Bug ID: 464459
Summary: Input-settings in xorg .conf files are overwritten by
plasma
Classification: Plasma
Product: plasmashell
Version: 5.26.5
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Startup process
Assignee: plasma-b...@kde.org
Reporter: mat.muel...@mailbox.org
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
I've tried setting a different mouse sensitivity for the touchpad (is treated
as a mouse though) on my wireless couch-keyboard. Works like a charm with
"xinput set-prop", but won't work when put into a xorg .conf file.
In the xorg-log, it seems to be applied, but when doing a 'xinput list-props
xx", it is back to the old value.
When trying "startx /usr/bin/xterm", it gets applied properly and is correctly
listed in list-props.
So it seems that plasma is doing something that overwrites these settings after
they are applied by X11.
Options that are affected from my experiments are at least "AccelProfile" and
"AccelSpeed", i haven't really tested other ones though.
I guess the options are applied according to what is set in the mouse section
of system settings - in there, there is no possibility to set separate values
for different mice though.
It seems there are a few other inactive bugreports that share the same origin:

https://bugs.kde.org/show_bug.cgi?id=357194
https://bugs.kde.org/show_bug.cgi?id=339743
STEPS TO REPRODUCE
1. create .conf file in "/etc/X11/xorg.conf.d"
2. Specify InputClass with AccelSpeed Option - my example:
Section "InputClass"
Identifier "touchpad-sens"
MatchDriver "libinput"
MatchIsPointer "true"
MatchProduct "2.4G Receiver"
Option "AccelProfile" "flat"
Option "AccelSpeed" "0.3"
EndSection
3. Reboot and see options not applied properly although reported as set in xorg
log

ADDITIONAL INFORMATION
Don't know if it matters, but i use SDDM and X11 session, haven't tried on
plasma-wayland yet though.
Also, i'm not sure if this is a plasmashell but or maybe kwin?
