每次我打开 gtk 应用程序时，它都会输出 css 警告（缺少假设 px 等的单位）。我可以禁用这种可怕的冗长内容吗？
例子：
$ gedit

答案1
我不确定是否还有其他人遇到这个问题，但我肯定遇到了。解决方案非常简单。
我在 Arch Linux 上运行 xfce4，使用“dusk theme”。我在 gtk.css 文件的第 72 行遇到了此错误。
通过对“find”的输出进行 grep，我找到了该文件/usr/share/themes/Xfce-dusk/gtk-3.0/gtk.css。
在第 72 行我将其改为：
"text-shadow: 1 1 white;"
到
"text-shadow: 1px 1px white;"
瞧！再也没有烦人的错误信息了！

好吧，我通常通过将 stderr 重定向到 /dev/null 来解决这个问题
gapp 2>/dev/null
另外，尝试一下选项--gtk-no-debug all
