WOW, did anyone ever tell you that your a cool guy? Yep its true its official, you win a cookie. lol
OK, now onto more important matters, Linux distrobutions! I know what you are going through, as my notebook has a two GPU setup, the crappy Intel, and the performance Nvidia. So many Linux distrobutions do not do well with proprietary Nvidia drivers, due to lack of proper support through the OS kernal being used.
I expressed on more then one occasion to Jacque that I was concerned about Nvidia driver support in his next OS. I believe he understands the importance of a fully functioning Nvidia driver that activates the GPU for full performance. But here's the thing, if he's doing that, then he's going to want to make sure those with ATI, will also function well, cause people have either or right.
Here's what I think, if you like Zorin OS 12 Ultimate, and the OS is working for you, you should stick with it, especially since you paid for it. However, if your like me and the OS has puked all over the place, then I would suggest moving over to Makulu. Truth is, its in BETA right now for version 12, but were hoping to see a full release soon. But you can try the BETA 1.42 version running in live mode if you wish, just remember its not a full release so don't expect perfection.
But I can tell you what you can expect, the ability to change to any windows theme you like, weather its classic, XP, 7, 8, or 10. It uses XFCE desktop which is highly customisable. The last release is based off of cinnamon, but the new release will be based off of Debian. Jacque is making that change due to compatibility with hardware. Which really is getting me excited about it, because it might mean that the OS will be able to communicate well with my Nvidia GPU without puking all over the place.
