Hi Barry, I can confirm your description and I don't think you've got "busted hardware" as my Nexus 7 (2012) works fine with Android but shows the same problems (flickering display, blank screens, complete unresponsiveness) with the present saucy version of Ubuntu touch. I haven't tried the above mentioned surfaceflinger workaround yet, will be trying at the weekend.
