Two-Finger Scrolling for Inspiron 1520/1720 1.0

Sign in to follow this  

About This File

I took a VoodooPS2Controller.kext modified by Andy Vandijck and an ApplePS2Controller.kext modified by Slice and combined them to make two-finger scrolling a reality on the Inspiron 1520/1720. Install to S/L/E along with the AppleACPIPS2nub.kext. Use the Apple Trackpad prefpane attached to adjust the settings. Install to /

System/Library/PreferencePanes.

EDIT: I updated the ApplePS2Controller.kext to include an ApplePS2Keyboard.kext that runs in 64-bit mode. The previous version of the keyboard plugin only ran in 32-bit mode.

EDIT: I successfully got this to run in Lion DP4 on my Dell Inspiron 1720.

EDIT: It does not appear that the prefpane works in Lion. I'll see if I can find one that will.

Works on a Dell Studio 1558, but the moment you touch a key on the keyboard it'll just stop the mouse and keyboard working.

I think the attraction of these kexts is that they give full two-finger scrolling function to an Alps Glidepad. If you don't have an Alps trackpad (such as a Synaptics trackpad,) there are probably already better solutions out there.

can you help a newby with a sony vaio figure out how to install those downloads?

I downloaded them, and none of them are files I can just click on and have something run.

nor are any of the file something I can open and read on how to install them manually.

@jamiefettig - install the two kexts to /System/Library/Extensions using either kext utility or kext wizard. There are no self-installing drivers in OS X. Be sure that you repair your permissions before you reboot. Kext utility will do it automatically for you. Kext wizard requires you to select that as an install option. For the pref pane, just double-click on it, it will ask you if you want to install it, select install for all users, enter your admin password and it will install in the proper place. There are way better tutorials than this on how to install OS X drivers. Try looking for one using Google. Good luck.

Thanks very much, This sorted out the trackpad on my alienware M9700i - now everything works perfectly after changing the wifi card.

Thanks again.

Cool man, it works great on the lenovo laptop in the 10.6.8, it seems can't load the voodoops2controller after upgrade. But this one is cool.

Hi, I just found that the function of CTRL+F12 key doesn't work, with the previous driver it can bring the menu of "Restart Sleep Cancel Shut down", even though it haven't a big shortage but if it can be implemented, that will be nice.Regards!

trakcpad.prefpane does not work for me. I neglected to keep copy of original also. "Could not load Trackpad preference pane." is the error I receive.

In Asus K50INSeries MCP 79:

the Lion

The keyboard works.

but not from the Trackpad.prefPane to install.

Says that the settings are installed with the Os X and can not be modified.

Is there a solution?

works fantastic on inspiron 1525, though installing the prefPane can be a bit tricky if the file already exists in S/L/PP

always remember to check E/E for VoodooPS2Controller.kext, it will conflict with this kext causing kernel panic
