我遇到了一个问题。我尝试使用 ubuntu-frame 在 ubuntu-core 中运行我的应用程序。但在某些情况下，我的屏幕出现了问题。
我的环境是：一台普通的PC，Ubuntu core 22，显卡是Nvidia 1050ti
我安装的快照：

我使用两个屏幕，可以随时添加另一个。我在 ubuntu frame 中的视频配置如下：
$ snap get ubuntu-frame display

我每天都使用external布局。当我打开带有两个显示器的 PC 时，它工作正常，但如果此时我连接一个新显示器（作为第三个显示器），此屏幕不会显示任何内容（只有带有闪烁下划线的黑屏）。为了解决这个问题，我必须重新启动 ubuntu-frame 服务。
我的目标是随时连接第三台显示器，但避免重新启动 ubuntu-frame，因为如果我重新启动 ubuntu-frame，它也会重新启动我正在运行的应用程序。
我一直在测试另一种方法来消除我的疑虑，使用 ubuntu-server 和 X11，我可以连接第三台显示器并运行 xrandr -d :0 --output HDMI-A-1 --mode 1920x1080，之后显示器可以正确显示我的应用程序，无需重新启动 X11 即可“更新我的更改”（xrand 更改）
在 ubuntu-core 中使用 ubuntu-frame 进行另一项测试，并使用“默认”布局，我连接了 2 个显示器，启动了我的 PC，它运行正常，但是当我连接我的第 3 个显示器并修复配置以ubuntu-frame set ...设置我的“外部”布局并配置这个新显示器时，它不起作用。此时在日志中看不到任何内容。
$ sudo journalctl -f

但是，如果我重新启动 ubuntu-frame，当然重新启动我的所有应用程序（这对我来说是一个问题），我会看到如何在日志中更改应用程序。
