Linux Mint Cinnamon 上的类似 macbook 的多点触控触控板，带有 touchegg

我正在尝试在我的 Linux 机器上使用类似 macbook 的多点触控触控板手势。目前正在研究 Linux Mint 18，试图让 touchegg 工作，但如果它工作正常，我愿意接受另一个多点触控系统。机器是戴尔Latitude E7450。我知道系统在某种程度上意识到了多点触控，但它似乎没有在 touchegg 中得到正确处理。

触控板类型 : ALPS

egrep -i 'synap|alps|etps|elan' /proc/bus/input/devices           
N: Name="AlpsPS/2 ALPS DualPoint Stick"
N: Name="AlpsPS/2 ALPS DualPoint TouchPad"

触控板能够进行多点触控

xinput list-props 13 
[snip]
Synaptics Capabilities (295):   1, 1, 1, 1, 1, 0, 0
[snip]

系统的某些部分知道我所做的触摸

当我跑步时

sudo evtest /dev/input/event8 | grep "code 33"

我很好地看到我的单次触摸出现（触摸时出现第一行，放开时出现第二行）：

Event: time 1487946648.539316, type 1 (EV_KEY), code 330 (BTN_TOUCH), value 1
Event: time 1487946649.722918, type 1 (EV_KEY), code 330 (BTN_TOUCH), value 0

对于两根手指触摸，我在接触时得到 2 条线，在放开时得到 2 条线（我认为这是因为我的手指没有在完全相同的时刻进行/断开接触）

Event: time 1487946869.652686, type 1 (EV_KEY), code 330 (BTN_TOUCH), value 1
Event: time 1487946869.666681, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 1

Event: time 1487946873.257236, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 0

但是，当我同时触摸 3 个或 4 个手指时，我会得到如下输出：

持续不断，而且速度极快。

touchegg 命令行

当我在命令行上运行 touchegg 时，我会得到可用手势的列表，但当我尝试执行手势时不会打印任何内容。如果我第一次运行（按照建议https://askubuntu.com/questions/266057/cant-get-touchegg-to-work-with-my-touchpad）

synclient TapButton2=0
synclient TapButton3=0
synclient ClickFinger2=0
synclient ClickFinger3=0
synclient HorizTwoFingerScroll=0
synclient VertTwoFingerScroll=0

然后我在命令行上再次运行 touchegg ，我确实得到了一些输出，但它似乎无法识别第三个和第四个手指。我不断收到类似的东西

[+] New gesture: 
    Type      ->  "DRAG" 
    Fingers   ->  2 
    Direction ->  "UP" 
    Action    ->  "SCROLL" 
    App Class ->  "Gvim" 
    Gesture Start 
    Gesture Update 0 "Drag" 
    Gesture Update 0 "Drag" 
    Gesture Update 0 "Drag"

在输出中。即使对于 3 和 4 根手指触摸，它也会给出“手指 -> 2”部分。

那么接下来我可以尝试什么才能让多点触控手势在 MacBook 上以 macOS 使用的风格工作呢？
