The logging is super confusing. The output of xinput properties gives me three numbers (0,1,0). i think i read somewhere online that the second number indicates the "off" status. so in theory mouse accel should be off but im unsure to be honest. additionally the part in xorg.log that states a fallback profile will be used because "step value 0 is provided" (no idea).
The instructions on this page https://www.x.org/wiki/Development/Docu … eleration/ correspond with the alternative method in the wiki that "does not use libinput" (?) but the Option "AccelSpeed" is nowhere mentioned in the whole article.
...I just realized that the wiki article is borked.
I'll try to follow the instructions in the Talk/Discussion
If someone knows how to have the same settings on Linux like when you turn OFF "Enhance Pointer Precision" in Windows, so presumably no deviation whatsoever, please share.
Im not a noob but if someone wants to move this post to Newbie Corner i can understand ofc.
SOLUTION:
firstly my user wasnt added to the "input" group...
gpasswd -a username inputthen i could see what the numbers showing for the "libinput Accel Profile Enabled" from xinput actually mean with running

Accel profiles: n/a
Rotation: 0.0so the first number means FLAT, the second means ADAPTIVE and the third means CUSTOM.
and the star "*" in front of "adaptive" seems to indicate that is the default option (at first i thought this indicates the currently active profile but that is not the case).
there are countless tutorials online (like on youtube for ubuntu), where the correlation of the numbers and profiles are different. okay this might be hardware related or people just experience another kind of reverse placebo, thinking accel is off when it isnt. which is likely because they also use libinput im sure.
then i issued this command
xinput --set-prop 14 "libinput Accel Profile Enabled" 1 0 0and now to check if the profile has changed:
# xinput list-props 14

Alternatively i can also make this setting permament by editing "/usr/share/X11/xorg.conf.de/40-libinput.conf", changing this section:
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
EndSectionto ->
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Accel Profile Enabled" "1 0 0"
EndSectionagain the order of numbers may vary for other devices.
i chose to put this in /usr/share/X11/xorg.conf.d and NOT! /etc/X11/xorg.conf.d because it was mentioned in the Talk/Discussion. i dont know why but it makes sense because there is already a working entry there catching every mouse.
Whats also important to note is that when using the xinput one liner the three numbers are separate arguments to the command but when putting it in the xorg configuration file you merge it together into one string.
imo the only way to really make sure accel is off is to run some analyzer program (for windows there is this monitoring tool packaged with "mark c mousefix" that shows acceleration in real time). i dont know if something like this exists for linux (evhz only gives you polling rat).
i would like to delete the wiki article. at least the code snippets that supposedly disable accel. only saying "the factual accuracy of this article is disputed" mislead me to believing i could still find some useful help there but all the useful stuff is in the Talk/Discussion.
how about replacing the section for disabling mouse acceleration with these 3 simple steps:
1. make sure you are part of the input group
2. check the corresponding profiles for your device with libinput list-props
3. run the xinput one liner at startup (from .xinit should work for example [if you use automatic startx] or other autostart procedures)
or
3. make settings permament in /usr/share/X11/xorg.conf.d
with some nice formatting (this is a rant) that would surely help the other people trying to figure out how to disable accel for real.
Final Note: When i used (like the false wiki section supposes)
"Option" "AccelProfile" "flat"in 40-libinput.conf i still had the second profile (adaptive) enabled. DONT USE THIS. USE THIS FORMAT INSTEAD
Option "Accel Profile Enabled" "1 0 0"(with your corresponding profile). id not be surprised if the order of profiles is always FLAT,ADAPTIVE,CUSTOM for everyone because libinput seems to be well structured unlike this post and the mouse accel wiki.
To give an example of how deep this goes, check the bug report on the bottom of the wiki https://bugs.kde.org/show_bug.cgi?id=468217#c3
There are recent posts from 2023 where people follow the wiki and use/suggest
Option "AccelProfile" "flat"
Option "AccelSpeed" "0"As I understand it these options are either deprecated or just plain wrong, and everyone looks up issues like this on the archwiki, so misinformation spreads.
I cannot imagine that this would work when it clearly did not do anything for me, which can be confirmed with xinput list-props. Its just hard to figure out if a slight bit of acceleration is active or not. please correct me if im wrong.
EDIT: I was wrong. The order of profiles given by "libinput list-devices" does not correlate to the configuration with xinput. the first number is the default acceleration profile, the second number is the flat profile and the third number must be the custom profile. still, the "old" method of assigning the values in the xorg configuration file was wrong/deprecated. I corrected the entry in the wiki.
i checked the acceleration values with an online measuring tool and using "1 0 0" i got significantly higher acceleration values compared to "0 1 0". i wonder if there is some documentation for the number system with xinput because the meaning of the values is not provided in any place i looked up.
