Ubuntu 10.10 安装ATI显卡后开机分辨率低的完美解决[图文]

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 vesafb3.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framebuffersudo hwinfo –framebuffer

我的显示器分辨率是1024×768的所以我需要的是：1024×768-24（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.
