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): -1.000000 and libinput Accel
Profile Enabled (298): 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?
my settings:
xinput list
