of Windows, much more an OS X, linux guy.)
The problems started when I ran the Macbook as an Ubuntu laptop, lid open, with the mini-DVI attached to my HD TV (for Boxee). I wasn’t thinking, and I used the NVidia configurator, without properly backing up my existing configuration!!!
The configurator added some typo errors to the xorg.conf, (I selected merge, rather than write a new one). I did a rescue boot, so I could see the errors on startx, I removed the errors, and got it partially working.
By the way, I do see the DisplayLink taking over the console (after boot). I do not see the GRUB prompt, before that. Just this afternoon, I did get it to boot into a Green screen (is that a good sign?).
Anyway, now I figure the best solution for Ubuntu, is to not use the USB monitor for now. And wait for another DisplayLink driver update. I do not use Ubuntu on this laptop that often, and I do expect to use Ubuntu in true laptop mode.
I will try your suggestions and see if I can get it working with the mini-DVI monitor in the Henge Dock.
Thank you for an excellent product! I am very happy with it’s performance with the 2 main stream operating systems. Hopefully a later DisplayLink driver will improve the Linux, but it may also be due to an interaction with the NVidia driver.
Thanks again,
Craig
Ps. I will post again, once I get things sorted out.

Ok, I made your suggested change in modprobe.d, then re-configured using the NVidia configuration tool. I added another Gnome Panel, to the 2nd screen and dup’d the needed items.

Ooops, forgot to run the 2nd command you suggested! Going to try again. I guess I was tired last night
Thanks for your help!
