<div dir="ltr"><div dir="ltr"><div>I have problems with mouse sensitivity settings. I am using Debian stable and bullseye,Ubuntu 18.04.4, 20.04 LTS. I use the default mouse acceleration profile and the mouse speed is set to the minimum value. But a few seconds after setting these values, the mouse speed changes without my permission. So i go to terminal and use command xinput list-props 11 and i got the same "libinput Accel Speed (295):<span style="white-space:pre"> </span>-1.000000 and libinput Accel Profile Enabled (298):<span style="white-space:pre"> </span>1, 0" But this value match to minimal mouse speed and default mouse accel profile. Those settings didn't changed, but mouse speed is different. Why this happends?</div><div>my settings:</div><div>xinput list</div><div>⎡ Virtual core pointer <span style="white-space:pre"> </span>id=2<span style="white-space:pre"> </span>[master pointer
