如何禁用最大化窗口的热角

我在左上角有一个热角，用于显示所有窗口，在右下角有一个热角，用于显示工作区。玩游戏时这些热角不断激活很烦人。有没有办法设置 Compiz 在全屏窗口时忽略热角？

答案1

下面有两个选项；一个脚本用于在活动窗口最大化时禁用所有热角（暂时），另一个脚本用于仅禁用您在问题中提到的特定热角和操作。

这两个脚本都非常轻量，不会给您的系统添加任何明显的负担。

1. 禁用全部如果活动窗口是全屏的，则显示热角

下面的背景补丁将禁用全部如果（并且只要）活动窗口最大化（全屏），则热角。

edgedata = os.path.join(os.environ["HOME"], ".stored_edges")
key = "/org/compiz/profiles/unity/plugins/"
corners = [
    "|TopRight", "|TopLeft", "|BottomLeft", "|Right",
    "|Left", "|Top", "|Bottom", "|BottomRight",
    ]

def get(cmd):
    # just a helper function
    try:
        return subprocess.check_output(cmd).decode("utf-8").strip()
    except subprocess.CalledProcessError:
        pass

def setval(cmd):
    # just another helper function
    subprocess.Popen(cmd)

def check_win():
    # see if the active window is maximized
    # get the active window, convert the id to wmctrl format
    windata = get(["wmctrl", "-lG"])
    if windata: 
        w = hex(int(get(["xdotool", "getactivewindow"])))
        front = w[:2]+((10-len(w))*"0")+w[2:]
        # look up the window size
        match = [l for l in windata.splitlines() if front in l][0].split()[4:6]
        # and compare them, if equal -> window is maximized
        return match == res

def get_res():
    # look up screen resolution
    scrdata = get("xrandr").split(); resindex = scrdata.index("connected")+2
    return [n for n in scrdata[resindex].split("+")[0].split("x")]

def get_edges():
    # get data from dump, remember 
    data = get(["dconf", "dump", key]).split()
    for s in data:
        if s.startswith("["):
            k = s.replace("[", "").replace("]", "/")
        elif any([[c in s][0] for c in corners]):
            currval = s.split("=")
            stored = ["dconf", "write", key+k+currval[0], currval[1]]
            tempval = ["dconf", "write", key+k+currval[0], "''"]
            open(edgedata, "a+").write(str(stored)+"\n")
            setval(tempval)

def set_stored():
    # set the stored values
    try:
        prev = open(edgedata).readlines()
    except FileNotFoundError:
        pass
    else:
        for l in  [l.strip() for l in open(edgedata).readlines()]:
            toset = ast.literal_eval(l)
            setval(toset)
        os.remove(edgedata)

res = get_res()
state1 = None

while True:
    time.sleep(1)
    state2 = check_win()
    if state2 != None:
        if state2 != state1:
            get_edges() if state2 else set_stored()
        state1 = state2

如何使用

  1. 该脚本需要xdotool和wmctrl：

    sudo apt-get install wmctrl xdotool
  2. 将脚本复制到一个空文件中，并将其保存为disable_corners.py

  3. 使用以下命令从终端运行脚本：

    python3 /path/to/disable_corners.py

  4. 如果一切正常，请将其添加到启动应用程序：Dash > 启动应用程序 > 添加。添加命令：

    /bin/bash -c "sleep 10 && python3 /path/to/disable_corners.py"

2. 如果活动窗口为全屏，则仅禁用特定边缘

如果活动窗口最大化，下面的（背景）脚本将禁用您提到的两个角落操作。

        front = w[:2]+((10-len(w))*"0")+w[2:]
        # look up the window size
        match = [l for l in windata.splitlines() if front in l][0].split()[4:6]
        # and compare them, if equal -> window is maximized
        return match == res

def get_res():
    # look up screen resolution
    scrdata = get("xrandr").split(); resindex = scrdata.index("connected")+2
    return [n for n in scrdata[resindex].split("+")[0].split("x")]

res = get_res()
state1 = None

while True:
    time.sleep(1)
    state2 = check_win()
    if state2 != None:
        if state2 != state1:
            newws = "''" if state2 else active1
            # below the specific edges to take care of
            setval(["dconf", "write", key+"/expo/expo-edge", newws])
            newspread = "''" if state2 else active2
            setval(["dconf", "write", key+"/scale/initiate-edge", newspread])
        state1 = state2

如何使用

使用和设置与选项 1 完全相同。

解释

  • 在脚本启动时，脚本会检查屏幕的分辨率。
  • 该脚本每秒检查一次活动窗口的大小，并将其与屏幕的分辨率进行比较。
  • 如果窗口大小和分辨率相等，则窗口显然最大化。

  • 如果有改变在情况（最大化/非最大化）下，脚本使用以下命令设置/取消设置热角：

    dconf write /org/compiz/profiles/unity/plugins/expo/expo-edge "''"

dconf write /org/compiz/profiles/unity/plugins/scale/initiate-edge "''"

    禁用，或

    dconf write /org/compiz/profiles/unity/plugins "'|BottomRight'"

dconf write /org/compiz/profiles/unity/plugins "'|TopLeft'"

    启用。
