Chromebook with Ubuntu.....
Had a novel one in a couple weeks ago at the shop, the OS on the CB wasn't playing, neither was any of the hardware other than the screen booting and displaying a horrific mish-mash of corrupted GPU output. The reason:
Me: "Did this happen after a particular change in the system?"
Customer: "Yes, but nothing I'd done, nothing major, I just tried to install the latest Ubuntu...."
And that m'lud is when I hit him..... :insane:
