您好，我想知道您是否可以帮助我处理我的 grub 菜单；我无法在 HDMI 显示器上看到它，因此我最终只能启动默认选项，除非我记得如何盲目驱动它。我的显示器是华硕 PB278Q 到华硕Z97M-PLUS主板。
我安装了 3 个操作系统：Ubuntu Studio 19.10、Xubuntu 19.10 和 Linux Mint 19.3。
inxi -Q 报告：
Graphics: Device-1: Intel Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics driver: i915 v: kernel
Display: x11 server: X.Org 1.20.5 driver: modesetting unloaded: fbdev,vesa resolution: 2560x1440~60Hz
OpenGL: renderer: Mesa DRI Intel Haswell Desktop v: 4.5 Mesa 19.2.8
这是 xrandr -q 的输出：
Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 16384 x 16384
VGA-1 disconnected (normal left inverted right x axis y axis)

这是我当前的 /etc/default/grub

上面当前的视频选择来自 shell 脚本 for 循环，位于
它报告了有关我的系统的信息：
HDMI-A-1: disconnected
HDMI-A-2: connected
VGA-1: disconnected
我相信几周前我确实在 HDMI 显示器上看到了菜单两次。那是在我开始尝试编辑 /etc/default/grub 之前很久。
任何想法表示赞赏。
谢谢
