The sleep problem on some Latitudes is caused by a bad BIOS/EC. (According to Linux ALPS developers)

 

R6RC2:

- Ignore invalid packets (instead of buffering). FIXED SLEEP ON V7 LATITUDE CONFIRMED BY "bigahega".

 

(It should fix sleep on V8, V3 Rushmore as well.)

 

Known issues:

- V7 and V8 tracksticks disabled. (till someone fixes it or helps me fix it)

- V6 not supported.

- As usual, most settings in prefpane won't work. They're not made for ALPS.

Sleep is almost fixed but, for example, for each 3 sleep/wake, there's 1 KP.

Overall performance, excellent.

Thanks Dr. Hurt!

Tested on Alps V7 for E5550 OS X 10.11:

 

No trackpad response, no trackpoint response, no keyboard response except for a few Fn key combinations like brightness.

 

After going into and resuming from sleep:

 

Full keyboard functionality returns, still no trackpad or trackpoint response.

Same issue for me in the latest beta. 

Tested latest 3 betas on Sierra, but still the same issue. After sleep, KP or keyboard/trackpad not working.

Kudos Dr. Hurt for this version! It is progress for me. Right edge works ok but bottom was still dead. I set

FingerZ = 1

SwipeDeltaX/Y = 400

and it is perfect for me.

 

E7440 Rushmore V3

Gestures work, trackpad works all around, 2-finger scroll is perfect, trackstick works with scrolling. After editing above lines it is final version for me. 

If someone wants, feel free to  check it out.

 

Thank you Dr. Hurt, now I can update to Sierra. This one thing was holding me back.

Your version is working almost perfect. 

Just a little detail: Why inertia isn't working on trackpad? I feel scrolling like old versions (without inertia).

Dr.hurt,

 

- try setting v/hscrolldivisor to 1

 

worked for me. No cursor is super smooth and gestures work great both 3 and 4 fingers. For E7440 users - give it a try if You have issues with Release 4.

Thx a lot Dr hurt, you are the best!

 

Modified kext:

Release 4 by Kfiatos.zip

Wow. This one is perfectly working on Latitude 6430u! 

Thanks so much bro!!

Tested Release 4 RC3.zip and Release 4 RC4.zip and both are working well with trackstick and keyboard, but with the trackpad i'm experiencing a strange issue: it moves very slow and stops working for a few seconds while tracking.

What should I do?

Tested almost all versions, but just works the keyboard, but neither trackstick and trackpad aren't detected on Latitude 6430u.

ALPS Device with ID E7=0x73 0x03 0x0a, EC=0x88 0x08 0x22

Hope you could fix this issue...

Cheers!
