如何設定滑鼠"點選鎖定(長按)"功能 - Linux

之前有好心的人跟我說可以看
evdev 的 DragLockButtons ， /etc/X11/xorg.conf.d/
或是libinput

我看了這份文件
https://tinyurl.com/qooofev
還是不懂DragLockButtons的說明
它寫說如果只設一個值，代表"meta" locking button
設一對值,代表第一個值為lock button第二個值為logical button number
我想要設定滑鼠左鍵為DragLockButtons

我的設定文件似乎都是在/usr/share/X11/xorg.conf.d下
在/etc/X11下並沒有xorg.conf.d資料夾
但是我找不到"Log"Logitech USB Optical Mouse"的設定檔在哪
在目錄下用grep找也找不到

另外我從xinput list-props 9中沒看到ButtonMapping
所以參照下面這份文件試著用xinput set-prop來設定
也完全沒作用
https://wiki.archlinux.org/index.php/Logitech_Marble_Mouse

請問該怎麼設才對?
謝謝

以下是我的Ubuntu xinput list畫面

我不曉得Drag Lock Buttons要怎麼設定才是正確的?也有試過其他數字
如果設定xinput set-prop 9 281 136
會顯示BadValue(integer parameter out of range for operation)
root@sw-Veriton-M4610:~# xinput set-prop 9 281 2 2 (無作用)


root@sw-Veriton-M4610:/usr/share/X11/xorg.conf.d# ls

※ 引述《upufuxup (HelloRain)》之銘言：
: Windows 的滑鼠設定裡,可以啟動"點選鎖定",
: 讓使用者在反白或拖曳時,不須一直按著滑鼠,
: 只要按一下滑鼠鍵,放開,再按一次滑鼠鍵即可
: 我想要在Ubuntu裡也啟用這個功能
: 我查了imwheel跟xmodmap的設定教學,可是都找不到怎麼設定"點選鎖定"
: 請問有甚麼方法可以在Ubuntu上設定滑鼠"點選鎖定"?
: 謝謝
