系统：Debian 11 Bullseye
DE：XFCE 或 KDE
鼠标设置中只有一个加速滑块（仅加速）。
并且xinput中没有加速配置文件或模式标志。我有加速标志：
libinput Accel Speed (301): 1.000000
libinput Accel Speed Default (302): 0.000000
libinput Accel Profiles Available (303): 1, 1
libinput Accel Profile Enabled (304): 1, 0
libinput Accel Profile Enabled Default (305): 1, 0
如果我用 xinput 禁用加速，我根本无法改变灵敏度。更改 DPI 不是一种选择。
我有几个不同的鼠标 - 结果相同。
