I have a newest generation hp dm4 (the trackpad and mouse buttons are separate, unlike in the previous generation). The trackpad works fine in windows, but in Ubuntu the mouse is erratic and non responsive. By going up and down on the trackpad, I can sort of get the cursor to go left and right, and thats it. I think there is some software or driver problem, but that is the extent of my knowledge. I hope someone can help.

Re: Problem with touchpad brand new Pavilion dm4-2015dx Options 07-15-2011 11:22 PM SOLVED!! Here's what you do. Reboot. Login. Go to Device manager and roll back the mouse driver to PS/2. the problem is with the ALPS Driver. You will loose some functionality (just bells and whistles) but the touchpad and mouse will work without freezing up. (You don't have to screw with the bios or any of that rubbish). Enjoy your new laptop folks! | |||
