Hello everyone. Ever since I upgraded to Ubuntu 14.04 I cannot use (xinput set-prop 'Device Accel Profile' -1 xinput set-prop 'Device Accel Velocity Scaling' 1) to disable mouse acceleration. It seems xinput doesn't recognise my mouse correctly.

xinput list shows

and xinput list-props 10 shows

Whenever I try to set the values above manually I get an error: property 'Device Accel Velocity Scaling' doesn't exist, you need to specify its type and format

I would kindly appreciate any help.
