当我连接到外接显示器时无法获取双启动 grub 菜单

我使用 ubuntu 20.04 和 windows 作为双启动。每次我重新启动时，我通常都会得到双启动 grub 菜单（无需连接到外部显示器），但当我连接到外部显示器时，这种情况不会发生。我查找了同一问题的一些答案，但仍然无法找到它。这是我的 grub 文件

# 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'

GRUB_DEFAULT=on
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
