启动 gnome-control-center 时出错

gnome-control-center当我尝试在 Kubuntu 19.04 上启动时出现以下错误：

$ gnome-control-center

(gnome-control-center:3239): Gtk-WARNING **: 16:12:56.364: Theme parsing error: gtk.css:68:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

(gnome-control-center:3239): Gtk-WARNING **: 16:12:56.364: Theme parsing error: gtk.css:69:35: The style property GtkButton:child-displacement-y is deprecated and shouldn't be used anymore. It will be removed in a future version
**
ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid)
Aborted (core dumped)

有什么办法可以解决这个问题吗？

答案1

您可以运行locate gtk.css并找到这些文件的位置：

然后你可以使用以下命令进行注释：

sudo sed -i -E 's~^.*child-displacement-.*$~/* \0 */~g' /usr/share/themes/Breeze/gtk-3.20/gtk.css

对我来说，我还需要运行：

sudo sed -i -E 's~^.*-GtkScrolledWindow-scrollbars-within-bevel.*$~/* \0 */~g' /usr/share/themes/Breeze/gtk-3.20/gtk.css
