Just add a comment here that I have a new fast PC + SSD + HD4000 graphics and I get both these problems on frequently updated Ubuntu 12.10. I "solved" the low graphics mode issue long ago by changing from lightdm to gdm. I have 2 screens and occasionally I boot up and get 1 black screen but I have found this corrects if I switch to a console terminal (i.e. ctrl+alt+f1) and then switch back to X (i.e. ctrl+alt+f7). Both these problems occur with or without xorg edgers ppa (which upgrades kernel to 3.7.0 currently). In fact I tried that ppa again today and still got a black screen.
