Can't use mouse and screen res changed after updating kernel?

view full story

http://askubuntu.com – In an effort to fix problems which I was having with 12.04 on the stock kernel, I had updated to v3.5.1-quantal successfully in terminal from the following official website: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Upon reboot, the position/resolution of the screen was changed, and my mouse no longer works. I had to hard reset and hold down shift to access the previous kernel, could someone kindly tell me how to fix these issues with the new kernel so I can start using it? If it is relevant, I have no discrete GPU and am using an intel i5 3570k with the integrated graphics. Thanks. (HowTos)
