文首声明,Ubuntu 10.10 安装ATI显卡后开机分辨率低的完美解决主体参照于这篇文章,只不过这篇文章应用的环境是Ubuntu 10.04 @ Nvidia显卡
我的机器配置:

(2)hwinfo(查看framebuffer)

系统-系统管理-附加驱动

(2)安装所需包:
sudo apt-get install v86d hwinfo
(3)查看framebuffer
sudo hwinfo --framebuffer

我的显示器分辨率是1024x768的所以我需要的是:1024x768-24
(4)修改grub文件(紫色是修改后的)
sudo gedit /etc/default/grub
----------------------------------------------------
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.


GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=20
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1024x768-24,mtrr=3,scroll=ywrap"
GRUB_CMDLINE_LINUX=""
