快滚加速器在Ubuntu 22.04 LTS中可通过xinput工具配置滚轮加速功能,首先安装依赖:sudo apt install xinput xprop
. 接着检测设备ID:xinput -m | grep pointer
,找到滚动设备(如ID 12),然后设置加速比例:xinput setprop " device name " Axis4 1200
(1200为加速值,范围0-2000),保存配置需编辑~/.Xmodmap
文件,添加`pointer = pointer 3 4 1200 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
