在UEFI BIOS模式下GRUB缓慢/无响应

I have a GTX 1060 GPU, a ultrawide (21:9) 2560x1080 monitor and a MSI B-450 A PRO motherboard (bios version V10.C - 2019/11/12).

最近,我将BIOS的启动模式从CSM更改为UEFI。 此后,我的grub开始使用显示器分辨率(2560x1080),然后才仅支持不超过1920x1080。

进行此更改后,grub的速度非常慢,达到了我可以看到屏幕呈现蜂鸣的程度,并且我必须注意不要在grub外壳中键入太快(甚至不是中等速度),否则会错过按键操作。

我的/ etc / default / grub具有以下内容:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

有谁知道发生了什么,以及如何解决?
