Description of problem: hi my Dell Latitude e7470 has extremely sensitive track-stick in gnome@wayland, pointer with the slightest touch goes across the screen with lighting speed. I have tried different values for: Device Accel Profile (242): 2 Device Accel Constant Deceleration (243): 10.000000 Device Accel Adaptive Deceleration (244): 10.000000 Device Accel Velocity Scaling (245): 0.100000 but changing these values has no effect on pointer/stick sensitivity. I think something changed recently, maybe with kernel 4.13.9.xx I've tried different values for id=6 & id=7. $ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ xwayland-pointer:13 id=6 [slave pointer (2)] ⎜ ↳ xwayland-relative-pointer:13 id=7 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ xwayland-keyboard:13 id=8 [slave keyboard (3)] Version-Release number of selected component (if applicable): libinput-1.9.0-1.fc26.x86_64 4.13.10-200.fc26.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
These values are ignored by libinput, so changing them doesn't do anything. Looks like a duplicate of bug 1509017, please have a look at that bug, thanks. It's f27 but the libinput version is the same. *** This bug has been marked as a duplicate of bug 1509017 ***
could it kernel driver? My other laptop HP Elitebook 745 g3 this problem does not exists, and fedora would be virtually identical on both.
dell and HP have different trackpoint hardware so yes, hardware is a factor here.
