Comment 79 for bug 1700657

Was trying to troubleshoot this after I got my 720 yesterday day and this thread was a godsend, I downloaded the latest stable kernel, applied the line patch and it worked perfectly. Thanks!! :D

But I think one issue that I am running into is what others mentioned above, I have to power cycle/reboot one or more times to get the machine to boot into Ubuntu, otherwise I just get a black screen and it hangs. I think it was mentioned above that it was a problem with GRUB mostly, is there an easy way to fix that ?
