Let me start off by saying I have tried several fresh installs of 13.04 and each time the mouse and keyboard can not function properly. I'm able to move the mouse but can not click anything; as for the keyboard I'm unable to launch anything either. I then decided to reinstall 12.10 and everything worked fine so I upgraded to 13.04 which then yields the same issue, unable to click and use keyboard. Not sure what to do here, do you have any ideas?
Fixed it. Turns out it was a driver issue for graphics. Logged into safe boot, Installed nvidia drivers and everything works just fine.
