Ubuntu 9.10使用了grub2(不确定是不是2)，与以往不同新版本的grub的引导配置文件不再是menu.lst而是
/boot/grub/grub.cfg ，这个文件默认是只读的，因此在修改之前需要先将其改为可写
sudo chmod +w /boot/grub/grub.cfg
然后就可以修改了。给其中加上如下内容即可
sudo gedit /boot/grub/grub.cfg
添加后内容如下：
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by /usr/sbin/grub-mkconfig using templates
# from and settings from /etc/default/grub
#

insmod gfxterm
