linux下的鼠标滚动设定

不知道为什么，总感觉在linux下鼠标不顺滑，滚动起来特费劲。同理google之，记之备用

sudo apt install imwheel;touch ~/.imwheelrc 

".*"
None, Up, Button4, 3
None, Down, Button5, 3
Control_L, Up, Control_L|Button4
Control_L, Down, Control_L|Button5
Shift_L, Up, Shift_L|Button4
Shift_L, Down, Shift_L|Button5

然后运行imwheel即可
