Sorry for taking so long to respond. I’ve been working 12 hour shifts in a food factory and I’ve been so tired I’ve only had limited time to dedicate to sitting down and working on this and the suggestions given(sad excuse, I know, but I’d rather not mess things up further working tired).
I ultimately decided that since most of the problems people were having kept referring to using a VM as the host, etc, or in the one case, somebody with the dvi to hdmi adapter which didn’t apply to me, that I should actually install 14.04 on my host hdd.
I was attempting to use a large live thumb drive(116GB(sandisk 128GB 3.0 but in 2.0 usb ports(all ports on my hosts have only been 2.0 oldees)) in my previous flash attempts due to not wanting to change my OS(had things set up ideally on my last OS but after having some config issues arise anyway decided to flush and fresh install) and that finally worked and everything flashed as simply as it should have.
Sometimes it’s the simplest things that you just don’t think would make a difference. I tried from live usb with a persistence of 60GB on both an older dell inspiron laptop and a slim tower gateway with no luck. All times had both host and TX2 connected to my router via Ethernet cord(not wireless). It never went much further than acquiring the IP after reboot and often didn’t acquire it although it did the first time. But with fresh full hard drive install, it worked perfectly. I watched the terminal carefully and when it said reboot/reset the TX2 I pressed the reset button…after about 20-30 seconds terminal showed it acquired IP and it actually went through installing everything without a hitch.
I’m typing this on the TX2 right now.
Hope this helps if the majority of these problems are arising from using live usb, usb 3.0 ports,DVI/HDMI adaptor ,WiFi or VM. I know sometimes, after going through 10 different versions of linux etc, finding what’s right for you, that when you get things set just right and may be utilizing all your hdd and in my case unable to resize, repartition it, that live or VM seems the way but just wipe your host system and install. It’ll save the headaches down the road. It also seems somewhat easier to setup dual boot from ubuntu as your primary install rather than the other way around IMO.
