I wanted to disable the pointer stick on my Dell Latitude E6420. After searching for it online, I found out I had to install Dell's trackpad driver, so I did. After that however, it completely disabled my trackpad AND pointer stick, even though it said both were enabled in the settings. Now I am using an external USB mouse as my internal ones no longer work. I tried uninstalling, and was met with a BSOD after reboot, and had to go into safe mode and have it reinstall the driver automatically. It STILL didn't work, and now I am stuck without a trackpad, even after trying to reinstall it. Please help!
