Comment 92 for bug 565543

Same issue here. I have a Sony Vaio VPCEB3C5E, touchpad is recognized as a PS/2 mouse.

Basic movement and vertical scrolling work, but nothing else. The behavior of the trackpad is erratic, sometimes it becomes very difficult to control it (or becomes completely wild).

I should also point out that I had major problems with the trackpad during installation. The trackpad wouldn't be recognized at all. I had to add the boot option i8042.nopnp in order to be able to use the trackpad at all.

Any status update about this bug would be very much appreciated.

 Thanks
