执行 busctl list |grep dde-launcher 返回为空, 手动启动dde-launcher后, 再执行 busctl list |grep dde-launcher 就有返回结果,且能打开启动器

$ busctl list |grep dde-launcher  # 返回结果为空
$ nohup dde-launcher &  # 替换成dde-launcher-wapper可达到一样的效果
[1] 9373
nohup: 忽略输入并把输出追加到'/home/microops/nohup.out'
$ busctl list |grep dde-launcher # 手动启动dde-launcher后就有返回结果
