14.04 LTS 启动器中的多个铬图标

Question

编辑 2014-04-19：
为我的问题添加一些额外的上下文，这些是我遵循的原始说明http://ricardofeliciano.me/how-to-create-a-unity-launcher-icon-for-each- chromechromium-profile-in-ubuntu/ . 在正式发布日期前几周，我让它与 Ubuntu 14.04 LTS 一起使用。4 月 17 日更新后，我无法再使用它：

原帖：
我在正式发布前几周安装了 Ubuntu 14.04 LTS 并设置了多个谷歌铬配置文件。使用“StartupWMClass”，我设法让每个配置文件在统一启动器中都有一个单独版本的铬图标（相同的图标，在启动器中单独出现）。在 14.04 正式发布后，我更新了所有软件包（包括 Chromium），从那以后我的附加 Chromium 配置文件不再在启动器上获得自己的图标位置，而是与主 Chromium 图标组合在一起。

这是我认为是我的设置的基本要素：

• 在~/.local/share/applications/我下面有我的 *.desktop 文件，其中包含以下几行
  • Exec=chromium-browser --user-data-dir=/home/<mydir>/.config/chromium/Profiles/<profile-name> --class=<profile-class-name> %U
  • StartupWMClass=<profile-class-name>
• 在/usr/share/applications/我安装铬时创建了默认的chromium-browser.desktop 文件，其中包含以下行
  • Exec=chromium-browser --class=Chromium-browser %U
  • StartupWMClass=Chromium-browser

添加--class=Chromium-browser到用于执行此技巧的默认安装 .desktop 文件的 Exec= 行，以便每个配置文件（包括默认配置文件）都与启动器上的它们自己的图标相关联。更新后，我不再能够让它工作。

我试过：

• 关闭所有铬窗，
• 从启动器解锁任何剩余的铬图标，
• 使用统一搜索启动默认的 Chromium Web 浏览器，
• 将出现的图标锁定到启动器
• 使用统一搜索启动额外的自定义 Chromium 配置文件
• --> 附加铬配置文件的窗口与为默认铬配置文件启动的图标相关联。他们使用相同的启动器图标。

我尝试重新启动 compiz，注销甚至重新启动我的计算机。

关于我可能缺少什么的任何提示？

ps 让我困惑的一件事是，我为 Google 日历创建的启动器File -> Create application shortcuts...按预期工作（使用它自己的不同图标），甚至没有使用--class=<profile>我认为必要的论点......

我想出了这个令人厌恶的东西（个人意见......我只是希望它能与 sh 一起工作:)）它有一些技巧，但对于两个 Windows 来说非常强大......你也可以指定更多的窗口，但是它们必须通过添加更多内容"specificprofile1"以及相应的功能来手动添加..也许有人可以使其具有更多..逻辑！

#!/bin/bash
# chromium-start.sh $1 
# e.g. put: 
# chrome-start.sh "Profile 1" to .desktop Exec=
# wmctrl -o 1366,0 ; chromium-browser %U --profile-directory=Profile\ 2 & sleep 3; wmctrl -o 0,0

# $1 = Profile folder name

profilename=$1

#2nd Chromium profile
specificprofile1="Profile 1"

echo "starting Chromium"
echo "args: " $1
echo "Profile name: " $profilename
echo "Specific profile: " $specificprofile1

# Just setting Chromium scaling variable, because of course Google Devs don't care about no fractional scaling on linux
scale_var=0.8

# Check if Chromium window with the specified class already exists
# Also allows using icons as "taskbar" switches (clicking icon takes to corresponding Chromium Window)
if wmctrl -l -x | grep "chromium-$profilename"
then
echo "Chromium Window exists, moving focus to it"
wmctrl -x -R chromium-"$profilename"
echo "true"

# Check if 2nd profile $specifiedprofile1 has been started yet or not. The WMCLASS(es) has to have been set correctly...
elif [[ "$specificprofile1" == "$profilename" ]] && [[ ! "`wmctrl -l -x | grep chromium-"$specificprofile1"`" ]]
then
    # TODO: Nesting
    if [ "$specificprofile1" == "$profilename" ]
    then
    echo $specificprofile1 "equals" $profilename
    fi
echo "#2 Chromium Window for $specificprofile1 does not exist"
# wmctrl moves to specific position of desktop (1366 means moving to the following workspace since my resolution is 1366x768)
# Be careful if using sleep timing, since the command needs to have enough time to execute to have the window in the correct workspace

问题：

打印给出错误（弃用警告..）：

Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/%{ <-- HERE (.*?)}/ at /usr/bin/print line 528.

为了调试，您可以使用以下命令打印使用实际图标时的错误： https://askubuntu.com/a/664272/654028（# 手动替代方案）

awk '/^Exec=/ {sub("^Exec=", ""); gsub(" ?%[cDdFfikmNnUuv]", ""); exit system($0)}' chrome-ws2.desktop

while 循环出错，可能是因为循环间隔

Error: no such file "at while function"
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .
xwininfo: error: -id requires argument
xprop: error: Invalid window id format: .

此外，当单击相应的 .desktop 图标太快时（在设置自定义类之前？），将打开一个新窗口。

（相当）有时，当从两个 Chromium 启动太快（~<3s）时，之前打开的窗口的类会重置为 chromium-browser.chromium-browser.. 然后你可以预期图标会交换或其他意外行为。
