An Ubuntu image for Dell Inspiron 3168-8773

So, thing is - it came with Windows 10 installed, and as a full time Linux user, you can guess the first thing I done.

Yet under Ubuntu 17.04, Ubuntu 16.04, Linux Mint 18.2 I consistently got strange error, when system freezes fully, not even leaving kernel panic or display manager fail logs. It was rather frustrating as you can imagine, and thus I tried to find official Ubuntu build for it, hoping to get some solutions to my problems for it (according to this, my model supposedly is tested for Ubuntu compatibility, and no major failures were found, but I think Canonical is not affiliated with Dell, and that argument has no power here)

Also Fn + Down/Up (PageUp/PageDown) combinations aren't working under those distributions as well.

And yes, I tried this Dell's pageto download Ubuntu from Dell, but it constantly redirects me back to Windows 10 image :(
