ubuntu 9.10 使用了最新的grub2,启动参数好像有不少变动,虚拟机的分辨率调整:

方法1,还是原来的vga=788

编辑 /etc/default/grub ,中的GRUB_CMDLINE_LINUX=”vga=788″

保存以后运行update-grub

但是这样子会显示

vga=788 is deprecated and asks me to use “set gfxpayload=800x600x16;800×600” before the linux line.

意思就是vga参数已经是建议不要使用了,要用另外一种方法:

方法2:

编辑/boot/grub/grub.cfg

找到引导linux那几行

增加 set gfxpayload=800x600x16,注意不要带分号,如下:

### BEGIN /etc/grub.d/10_linux ###
menuentry “Ubuntu, Linux 2.6.31-14-generic-pae” {
        recordfail=1
        if [ -n ${have_grubenv} ]; then save_env recordfail; fi
        set quiet=1
        insmod ext2
        set root=(hd0,1)
        search –no-floppy –fs-uuid –set 9a441a57-5a71-4800-b46d-2e4c1cec6dee
        set gfxpayload=800x600x16
        linux   /boot/vmlinuz-2.6.31-14-generic-pae root=UUID=9a441a57-5a71-4800-b46d-2e4c1cec6dee ro   quiet splash
        initrd  /boot/initrd.img-2.6.31-14-generic-pae
}
