How to adjust scroll speed when using x11

[ytoaa]

I'm using termux with satisfaction, but there was no scroll control option other than xfce's mouse speed, and mouse speed control via xinput or imwheel failed. I'm trying everything on Samsung Dex, but... there was no way. Best, if you don't use mouse capture on x11, you can control mouse scrolling through Samsung Dex at least. But this is not a good option.
