是否可以在 Wayland 下启用焦点窃取？（侏儒外壳 3.26，Ubuntu 17.10）

好吧，不确定这个错误是否只发生在我的机器上，或者它是否更普遍。我可能是错的，但我猜这可能是由于一些 Wayland 安全限制阻止应用程序聚焦已经打开的窗口（据我所知，窗口管理器现在应该处理这些事情，而不是 X 中的显示服务器)。我假设这是一个过渡性问题，gnome 最终将使 gedit 能够专注于新选项卡。

在等待此修复程序时，我想出了一个部分修复程序，当在 gedit 中打开新选项卡时会发送通知。这并不能解决自动对焦问题，但至少它会给你一些提示，这样你就不会坐在那里 2 或 3 秒想知道为什么你的窗口还没有打开。

在非 root 终端中，输入：

gedit admin:///usr/bin/gedit-notify

在gedit-notify中，粘贴以下脚本：

#!/bin/bash
# purpose of this script: gedit under gnome Wayland has pretty messed up focusing and activation problems. First document/tab opened will focus normally but all the following ones open in the background without the traditional notification: "Your window is now read, click to focus". Its very distracting behavior because for the first 2 seconds you're wondering if your click was registered or not, if the app opened or not, etc. This script sends a notification every time you open a text file in the background. 

skip_list=true # you get notified but your notification list doesn't get spammed.

    gedit_inst=$(ps ax|grep " gedit "|wc -l)      #total number gedit windows + 1
    gedit_inst=$(expr $gedit_inst - 1)          #remove one from the count to account for the grep " gedit " process
    gedit_s=$(ps ax|grep " gedit -s"|wc -l)         # -s switch represents signle / independent instance for gedit. 
                                                # gedit_s represents the number of gedit windows running as 
                                                # independent instances + 1
    gedit_s=$(expr $gedit_s - 1)                # same logic as before
    gedit_inst=$(expr $gedit_inst - $gedit_s)   #substracts the # of windows running in independent instances 
                                #from total cound - because they don't affect the focus behavior. 
    if [ "$skip_list" = true ]; then
        n_arg0="--hint";n_arg1="int:transient:1"
    else
        n_arg0="-u";n_arg1="low"
    fi

    if [ "$gedit_inst" = 0 ]; then notify=false;fi 

n=0
while true; do
    n=$(expr $n + 1)
    file=$(eval echo \$$n)
    if ! [ -z "$file" ]; then 
        gedit "$file" &
        if [ -z "$err" -o "$err" = 0 ]; then 
                err="$?"
        fi
    else
        count=$(expr $n - 1) 
        if [ $count = 0 ]; then 
            if [ "$notify" != false ]; then notify-send $n_arg0 $n_arg1 "TEXT EDITOR is ready. Activate it manually.";fi
            gedit
        fi
        break; 
    fi          
done

if [ "$err" = 0 -a "$notify" != false ]; then 
    if [ $count -gt 1 ]; then
        notify-send $n_arg0 $n_arg1 "TEXT EDITOR is ready. Activate it manually." "$count files were opened."
    elif [ $count = 1 ]; then
        notify-send $n_arg0 $n_arg1 "TEXT EDITOR is ready. Activate it manually." "file: \"$1\""
    fi
elif [ "$err" != 0 ]; then
    notify-send -i error "TEXT EDITOR: I ran into some error(s) while opening your file(s)."
fi

保存gedit-notify，然后输入：

cd /usr/bin
sudo chmod +x gedit-notify; sudo touch gedit-notify
gedit admin:///usr/share/applications/gedit-notify.desktop

在gedit-notify.desktop中，粘贴以下代码：

[Desktop Entry]
Name=Text Editor (Notify)
Comment=Edit text files

这将创建一个桌面快捷方式，该快捷方式将在仪表板和打开方式菜单中显示为文本编辑器（通知）。在nautilus中，四处浏览，找到一个文本文件，右键单击它，选择属性，单击打开方式选项卡，选择“文本编辑器（通知）”，设置为默认值。将有 4 或 5 种不同类型的文本文件需要重复此过程。冲洗并重复。
