Description Luke Hutchison 2014-08-04 23:16:50 UTC
On a Dell XPS 15 Touch laptop with a hidpi display running Fedora 20, when I plug in a mouse with device id 045e:0039, "Microsoft Corp. IntelliMouse Optical", the mouse pointer barely moves when the mouse is moved.

The default velocity and acceleration settings when the mouse is plugged in are:

	Device Accel Constant Deceleration (263):	1000.000000
	Device Accel Adaptive Deceleration (264):	1.000000
	Device Accel Velocity Scaling (265):	1.000000

The following commands make the mouse usable:

xinput --set-prop "Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)" "Device Accel Constant Deceleration" 1.5
xinput --set-prop "Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)" "Device Accel Velocity Scaling" 250

It would be nice if these defaults were set automatically.
