我希望非lts版本成为默认版本,因此我不需要转到高级选项并在打开计算机时选择最新版本。你能帮助我吗?谢谢。
答案 0 :(得分:3)
您可以使用Grub Customizer设置默认启动项。 通过运行
安装Grub Customizer# pacman -S grub-customizer
然后打开它。转到“常规设置”选项卡并设置默认条目。
答案 1 :(得分:1)
在此之前,请确保您可以恢复到当前状态,以防此尝试失败。
在你的grub.cfg中,以“menuentry'Arch Linux'”开头的部分是指向默认内核的部分。为了指出你选择的内核:
将以“linux / boot / vmlinuz-linux-lts ...”开头的条目更改为您的自定义内核映像(例如“linux / boot / vmlinuz-linux root = UUID = 8fb68a6d-5088-47dc- 8f9a-63e21ae275d4 rw quiet“在同一个grub.cfg文件中)
将条目“initrd /boot/initramfs-linux-lts.img”更改为与自定义内核对应的initramfs。
我猜你已经有了自定义内核和相应的initramfs。您始终可以通过运行# mkinitcpio -g /boot/mycustominitramfs -k /boot/mycustomkernelimage
答案 2 :(得分:0)

/etc/default/grub
以选择您喜欢的默认菜单项。您可以通过GRUB条目列表中的索引或上一条命令中显示的名称来引用菜单条目。# GRUB_DEFAULT=0 # default/first menu entry
GRUB_DEFAULT='Advanced options for Arch Linux>Arch Linux, with Linux linux-ck-skylake' # your new choice
请注意,您可以使用>
个字符访问子菜单条目,例如({<1>的输出中显示的第一个子菜单为0>1
。有关更多详细信息,请参见下面的Wiki条目。)显然,我的输入是在“高级选项”下。
$ sudo grub-mkconfig -o /boot/grub/grub.cfg
