我有一个包含 Windows 10 和 Ubuntu Mate 的 UEFI 双引导系统。 Ubuntu Mate 安装已设置 Grub 用于选择操作系统。现在我想更改默认的 Grub 主题。
这是我所做的步骤：
1. Get theme archive: wget https://github.com/shvchk/poly-light/archive/master.zip
2. Unpack theme: unzip master.zip
3. Remove theme archive: rm master.zip
4. Create GRUB themes directory: sudo mkdir -p /boot/grub/themes
5. Move theme to GRUB themes directory: sudo mv poly-light-master /boot/grub/themes/poly-light
6. Set GRUB_THEME=/boot/grub/themes/poly-light/theme.txt in GRUB config: sudo nano /etc/default/grub
7. Update GRUB: sudo update-grub
但我在启动时看到 Ubuntu 安装的默认主题？！我可以做什么来正确更改主题？
我的 GRUB 配置（/etc/default/grub/）：
# 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="saved"
#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 intel_idle.max_cstate=1"
GRUB_CMDLINE_LINUX=""
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
# 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_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
GRUB_SAVEDEFAULT="true"
GRUB_THEME="/boot/grub/themes/poly-light/theme.txt"
export GRUB_COLOR_NORMAL="light-gray/black"
export GRUB_COLOR_HIGHLIGHT="magenta/black"
谢谢
