Description:
Mouse scroll stopped working after one of latest system updates. It is not working at all in any application. I tried command which shows mapping of all buttons in mouse and it looks like mouse scroll is not visible for system at all (3rd button is detected but scroll not) I tried change xorg.conf options but result of any change is that computer stop during boot. Below is my 40-libinput.conf mouse section with options what I tried to on.

Section "InputClass"
Identifier "libinput pointer catchall"
#Identifier "mouse0"
#Name "A4Tech PS/2+USB Mouse"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event4"
#MatchDevicePath "/dev/input/mouse0"
#ZAxisMapping "4 5"
#Buttons "6"
Driver "libinput"
#Driver "evdev"
EndSection

orginally option MatchDevicePath was "/dev/input/event*"
I got 50-vmmmouse.conf in system as well:

Section "InputClass"
Identifier "vmmouse"
MatchIsPointer "on"
MatchTag "vmmouse"
Driver "vmmouse"
EndSection

this is rersult of egrep "Name|Handlers" /proc/bus/input/devices | egrep -B1 'Handlers.*mouse' command

N: Name="A4Tech PS/2+USB Mouse"
H: Handlers=event4 mouse0

Kernel 4.19.49-1 LTS

Scroll is working normally on kernel version 4.19.37-1 LTS

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any

Have you reported the issue upstream or determined which commit was the cause?

Can you tell me how to determine which commit was the cause? Probably there is a step by step guide somewhere. I've never done it before. =\

First can you determine if any of the kernels between 4.19.37-1 and 4.19.49-1 were affected? If you do not have the packages required you can obtain them from [1].

Seems like it's related to upstream bug https://bugzilla.kernel.org/show_bug.cgi?id=204179

https://patchwork.kernel.org/patch/10986697/ applied to 4.19.60
@cezarclaude  FS#63211  for linux-zen / linux

I believe the causal commit was f7ab4818f74e4d7e796b59fe847de12beb7063b3 which was added in v4.19.44

I know about this patch, and this patch is working well but I have no idea how I can apply this patch, I did not try to do it, simply I did have got any problems with hardware on Arch yet. If You got any tutorial how to apply patch I would be very thankful.
