I was about to file a bug report but I’m actually not sure this is a bug…
I have a Logitech K400+ bluetooth keyboard with a small touchpad on it. I noticed it behaves as if all its inputs were converted to mouse inputs, unlike the laptop’s touchpad:
- 3+ fingers gestures don’t work
- 2-finger scroll goes through 3-lines by 3-lines, instead of continuously
- pinch-to-zoom behaves like ctrl+scroll, using the browser’s zoom (showing in firefox’s nav bar, that goes in increments of 10%) instead of the smoother zoom of the laptop’s touchpad
So I went to the system settings under Mouse & Touchpad. The Mouse settings have a dropdown to select the mouse that you want to adjust the settings of, but the Touchpad settings don’t. My K400+ touchpad appears in the Mouse settings dropdown, which confirms it is identified as a mouse.
So now I’m wondering if this is a problem with the K400+ touchpad, with mine in particular, or with KDE (maybe having more than one touchpad is not supported ?).
