使用 Deepin 过程中，发现当点击“任务栏”上面的按钮，尤其是右键单击，选择菜单时，界面很容易卡顿，再也动弹不了。
好吧，，，就不使用自带的“任务栏”了，换成一个轻量级的“任务栏tint2”，
1、隐藏自带的"任务栏"
右键单击"任务栏"，
(1) 模式 -> 选择“高效”
(2) 位置 -> 选择“左”
(3) 大小 -> 选择“小”
(4) 状态 -> 选择“一直隐藏”
2、安装 tint2，打开终端（Ctrl+Alt+T），然后输入下面的命令
sudo apt-get install -y tint2
3、配置 tint2
(1) 按住 Super 键，会看到如下 2 个图标
(2) 设置“开机启动”
如下图所示，右键单击，选择菜单“开机自动启动”
(3) 选择“主题”
单击上图2，有2个主题可选，这里我选一个“扁平化”风格的主题，然后点击按钮“Make default”
(4) 设置 “启动器”快捷按钮
上图，点击按钮“Edit Theme”，选择“Launcher”选项卡，从右边的“Application available”中，选择常用的软件图标，然后会出现在“Application selected” 面板中，中间的 上、下、左、右 可用调整选项和上下位置。
最左边的“启动器”效果图：
(5) 调整右键单击任务栏图标行为
默认情况下，右键单击任务栏图标，会关闭该软件，，，可以到“Task buttons ”选项卡中，调整这一行为，找到 “Right click”， 选择“None”。
(6) 更改“激活的”任务栏图标的字体颜色为“黄色”
(7) 调整“任务栏”左右边距（其实是调整任务栏的长度）
Panel -> Geometry -> Length，填入92，单位下拉“Percent”
注意：因为 屏幕的四个角都有可触发动作的锚点，为避免冲突，所以任务栏的长度不要设置为 100%
(8) 调整右下角时间格式
Clock -> Format -> First line format: %H:%M %a，Second line format: %Y/%m/%d
显示秒，First line format 值为：%H:%M:%S %a
显示效果：
(9) 任务栏图标排序方式
Taskbar -> Task sorting -> 选择“None”
(10) 不显示“任务栏”名称
Taskbar -> Desktop name -> 去掉勾选“Show desktop name”
后续说明：
自从不用 Deepin 自带的“任务栏”后，再也没遇到卡顿的现象！
