方法:

1.在 /etc/modprobe.d/blacklist-framebuffer.conf 里注释掉"blacklist vesafb"并添加一行 "blacklist vga16fb"

2.在 /etc/initramfs-tools/modules里添加 fbcon 和 vesafb

在终端运行 sudo update-initramfs -u -k `uname -r`

3.执行 sudo gedit /boot/grub/grub.cfg

找到linux启动项，在kernel行之前加入 set gfxpayload=1024x768x16(此处不能改)

保存文件退出重启就有效果了。
