  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:
  ASUS F8Vr;Intel Core Duo T8300;ATI Mobility Radeon HD 3470;VRAM:256MB;14"WXGA
  1.需要解决的问题:
  (1)安装驱动后开机和关机画面花屏,分辨率低;
  (2)开机画面直接出现,一闪而过,错过点点进度过程。
  2.解决 方案:uvesafb 替代 vesafb
  3.所需包:
  (1)v86d(uvesafb需要)
  (2)hwinfo(查看framebuffer)
  4.解决步骤:
  (1)安装驱动
  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=""

  # This works with Linux (no patch required) and with any kernel that obtains
  # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

  # 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=1024x768
  # 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_LINUX_RECOVERY="true"
  # Uncomment to get a beep at grub start
