当我启动时,grub 没有显示(仅安装了 ubuntu),我希望 grub 显示一两秒(shift 似乎无法调出它)。我的主要问题是 grub 启动时进入我认为是恢复模式,我可以以自己的身份登录并启动 x,但这显然很麻烦。有人能告诉我如何解决这个问题吗?

/boot/grub/grub.cfg
不应直接编辑。相反,GRUB_TIMEOUT
可以配置如下选项/etc/default/grub
,以下是该文件的示例:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
GRUB_DEFAULT
设置默认菜单项。例如,GRUB_DEFAULT=0
突出显示第一个菜单项。1 是第二个。也许将恢复会话设置为默认会话?
在只有一个操作系统的机器上(比如您的机器),GRUB_HIDDEN_TIMEOUT=0
隐藏菜单。确保注释掉此行。如果存在多个操作系统,则忽略此设置。还要确保值GRUB_TIMEOUT
大于 0。这是默认条目自动启动前的秒数。
进行任何更改后,请/etc/default/grub
确保运行sudo update-grub
以更新您的配置。

答案2
接受的答案对我不起作用。我通过执行以下操作禁用了恢复菜单:
/etc/default/grub
使用编辑器打开
添加此行:
GRUB_RECORDFAIL_TIMEOUT=5
更新 Grub:
sudo update-grub
因此菜单仅显示 5 秒,然后启动过程继续。
