为什么我看不到使用 GRUB Customizer 更改的图像？

Question

我安装了grub-customizer编辑启动屏幕。到目前为止，它工作正常（例如超时），但有关背景图像（可能还有字体样式）的更改未应用。我将图像放在/启动. 如何改善？

Answer 1

我发现我必须根据屏幕分辨率裁剪/调整图像大小。发现类似的问题这里。

Answer 2

1. 找出你的屏幕分辨率（对于 Xubuntu，系统设置 > 显示）例如 1600x900
2. 将图片大小调整为与屏幕分辨率大小相同（我的情况是 1600x900）
3. 为了节省空间，还将图片重新格式化为 .png 格式。
4. 在 grub 定制器菜单下，选中自定义尺寸复选框并输入您的屏幕分辨率大小（与图片大小相同）例如 1600x900
5. 添加您的图片并保存。
