Corsair M95游戏鼠标太敏感/速度太快。 如何降低速度？
鼠标控制面板窗口滑块什么都不做。 由于它的xinput道具不同，官方线程似乎不会影响这个特定的鼠标： 降低鼠标灵敏度
这是我尝试过的：
xinput set-prop 9 "libinput Accel Speed Default" 2.88 X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 131 (XInputExtension) Minor opcode of failed request: 57 () Serial number of failed request: 20 Current serial number in output stream: 21 和：
xinput set-prop $MOUSE_ID "Device Accel Constant Deceleration" 2.88 property 'Device Accel Constant Deceleration' doesn't exist, you need to specify its type and format
这是道具：
xinput list-props 9 Device 'Corsair Corsair M95 Gaming Mouse': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Accel Speed (287): 0.000000 libinput Accel Speed Default (288): 0.000000 libinput Accel Profiles Available (289): 1, 1 libinput Accel Profile Enabled (290): 1, 0 libinput Accel Profile Enabled Default (291): 1, 0 libinput Natural Scrolling Enabled (292): 0 libinput Natural Scrolling Enabled Default (293): 0 libinput Send Events Modes Available (272): 1, 0 libinput Send Events Mode Enabled (273): 0, 0 libinput Send Events Mode Enabled Default (274): 0, 0 libinput Left Handed Enabled (294): 0 libinput Left Handed Enabled Default (295): 0 libinput Scroll Methods Available (296): 0, 0, 1 libinput Scroll Method Enabled (297): 0, 0, 0 libinput Scroll Method Enabled Default (298): 0, 0, 0 libinput Button Scrolling Button (299): 2 libinput Button Scrolling Button Default (300): 2 libinput Middle Emulation Enabled (301): 0 libinput Middle Emulation Enabled Default (302): 0 Device Node (275): "/dev/input/event2" Device Product ID (276): 6940, 6918 libinput Drag Lock Buttons (303): libinput Horizontal Scroll Enabled (304): 1 jonny ~ xinput list-props 11 Device 'Corsair Corsair M95 Gaming Mouse': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Natural Scrolling Enabled (292): 0 libinput Natural Scrolling Enabled Default (293): 0 libinput Send Events Modes Available (272): 1, 0 libinput Send Events Mode Enabled (273): 0, 0 libinput Send Events Mode Enabled Default (274): 0, 0 Device Node (275): "/dev/input/event4" Device Product ID (276): 6940, 6918 libinput Drag Lock Buttons (303): libinput Horizontal Scroll Enabled (304): 1 jonny ~ xinput list-props 10 Device 'Corsair Corsair M95 Gaming Mouse': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Send Events Modes Available (272): 1, 0 libinput Send Events Mode Enabled (273): 0, 0 libinput Send Events Mode Enabled Default (274): 0, 0 Device Node (275): "/dev/input/event3" Device Product ID (276): 6940, 6918 jonny ~ xinput list-props 15 Device 'Corsair Corsair M95 Gaming Mouse': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Natural Scrolling Enabled (292): 0 libinput Natural Scrolling Enabled Default (293): 0 libinput Send Events Modes Available (272): 1, 0 libinput Send Events Mode Enabled (273): 0, 0 libinput Send Events Mode Enabled Default (274): 0, 0 Device Node (275): "/dev/input/event4" Device Product ID (276): 6940, 6918 xinput list-props 4 Device 'Virtual core XTEST pointer': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 XTEST Device (271): 1 xinput list-props 2 Device 'Virtual core pointer': Device Enabled (153): 1 Coordinate Transformation Matrix (155): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
和：
xinput 1 ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Corsair Corsair M95 Gaming Mouse id=9 [slave pointer (2)] ⎜ ↳ Corsair Corsair M95 Gaming Mouse id=11 [slave pointer (2)] ⎜ ↳ Razer Razer BlackWidow Ultimate id=13 [slave pointer (2)] ⎜ ↳ Razer Razer BlackWidow Ultimate id=14 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ UVC Camera (046d:0807) id=8 [slave keyboard (3)] ↳ Corsair Corsair M95 Gaming Mouse id=10 [slave keyboard (3)] ↳ Razer Razer BlackWidow Ultimate id=12 [slave keyboard (3)] ↳ Corsair Corsair M95 Gaming Mouse id=15 [slave keyboard (3)] ↳ Razer Razer BlackWidow Ultimate id=16 [slave keyboard (3)]
我非常接近：
xinput set-prop $MOUSE_ID "libinput Accel Speed" -0.9
哪里
MOUSE_ID=`xinput list | grep -i Corsair | awk '{print $(NF-3)}' | cut -c4-5 | head -n 1
Per： https ： //patrickmn.com/aside/lowering-gaming-mouse-sensitivity-in-ubuntu-9-10/
对于那些没有像我这样的Device Accel Constant Deceleration 。
libinput Accel Speed的值可以是负数，例如
xinput --set-prop 'pointer:Logitech MX Master' 'libinput Accel Speed' -0.5
要查找鼠标名称： xinput | grep pointer xinput | grep pointer ，不要忘记用pointer:作为前缀pointer:因为我的鼠标也显示为键盘。
