本文详细指导如何在Deepin 20.2 Linux中修改grub配置文件，实现不同内核版本的启动选择，并设置自定义的图形模式。适合对Grub配置不熟悉但需要管理启动项的用户。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

网上试了很多乱七八糟的都不管用,最后摸索的方法如下:

以管理员权限打开/boot/grub/grub.cfg

找到### BEGIN /etc/grub.d/10_linux ###位置

### BEGIN /etc/grub.d/10_linux ###
function gfxmode {
	set gfxpayload="${1}"
}
set linux_gfx_mode=
export linux_gfx_mode
menuentry 'Deepin 20.2 GNU/Linux' --class deepin --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-7dbd1c36-9f2f-497f-9ae0-e91a49f36073' {
	load_video
	insmod gzio
	if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
	insmod part_gpt
	insmod ext2
	set root='hd0,gpt2'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2  4b2b5dfd-c487-45df-b5c8-2054a72e03f2

		boot 
	}
}

### END /etc/grub.d/10_linux ###

把第一个menuentry里面的(用下面submenu里面的)

	linux	/vmlinuz-5.4.50-amd64-desktop root=/dev/mapper/vg0-Roota ro  splash quiet DEEPIN_GFXMODE=$DEEPIN_GFXMODE
	initrd	/initrd.img-5.4.50-amd64-desktop

替换为你想要默认启动的
