Hi, after update from 3.18.7 to 3.19.x my Logitech touchpad became almost unusable. I use OpenSUSE Thumbleweed and tried both custom and vanilla kernels. AFAIK, the problem may come with this changes: http://lkml.iu.edu/hypermail/linux/kernel/1412.1/03246.html
The symptoms are as follows. 1. The touch density is twice reduced: I have to make longer finger motion for a smaller pointer movement. Possibly, it's because the KDE starts to detect the touchpad as touchpad - and not the mouse as it was before - and applies some preferences like the pointer acceleration, etc. 2. Some gestures stopped to work: 3-finger swipe up, down, left, right - so, there are no more "history back-forward", "SuperKey", and "SuperKey + d". 3. Multi-finger tap detection is awful: it doesn't detect 3-finger tap in 50%, it sometimes detects 2-finger tap instead of click+drag, or when the second finger is slightly touching the surface. Can anyone make a suggestion what should I do, but to stay on an older kernel version? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
