I have the same issue. Mouse is Razer DeathAdder 2013. Mouse pointer speed setting works under gnome-shell, but under Unity it has no effect.

Attaching xinput props details.

I'm adding xinput props details too.

Thank you Ivan Larionov for pointing me to this xinput tool, which can also be used as a simple workaround : you can set the desired acceleration using "xinput --set-prop <device> <prop> <value>". To know the <device>, run "xinput" without arguments and look for your mouse device, then to know the <prop>, run "xinput --list-props <device>" and look for a property "Accel speed". For example, in my case (see previous attachment), "xinput --set-prop 11 282 0.2".

Same problem after updating to 17.04.
With a wireless logitech M185 and a "PixArt Microsoft USB Optical Mouse"

Setting the speed through xinput has no effect, but "xinput --list-props <device>" shows the updated value.

Changing mouse speed through GUI does not change the value listed by xinput.

Guilherme, are you sure xinput has no effect at all ?
The effect might not be noticeable unless you try more extreme values. Here the range is between -1 and +1, so zero seems to be some average.

Sorry for the delay, I was not receiving notifications.

So, now that you said I tried other values and setting speed through xinput is indeed working (at least for my Logitech M185 at home). I thought 0.0 was the lowest value. Setting to -0.5 slows it significantly.

Thank you Johan!

This is affecting me even on Kubuntu 17.04, on a fresh install.
