再谈grub2菜单隐藏的问题

升级了linux内核之后,发现grub菜单又被覆盖了,于是打开/etc/default/grub文件:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=UUID=94418005-fdde-4c50-8fc9-06aace00e102 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
注释掉GRUB_HIDDEN_TIMEOUT和,并将GRUB_HIDDEN_TIMEOUT_QUIET选项设置为false即可。
再次更新,可以使用命令:
grub2-editenv - unset menu_auto_hide
默认第一个选项:
grub2-set-default 0
grub2-reboot 0
另外,可以手工通过长按shift键获取到grub2的菜单
