You Can Keep Your Windows 10
Well, my return to Windows (10) ended up being fairly short. I have an almost 5-year-old Samsung laptop with an AMD chipset. It originally had Windows 7 and a year or so after I got it, I started slapping various Linux distros on it and have basically done that ever since, with a couple of brief returns to Windows (8) and most recently Windows 10.
I wanted to see how Windows 10 had evolved during the past year, and put it on before the free upgrade ran out. It worked fine, with the exception of some quirky touch pad behavior, which I could never quite configure to my liking - it seemed very "jumpy", and no amount of tweaking seemed to fix it.
I then rashly decided to plop the newly-arrived Anniversary Update on the laptop, and ended up with several seeming random and arbitrary UI changes, and a freezing problem. My laptop would do solid lock up on average once per day following the upgrade. I checked my RAM and verified the laptop was not overheating. The touch pad was also still acting nervously.
As I did not really *need* Windows 10 for anything specific, I eventually got tired of making accommodations and just went back to Linux; this time, Linux Mint 18 Cinnamon edition.
Interestingly, this time my Linux install was not all sweetness and light, it was quite dark. It came in the form of a black screen with a movable mouse pointer after I logged in (just before the Desktop should start up). The fix ended up being easy enough after some Googling, and I have had no more issues in the several days since (and no system lock ups either, I should point out).
In my case, I was able to use CTRL-ALT-F2 to get to a terminal, then login and run the following, then reboot.
sudo aptitude install xserver-xorg-video-radeon
