New TouchPad driver for E6520 / ALPS

[bpedman]

 

Hi,

 

can´t get my touchpad working with 1.8.4

Keyboard is working fine, any idea someone ?

Laptop is a Dell Latitude E5520

May 31 11:11:54 localhost kernel[0]: ApplePS2ALPSGlidePoint::probe entered...
May 31 11:11:54 localhost kernel[0]: ApplePS2Controller: Timed out on mouse input stream.
May 31 11:11:55 localhost kernel[0]: ApplePS2ALPSGlidePoint::probe leaving.

 

This is not good. The touchpad isn't responding to a probe...

 

The versioning is a little weird right now...all the drivers I have posted will output 1.8.4 right now in the log. Do you know which version you downloaded from my first post? v2, v3 or v4?

That's a very good question.

I will try v4 again cause the e5520 has a multi touch touch pad, i will report back.

Ok V4 works now, thank you for the hint!

2 Finger scrolling is working too! i´m happy ;')

[bpedman]

OK, I removed the older downloads just to avoid confusion in the future...just kept them there for history but really anyone should always just use the latest version

That's great. Could you look at /var/log/system.log and look for a line that says: "Found ALPS Device with ID....." and paste that here. I would like to keep track of models that are working and have been tested.

 

Also, glad you have 2-finger scroll working. Is it working very well? On mine it works but it is not very smooth...I need to make some tweaks there I think, but if it works well for you then maybe I shouldn't touch it

I will look @ it tomorrow it's gmt+1 here so nearly 10pm

Hello,

 

I am new here. I have an old kext installed that lets me use my trackpad as a standard mouse very smoothly. When I installed your's it wasn't nearly as smooth, I lost the click and drag abilities and I was able to see all the trackpad options. Sadly, clicking and un-clicking options didn't affect my trackpad at all.  I still didn't have multitouch support.

 

I'd really appreciate some help! [:

 

These are my working kexts with no multitouch support.

Could you look at /var/log/system.log and look for a line that says: "Found ALPS Device with ID....." and paste that here. I would like to know what the model is. It sounds somewhat similar to what driedger reported here https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/page-2&do=findComment&comment=19378. Need to know what model it is so I know where to make any changes.

I will if I'm @ home again.

Tapatalk is noticing me...

Thanks Bpedman for your work on a kext for alps trackpads! Been waiting for over a year for someone who could modify the voodooPS2controller. Would have liked doing it myself, just didn't know how to Thanks!

 

I'm on a Dell Insiron N5050 with 0x73 0x02 0x64 Alps trackpad, Looks to me the same hardware as your E6520 has. I'v loaded both the V4 version and the V4-1 version you posted on the 29th of may (both Debug versions). Both gave me the same result: Trackpad is working, but no scrolling, single or multi touch.

 

As instructed I removed any old voodoo kext an other ps2 related kexts. Installed the prefpane to /System/Library/PreferencePanes and copied the VoodooPS2Daemon to /usr/bin with RehabMan's org.rehabman.voodoo.driver.Daemon.plist to /Library/LaunchDaemons (what does this Daemon do? and how can i check if it works correctly?)

 

Here's my System.log output Hopefully someone can help me figure out what's going wrong. 

Seems to me the problem has to do with these log entries. It probably souldn't say ERROR   and "Device initialization failed. Touchpad probably won't work" doesn't seem promising either...

A while back I opened my N5050 to clean out dust and made a picture of my ALPS touchpad, not sure if this is of any use here, but here's a picture anyway.

 

 

Hope someone can point me in a direction on getting scrolling (single or multi touch) working on my n5050. Any help would be greatly appreciated!
