Question

几天来，我的 Visual Studio Code 无法启动。从 code --verbose 开始产生:

$ code --verbose

        Using the fallback 'C' locale.

目前，我正在通过 SNAP 在 Ubuntu 18.04.3 LTS 上安装 1.39.2。

您可以运行 locate gtk.css并找到这些文件的位置:
然后你可以使用如下命令注释掉:

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
