无法更改鼠标灵敏度

Question

系统: Debian 11 Bullseye

DE: XFCE或KDE

在鼠标设置中只有一个加速滑块(仅加速)。

在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。改变新闻部不是一种选择。

我有几只不同的老鼠--同样的结果。

Answer 1

经过一番搜索，我意识到libinput有不同的加速道具：

libinput Accel Profiles Available
  2 boolean values (8 bit, 0 or 1), in order "adaptive", "flat". Indicates which acceleration profiles are available on this device.
libinput Accel Profile Enabled
  2 boolean values (8 bit, 0 or 1), in order "adaptive", "flat". Indicates which acceleration profile is currently enabled on this device.

因此，我可以通过以下方式禁用加速(启用平面配置文件)：

xinput --set-prop 8 304 0, 1 

其中8是我的鼠标id，304是"libinput Accel配置文件已启用“属性。

现在我可以通过更改"libinput Accel速“标志来控制灵敏度。
