等離子多顯示器 - 面板消失

我已經使用 KDE 5.35/Plasma 5.8 和 Kubuntu 16.04 相當一段時間了，我認為這是第一個在多個顯示器上沒有問題的版本。至目前為止...

幾週以來，我一直遇到 Plasma 小部件和麵板的問題（我只有 1 個小部件 + 1 個面板）。我的預設配置是筆記型電腦（螢幕開啟），帶有擴充座+透過擴充座的顯示連接埠連接的外部顯示器。每隔幾天，我需要斷開筆記型電腦的連接，然後透過筆記型電腦的 VGA 連接埠連接投影機。然後回到我的預設配置。

這已經工作了一段時間了。但在過去的幾周里，當我將筆記型電腦連接回塢站時，小部件和麵板是不可見的。似乎 Plasma“認為”這是另一種配置，並希望將其顯示在另一個螢幕上。

很難說這種情況到底是什麼時候開始發生的。

有什麼想法如何調試問題嗎？

答案1

我發現superuser.com 上的解決方案。

這裡我引用一下上面的回答：

根據您的情況導致此問題的原因，您可以透過編輯plasma-org.kde.plasma.desktop-appletsrc檔案然後執行來修復它

kquitapp plasmashell && kstart plasmashell

我遇到的一個原因是，在連接到外部顯示器並隨後斷開連接後，多顯示器功能有時會從筆記型電腦螢幕上「丟失」任務欄（我認為這是在 Plasma 5.5 或 5.6 中）。在這種情況下，我發現問題出在工作列配置中的lastScreen 設定。要解決此問題，請在plasma-org.kde.plasma.desktop-appletsrc 中找到如下所示的文字部分：

[Containments][1]
activityId=
formfactor=2
immutability=1
lastScreen=1
location=4
plugin=org.kde.panel
wallpaperplugin=org.kde.image

（其中一些行可能會因您的配置而異。在我的配置中，此部分僅在文件中向下十幾行，但我不知道可能會發生多少變化。）

設定lastscreen=0為我解決了這個問題。我假設它0代表我的筆記型電腦螢幕，並且1是外接顯示器。
