找不到如何在 Ubuntu Studio 20.04 上禁用鼠标加速。
尝试：
$ xinput --list --short
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎜ ↳ KYE SYSTEMS CORP. Wired Mouse id=9 [slave pointer (2)]
$ xinput --list-props 9

可能改变加速度，并且它正在工作：
$ xinput --list-props 9 | grep 323
libinput Accel Speed (323): 0.100000
$ xinput --set-prop 9 323 0.5
$ xinput --list-props 9 | grep 323
libinput Accel Speed (323): 0.500000
尝试这样做，但它没有禁用鼠标加速：
$ xinput --list-props 9 | grep 326
libinput Accel Profile Enabled (326): 1, 0
$ xinput --set-prop 9 326 0, 0
$ xinput --list-props 9 | grep 326
libinput Accel Profile Enabled (326): 0, 0
