Ubuntu 16.04.1 Cant disable mouse acceleation


So I upgraded to gnome 3.20. Reason is gnome kept overriding my nvidia x server settings after every reboot. Upgrading and setting the refresh rate in the new menu fixed the problem. I have found that my way of disabling mouse acceleration does not work.

System info
Clean install of ubuntu gnome 16.04.1 (from the gnome website)
Upgrade to gnome 3.20

To try to resolve the mouse acceleration issue I did the following

sudo vim /usr/share/X11/xorg.conf.d/90-mouse.conf

Then put the following into the files and saved it.

Section "InputClass"
Identifier "mouse"
MatchIsPointer "on"
Option "AccelerationProfile" "-1"
Option "AccelerationScheme" "none"
EndSection


After saving the file and restarting mouse acceleration re appears.

I double checked that the file saved and yes it had, Any ideas on how to fix this?

Try comment out the Acceleration lines like this:

# Option "AccelerationProfile" "-1"
# Option "AccelerationScheme" "none"

restart X <Ctl+Alt+Backspace> or just plainly logout and login.

See if the issue disappears.

Two other ways to try and configure mouse acceleration are "xinput" and "xset"

https://wiki.archlinux.org/index.php/Mouse_acceleration

I haven't messed with mouse acceleration settings, but I have generally had a lot of success with using xinput to modify settings for mouse, wacom stylus, and touchscreen input. I have only used xset for things like turning off screen blanking or manually screen blanking.

Note that xinput settings do not "persist". You can create a bash script to run various xinput settings and set that script to automatically run on session startup. (I'm not a GNOME user, so I don't know exactly where you do that.) It'll look something like:
Code:
#!/bin/sh
sleep 5
xinput set-button-map "Logitech Unifying Device. Wireless PID:400a" 1 2 3 4 5 0 0 6 7
xinput set-prop "Serial Wacom Tablet FUJ02e5 stylus" "Wacom Rotation" 3
xinput set-prop "Serial Wacom Tablet FUJ02e5 stylus" "Wacom Tablet Area" 300, 250, 28708, 18080
xsetwacom set "Serial Wacom Tablet FUJ02e5 stylus" MapToOutput LVDS1
xsetwacom set "Serial Wacom Tablet FUJ02e5 eraser" MapToOutput LVDS1
I include a 5 second delay at the start just in case XFCE4 (in your case GNOME) is doing stuff in the first few seconds that might get confused if my xinput commands start firing off to early.

Your xinput commands will differ, of course.

I found the problem.

It turns out gnome 3.20 is now forcing mouse accel on. None of the fixes work except for doing a clean install of Ubuntu gnome 16.04.1 LTS using gnome 3.18. After the reinstall and applying my usual fix mouse accel is gone. I submitted a bug report on gnomes bug reporting feature. Thanks to everyone who suggested things.
