X230 Synaptics driver bug [pics]

#1 Post by Jake.Werecat » Sat Oct 17, 2020 7:58 am

I am a long windows 7 user, however lately after win 7 support ended I am considering a transition. Yesterday I have installed Win 10 on a spare SSD, just to see how it behaves and if I was ready for that.
Spooky thing happens with Synaptics touchpad driver.
On win 7 I, as probably every thinkpad user does, use middle click as a middle click - for opening in new tabs, closing tabs in browser etc. It of course works for scrolling as well when clicked on website background. So, I have the function set to neither. (Setting it to scorlling is stupid, as then you can't us it for anything else, whilst you can scroll anyway when "neither" is selected)

The situation is somewhat similar on Win 10. Scrolling for whatever reason is selected as default, but when I change it to "Use as a middle click" and use Apply or OK, and close the windows - nothing happens, the button is still in scrolling mode, opening the settings again reveals that radio button flipped itself back to scrolling. Issue is same no matter if I use mouse setting under "settings" or under "control panel"

Anyone ever encountered such a problem? Any suggestions how to fix it?

Same issue described here:
https://www.reddit.com/r/thinkpad/comme ... dle_click/
But without a solution.
And also here:
https://www.reddit.com/r/thinkpad/comme ... _a_middle/
but presented solution does not work. It does turn off that scrolling pointer, but the button does not function properly.

As far as I did the reseach, there ain't no elegant solution for this bug, as well as as there is no explanation about the reason. But theres is a workaround.
One need to change the following registry values:

Code: Select all

HKEY_USERS\S-1-5-21-2158515036-987303324-3988316896-1001\SOFTWARE\Synaptics\SynTPEnh\UltraNavPS2

TrackPointMode from 1214 -> 2214


HKEY_USERS\S-1-5-21-2158515036-987303324-3988316896-1001\SOFTWARE\Synaptics\SynTP\StickSMBTM2182

MiddleButtonAction from 0 -> 4

Some times the key can be called "stickPS2" instead of "StickSMBTM2182".
But regardless that, I gave up with Win 10. I guess I will keep Win 7 for the undefined future and meanwhile will work my way gradually towards linux.

Nice to know there is a workaround. Although you probably should use HKEY_CURRENT_USER and not some specific user in HKEY_USERS.

Good point, that would be more universal, and one could even make a clickable *.reg file for instant workaround injection.
