Kubuntu is almost like Ubuntu, and then not at all. It is amazing how much difference there can be between two operating system releasing sharing so much DNA. As you probably recall, I was utterly disappointed with Quetzal, on two occasions. The first time, on a generic laptop with SSD and Intel graphics, where it blossomed with bugs and glitches. And then, the second time around, when it utterly failed me on my high-end laptop with its Nvidia card.
For this very reason, I will be testing Kubuntu 12.10 Quantal Quetzal on the said laptop first, to see whether the Nvidia issues are strictly related to Ubuntu and its unity desktop and who knows what else, or perhaps a much bigger, more serious phenomenon. So we will begin with a dandy setup, 4GB RAM, Nvidia GT 320M 1GB VRAM card, with two operating systems installed on the internal disk, and booting a handsome new bunch from an external USB disk. Sounds glorious, and as real as it gets.
