尝试关闭ubuntu通知时列出索引超出范围

Question

我正在使用Ubuntu 16.04我正在寻找一个表单来关闭ubuntu通知。我找到了下面的脚本，但是当我运行它时，我收到了错误：

Traceback (most recent call last):
    File "manage_notifications.py", line 6, in <module>
    ["xrandr"]).decode("utf-8").split() if "+0+0" in s][0]
IndexError: list index out of range

有谁知道出了什么问题？ 剧本：

#!/usr/bin/env python3
import subprocess
import time

w = int([s.split("x")[0] for s in subprocess.check_output(
    ["xrandr"]).decode("utf-8").split() if "+0+0" in s][0]
        )

def get_mouse():
    loc = subprocess.check_output(["xdotool", "getmouselocation"]).decode("utf-8").split()[:2]
    return [int(n.split(":")[1]) for n in loc]

while True:
    time.sleep(1)
    try: 
        subprocess.check_output(["pgrep", "notify-osd"]).decode("utf-8")
        curloc1 = get_mouse(); t = 1
        while t < 10:
            time.sleep(1)
            curloc2 = get_mouse()
            test1 = curloc1[0] > w - 400 and curloc1[1] < 400
            test2 = curloc2[0] > w - 400 and curloc2[1] < 400
            if all([test1 == False, test2 == True]):
                subprocess.Popen(["pkill", "notify-osd"])
                break
            curloc1 = curloc2
            t = t+1
    except:
        pass

我是否需要更改python脚本中的内容以匹配我的机器配置？
