我已经使用 ppa 在 Ubuntu 中安装了 Cinnamon。我遇到的问题是新安装的 GTK 主题不会在主题应用程序中显示预览。这是屏幕截图。
正如您所看到的，窗口边框和控件预览是空白的。我该如何解决？但是，像 Mint-x 这样的默认主题会显示预览。

迟到的答案，但我希望它仍然有用。发生这种情况很可能是因为没有为 cinnamon 提供主题缩略图。看/usr/share/cinnamon/thumbnails/gtk-3.0/README：
HOW TO MAKE A GTK THEME THUMBNAIL?
----------------------------------
- Install ImageMagick ("apt install imagemagick")
- Open a terminal and run "cinnamon-preview-gtk-theme mytheme" (where mytheme is the name of the Theme you want to thumbnail)
- Press Alt+Print-Screen to take a screenshot of the window
- Go to your Pictures directory and move the screenshot to ~/screenshot.png
- Open a terminal and type:
cd
convert screenshot.png -gravity north-west -extent 120x35 thumbnail.png
WHICH THUMBNAIL IS USED BY CINNAMON TO REPRESENT A THEME?
---------------------------------------------------------
- Cinnamon first tries to find a gtk-3.0/thumbnail.png file in the theme directory
- If it doesn't find any, it looks in /usr/share/cinnamon/thumbnails/gtk-3.0/
和/usr/share/cinnamon/thumbnails/metacity-1/README：
HOW TO MAKE A METACITY THUMBNAIL?
---------------------------------
- Install ImageMagick ("apt install imagemagick")
- Open a window (Nemo for instance)
- Press Alt+Print-Screen to take a screenshot of the window
- Go to your Pictures directory and move the screenshot to ~/screenshot.png
- Open a terminal and type:
cd
convert screenshot.png -gravity north-east -extent 100x32 thumbnail.png
WHICH THUMBNAIL IS USED BY CINNAMON TO REPRESENT A THEME?
---------------------------------------------------------
- Cinnamon first tries to find a metacity-1/thumbnail.png file in the theme directory
- If it doesn't find any, it looks in /usr/share/cinnamon/thumbnails/metacity-1/
