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

Comment 1 Peter Hutterer 2017-11-06 05:50:46 UTC
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.

Comment 2 lejeczek 2017-11-08 22:36:28 UTC
could it kernel driver?
My other laptop HP Elitebook 745 g3 this problem does not exists, and fedora would be virtually identical on both.

Comment 3 Peter Hutterer 2017-11-14 05:35:44 UTC
dell and HP have different trackpoint hardware so yes, hardware is a factor here.
