Dedoimedo posted a negative review of Ubuntu 12.10 Quantal Quetzal 64-bit on a high-end laptop with an Nvidia graphics card

Depending on your understanding of the time-space continuum, several days or several minutes ago, I reviewed Ubuntu 12.10 Quantal Quetzal on my SSD-ed laptop. For the lack of a better word, the distro sucked. There were too many issues, and it's hardly the worthy successor to Pangolin. The only question remaining is, can it redeem itself on some proper high-end hardware, not that a dual-core, 2GB, Intel graphics, SSD laptop is a weakling either.

I will not repeat most of what you've already seen in the first piece. I mean, multimedia, printing, all that, fairly trivial. What I will be focusing is the graphics stack, which is where things get really interesting. If you have an expensive Nvidia card in your Linux box, then you might want to pay attention in the coming minutes, as this article might be seriously worth your time, money and mental health.
