如何在 Raspberry OS / Debian 11 上禁用鼠标加速？

Question

我想在我的 RasPi 4 中完全禁用鼠标加速。从未使用过也不需要这样的功能。

• 设置Access Profile Enabled -1为我想法 https://www.x.org/wiki/Development/Documentation/PointerAcceleration/表明 - 显然我认为错了

每个选项都一一测试，首先重新加载 lightdm，然后由于没有更改而重新启动系统。

同样的鼠标在我的日常驱动程序以及 Debian 11（较低内核）上运行得非常好。

用 Gentoo 测试，没有任何鼠标延迟。 Debian ARM 版本有问题吗？
