应该是个bug？ @babyfengfjx

以前也有人提过这个问题，看来一直没有解决。

是个bug，非常影响使用。曾经反馈给uos技术，没有解决这个问题。

而且对方立刻就复现出来了，一个笔记本加外接一个显示器即可

• 是什么机器型号呢，麻烦上传一下设备信息，我们定位看看
• 我们测试环境的机器试了一下这个问题，暂时没复现出来~

• 这个问题在V20.5版本的时候我们已经提交过问题单（4月2号），在后面的20.6， 20.7版本中研发发现问题消失，问题也一直被挂起在；
• 目前之前能复现的设备也无法复现该问题了；
• 可以终端执行下这行命令，提供一下输出的系统信息截图：sudo apt install inxi -y && inxi -F && cat /etc/apt/sources.list /etc/apt/sources.list.d/*.list |grep -v ^#

• 提供一下上面执行的截图信息，看我们是否能找到相关设备再尝试复现。

啊，我当时两台笔记本都是这样，一个uos，一个deepin，都是最新版本，用的是小米redmi 27寸的显示屏，HDMI插口。OS: Deepin 20.7.1 x86_64，uos是21.3.1 x86_64版本。

关键是测试的时候，你把HDMI插口插上外接的显示屏幕以后，然后把笔记本盒盖，外接显示屏就黑屏了，哪怕设置笔记本盒盖，无任何操作。我联系过uos的技术，对方很快就复现出来了。我可以一会儿再去确认下。

稍等，我一会儿再确认下

• 用5.18.17内核试试呢~

怎么使用5.18.17内核？

旧的笔记本开机进入的时候，开了几次机，要么大屏幕花屏，但是貌似盒盖，外接大屏幕不会关闭，只是花屏，要么外接大屏幕干脆黑屏

• 试试这个：sudo apt install linux-image-deepin-hwe-amd64 linux-headers-deepin-hwe-amd64
• 你那个还是5.10的内核，在4月份的时候这个问题就有发现了，试试新版本内核看看。

好的，我看一下。但是我的旧笔记本电脑是deepin，新笔记本电脑是uos，deepin花屏或者黑屏，uos笔记本这种现象100%，uos也是一样装新的内核吗？

• 亲您在终端试试升级最新内核看看
• sudo apt install linux-image-5.18.17-amd64-desktop-hwe linux-headers-5.18.17-amd64-desktop-hwe

deepin旧电脑升级内核没有问题，uos新电脑无法升级，没有找到软件包

但是deepin旧电脑现在连接hdmi外接屏幕是黑屏状态，都无法显示屏幕，uos新电脑才是问题问题复现100%

现在可以把旧电脑deepin外接屏幕黑屏解决吗？uos新电脑估计要等他们把新内核弄上去才能测试了，或者uos有啥简单办法吗

谢谢啦，已经解决

1，旧笔记本deepin升级到5.18内核就没问题了

2，新笔记本uos还没5.18内核，就等5.18内核吧
