Personally I would remove everything after the 'ro' and only try the 'nomodeset quiet' first. (after the 'ro' means leave the 'ro' there!) Then experiment from there. I've never seen so many entries before. The bit with the radeon and the nouveau are not necessary as far as I know, especially with you having the Intel 4000 graphics chip set. I feel your pain however, I have the "Sandybridge" chipset with nvidia's terrible "Optimus" hybrid setup. (intel/nvidia combo card sharing a GPU) It was a giant pain to figure out. You might also want to try to play around with your xorg.conf file. Another idea would be to drop to tty1 and sudo su, run smxi and let it re-install you intel graphics. That worked in the past for me when I hosed my system trying a beta driver from nvidia.
Will try that, but for the lightdm issue I`ve found this bug, and I guess it`s what causes some of my issues. They post 3 workarounds that I`m going to try...
