看起来您缺少 Yaru 主题。您可以使用以下方法获得与普通桌面略微接近的外观:
sudo apt install yaru-theme-unity yaru-theme-gtk yaru-theme-icon yaru-theme-sound
有许多 Yaru 主题包可用,你可以在 apt 中找到它们,如下所示:
sudo apt search yaru
这会给你类似这样的结果:
yaru-theme-gnome-shell/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
Yaru GNOME Shell desktop theme from the Ubuntu Community
yaru-theme-gtk/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
Yaru GTK theme from the Ubuntu Community
yaru-theme-icon/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
Yaru icon theme from the Ubuntu Community
yaru-theme-sound/focal-updates,focal-updates,now 20.04.11.1 all [installed,automatic]
Yaru sound theme from the Ubuntu Community
yaru-theme-unity/focal-updates,focal-updates 20.04.11.1 all
Yaru Unity theme from the Ubuntu Community
笔记:以上输出来自 20.04 LTS 桌面安装。由于您已安装 Unity 主题,因此apt
此答案中的第一个命令将替换yaru-theme-gnome-shell
为yaru-theme-unity
。
