Related to the above post, I am also facing the same problem on E5450 with beta 3, after sleep the touchpad does not work moreover interacting with keyboard after a few keystrokes hangs the system and it gets restarted.

Test Results using the Latest Release 6 beta 3 (on 10.11 El Capitan):

 

ALPS: Found a V7 TouchPad with ID: E7=0x73 0x03 0x0a, EC=0x88 0xba 0x2a

 

Touchpad (all trackpad gesture settings are checked):

- two finger scrolling works, but is way too sensitive (even with scrolling speed at minimum)

- two finger right-click is rarely detected, usually causes scroll

- three finger up/down is recognized

- three finger left/right NOT recognized

- three finger tap recognized as middle-button mouse click

- four finger pinch/zoom NOT recognized

 

Trackstick (with mouse speed set to minimum):

- pushing up - cursor moves down slowly

- pushing down - cursor moves down very quickly

- pushing left - cursor moves right very quickly

- pushing right - cursor moves right slowly

- any movement also causes a right-click press and hold and requires multiple clicks from the touchpad to return to the unclicked state

 

Also I am having the issue others have reported, after waking from sleep there is no touchpad response, and system freezes after a minute of keyboard usage

Hello Dr Hurt, thanks for your amazing work.

In the last version (v6) my trackpad doesn't work anymore, while with v8 beta 5 it works very well.

Using last version of Sierra.

Hello,

 

i have an Lenovo Y50-70 with ALPS trackpad. Where can i check which version i have?

 

I think i have an ALPS trackpad because the installed windows drivers are from ALPS.

 

Thanks

Release 6 beta 4:

- Start touchpad before keyboard. (sleep problem fix?)

- Increase pointer resolution (smoother movement). (worth it?)

- Add V5 enable. Probably still won't work.

- Re-enable LTO since it didn't seem to break anything. 

- Removed all Synaptics, Sentelic, Generic Mouse code. (smaller, cleaner and faster driver).

 

PS. I'm quite busy those days so I'll not be replying or updating/fixing anything for some time.

Install the driver, reboot and check the log (type "sudo dmesg") in terminal.

This works for my V5, its more responsive now in some things like scroll and gestures, i will test sleep (i had sleep problem, when wake from lid closed, problems fixed editing DSDT, i think related to USB in Sierra).

BTW scroll left to right works better in previous version like v5, now lanchpad when i scroll stuck at mid. Thanks for your work as always
