Description of problem: After upgrading the kernel to 4.9.3 (from 4.8.16 - last update was performed on the 12th of january) today, the trackpoint speed of my dell precision 7510 is incredibly high (and therefor unusable). I tried to change the speed with xinput, but that does not have an effect. The speed of an USB mouse of the touchpad is ok. I even tried to set it up from scratch again on a new harddisk. Initially it is fine, but after doing an dnf update, I get the same result. That is what xinput tells me: xinput list-props "AlpsPS/2 ALPS DualPoint Stick" Device 'AlpsPS/2 ALPS DualPoint Stick': Device Enabled (141): 1 Coordinate Transformation Matrix (143): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Accel Speed (286): 0.000010 libinput Accel Speed Default (287): 0.000000 libinput Accel Profiles Available (301): 1, 1 libinput Accel Profile Enabled (302): 1, 0 libinput Accel Profile Enabled Default (303): 1, 0 libinput Natural Scrolling Enabled (288): 0 libinput Natural Scrolling Enabled Default (289): 0 libinput Send Events Modes Available (263): 1, 0 libinput Send Events Mode Enabled (264): 0, 0 libinput Send Events Mode Enabled Default (265): 0, 0 libinput Left Handed Enabled (290): 0 libinput Left Handed Enabled Default (291): 0 libinput Scroll Methods Available (292): 0, 0, 1 libinput Scroll Method Enabled (293): 0, 0, 1 libinput Scroll Method Enabled Default (294): 0, 0, 1 libinput Button Scrolling Button (304): 2 libinput Button Scrolling Button Default (305): 2 libinput Middle Emulation Enabled (295): 0 libinput Middle Emulation Enabled Default (296): 0 Device Node (266): "/dev/input/event5" Device Product ID (267): 2, 8 libinput Drag Lock Buttons (299): <no items> libinput Horizontal Scroll Enabled (300): 1 Version-Release number of selected component (if applicable): How reproducible: Set up FC25 on a Dell Precision 7510 and update to 4.9.3. Did that twice now. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
It looks like opensuse tumbleweed with 4.9.0 has the same problem. Maybe the bug was introduced in 4.9
Problem still exists in 4.9.5
