[X1C6] Thumb/Joint is not detected properly -> Click+drag not working #173

I made some more observations: In Windows 10 the touchpad isn't recognizing touch input by the joint/thumb aswell. BUT: When clicking with the thumb it is recognized properly and highlighting of text and drag and drop is working fine. Could it be that this is because the trackpad is the NFC version? I disconnected the NFC module from the touchpad but drag and drop is still not working/the same behaviour. When disconnecting the NFC module the trackpad isn't recognized as trackpad in the macOS preferences anymore - only Mouse settings are avialable which are there for the Trackpoint if I remember right? Perhaps all of this is because of the NFC version of the touchpad? I can not imagine that all X1 Carbon users accept this horrible behaviour. :/ Disabling the NFC module in BIOS or removing the whole module doesn't work either. I think this trackpad with the NFC interface is kinda different to the already working once... Also there is a I2C interface AND a syn smbus traceable in windows device manager. |

This is mostly going to be a software issue (in VoodooRMI). VoodooRMI rejects touches which are too tall/wide and doesn't revalidate them if you click with the touchpad. I believe there is some configuration you can change in the #readme which should help. I'm busy for the next few days but I'll see when I can take a look at this. |

I already tried several settings but it doesnt work. It's kind of funny because it only happens when highlightning text and dragging folders. When moving windows around this behaviour doesnt happen.. Can I share more information which could help in this case? |

Pressing/clicking three times in the down-middle of the touchpad with my thumb this is what the log shows: When pressing/clicking (round about 5 times) with my forefinger in the down-middle it logs: Trying to drag and drop a file and loose it "in between" looks like this in the logs (Remarks: There is no button down in the logs): When moving a window, which is working as expected, logs look like this. Remarks: It is recognized that the button is down: |

Here is my config, perhaps it helps aswell. All together, the trackpad comparing to the T480s which is sitting next to my x1 carbon 6th works very bad (e.g. double tap with two fingers isn't recognized properly). I'm at some point where I'm willing to change the trackpad to the non-nfc version and hope this one works better... But perhaps the logs and my configuration will show the problem, I dont understand it :( |

Another investigation is, when I'm using my thumb to move the crusor this is what the logs tell me. It looks like there is a conflict as soon at the thumb is detected? |

Describe the bug
Thumb/Joint is not recognized which makes it impossible to click and drag thinks or highlight things.
To Reproduce
Download FingerMgmt and try to use the joint of the thumb as input.
Expected behavior
Click and thumb/joint is detected properly so Click+drag and highlightning of text is possible.
Video
Tried to sho the behavior on the X1C6 in a video: https://youtu.be/hufQXLozEl8
On a T480S it looks like this: https://youtube.com/shorts/ZnPeELd4C1g
