G'day Debian community. My winter-hobby to migrate my whole infrastructure away from Windows suddenly came to an hard stop.
I can not get the touchpad to work in my two Lenovo Ideapad 3 Flex notebooks (Type 11ADA05).
The machines worked under Win11 so far – where every hardware component was working. Now after a fresh install of debian Trixie with KDE Plasma desktop, everything seems to work exept the Touchpad. The Multitouch-Screen, Keyboard, Special-Keys etc. are working out of the Box.
The boot log show the following entries, that -to my understanding- are hinting in a certain direction.
Seems the touchpad is not identified as an known I²C device. Which then prevents that the drivermodules are installing the correct device-drivers (unloading, and reloading i²C related modules changes nothing).
I also followed an other hint (also from the logs and from Ubuntu/Debian releated forums) to boot with parameter set. That did not change anything funcionally.
Here is the output fromI have no clue, how to tackle down this issue any further. Thankful for any hint on how to get on!
