[Request] Add additional mouse settings for disabling mouse acceleration and middle click emulation [$350]

[heew]

As was done in Gnome 3.22 (see https://www.reddit.com/r/linux_gaming/comments/553v1p/gnome_322_includes_option_to_disable_mouse/) we should be able to disable these settings from the GUI and not be forced to use xinput --list and xinput --set-prop.

It really is not good for gaming to have mouse acceleration and I cannot get X to respect any of my .conf files to this (even after following the "man xorg.conf.d").

Image here shows how Gnome has it in the GUI: https://imgur.com/a/DYdUO.

I am currently working around this with a self-made script that I run prior to gaming, but I feel this should be more easier to work around.

Keep up the great work with MATE and I hope we can make it better!

Some additional information..

From man xorg.conf.d:

       Xorg uses a configuration file called xorg.conf and files ending in the suffix .conf from  the  directory  xorg.conf.d  for  its  initial  setup.   The
       xorg.conf configuration file is searched for in the following places when the server is started as a normal user:

           /etc/X11/<cmdline>
           /usr/etc/X11/<cmdline>
           /etc/X11/$XORGCONFIG
           /usr/etc/X11/$XORGCONFIG
           /etc/X11/xorg.conf
           /etc/xorg.conf
           /usr/etc/X11/xorg.conf.<hostname>
           /usr/etc/X11/xorg.conf
           /usr/lib/X11/xorg.conf.<hostname>
           /usr/lib/X11/xorg.conf

So that means I should be able to add the following file and it should have kept the settings persistent:

[root@tower:~]# cat /etc/xorg.conf 
Section "InputClass"
	Identifier "ZOWIE EC-2 A"
	MatchDriver "libinput"
	MatchIsPointer "on"
	Option "AccelProfile" "flat"
	Option "MiddleEmulation" "off"
EndSection
[root@tower:~]#

I have also tried with this file:

[root@tower:~]# cat /etc/X11/xorg.conf.d/95-mouse-fix.conf 
Section "InputClass"
	Identifier "ZOWIE EC-2 A"
	MatchDriver "libinput"
	MatchIsPointer "on"
	Option "AccelProfile" "flat"
	Option "MiddleEmulation" "off"
EndSection
[root@tower:~]# 

So it seems MATE does not fully follow the run-parts listed in "man xorg.conf.d"?

According to how I read it it should have been included:

[root@tower:~]# run-parts --list /etc/X11/xorg.conf.d/
/etc/X11/xorg.conf.d/00-avoid-glamor.conf
/etc/X11/xorg.conf.d/00-keyboard.conf
/etc/X11/xorg.conf.d/95-mouse-fix.conf
/etc/X11/xorg.conf.d/99-nvidia.conf
[root@tower:~]#

99-nvidia.conf contents:

[root@tower:~]# cat /etc/X11/xorg.conf.d/99-nvidia.conf
#This file is provided by xorg-x11-drv-nvidia
#Do not edit

Section "Files"
	ModulePath   "/usr/lib64/nvidia/xorg"
	ModulePath   "/usr/lib64/xorg/modules"
EndSection
[root@tower:~]#

This particular issue could be related to #133, but there should really be a simple GUI option to do this.

Here is how I currently work around it - each time before gaming I run the following script:

[howard@tower:~]$ cat bin/mouse_fix.sh 
#!/usr/bin/bash
xinput --list | sed -ne 's/^[^ ][^V].*id=\([0-9]*\).*/\1/p' | while read id
do
	case  `xinput --list-props $id` in
        *"libinput Middle Emulation Enabled ("*)

            # turn off middle mouse emulation
			emulation_id=$(xinput --list-props $id |grep 'libinput Middle Emulation Enabled (' |egrep -o "\([0-9]{1,}\)" |sed 's/(\|)//g')
			xinput --set-prop $id $emulation_id 0

            # turn off mouse acceleration
            maccel_id=$(xinput --list-props $id |grep 'libinput Accel Profile Enabled (' |egrep -o "\([0-9]{1,}\)" |sed 's/(\|)//g')
            xinput --set-prop $id $maccel_id 0 1
		;;
	esac
done
[howard@tower:~]$ 

I was surprised that my xorg.conf.d file is not being respected, but as previously mentioned I think there should be a GUI way of doing this - similar to how Gnome 3.22 did.

I have tried to add the script to start up applications and crontab that fails - I assume because it does not detect X.

This will be easily achievable as soon as Mate will move to GTK3.4

[flexiondotorg]

MATE is all GTK3 now. Minimum version is 3.14.

[snaiperskaya96]

Ye, I know, and what im saying is that if mate will raise the gtk version to 3.4 there will be an option available to let gnome handle the middle mouse button

3.4 is less than 3.14.

Forgive my 6pm dumbness... Will look into it 2017-08-08 18:37 GMT+01:00 Martin Wimpress <notifications@github.com>:

No problem ☺️

[heew]

Any updates on this?

[tom-seewald]

I'm guessing they are waiting for more money to be added to the bounty.

[zodywoolsey]

While I was looking through some similar issues and some of the code it appears that what is requested has been added. Is this the case? Were the appropriate individuals rewarded the bounty as promised? If not, I might be up to attempting to solve this issue.

[Neverest]

@zodywoolsey From what I have seen, a GUI option to disable mouse acceleration has not ben added.

[vkareh]

I've submitted several patches to fix this. All three are needed for this to work:

• schema: Move mouse schemas to mate-settings-daemon mate-desktop#407
• mouse: Add acceleration profiles mate-settings-daemon#293
• mouse: Add support for Acceleration Profiles #494
