Hello,
I tried to improve the trackpad support for the MAcBook Pro 5,1 (late 2008). It does not seem to be possible to enable click and drag support with multiple fingers.
If you want to move a window or drag files you usually click and keep the button pressed with one finger while moving the mouse curser to the desired destination with another finger. Doing so with the button-less touchpad results in wrong behavior. The driver detects two fingers on the pad and interprets the movement as scrolling gesture.
I found a patch in a Ubuntu bug report. Based on that I compiled a custom kernel that does support click and drag. I wrote a small article about that:Custom Kernel for openSUSE 11.2 on MacBook Pro 5,1.
If it is interesting for someone please tell me. I will then make the kernel RPM available for download.
Bye,
miho
