装了两天,终于装好了显卡驱动,把过程最后成功的过程写在这里吧,大部分翻译自这里:

1.下载最新驱动:https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver-installer-8.30.3.run
   ps:The new fglrx driver supports Radeon 9500+ (older cards will not work!) and the X-series cards up to X1900.

2.移去所有已装驱动:
   apt-get remove --purge fglrx-control fglrx-kernel-* xorg-driver-fglrx

3.
sudo gedit /etc/X11/xorg.conf

在文件最后添加:

Section "Extensions"
        Option  "Composite" "0"
EndSection

4.禁用旧的fglrx模块

sudo gedit /etc/default/linux-restricted-modules-common

修改:
DISABLED_MODULES="fglrx"

5.cd到你所下载的驱动所在的文件夹,安装必要工具:

sudo apt-get update
sudo apt-get install module-assistant build-essential 
sudo apt-get install fakeroot dh-make debconf libstdc++5 linux-headers-$(uname -r) 
6.生成.deb包:
sudo ln -sf bash /bin/sh
bash ati-driver-installer-8.30.3.run --buildpkg Ubuntu/edgy
sudo ln -sf dash /bin/sh 
7.安装:
sudo dpkg -i xorg-driver-fglrx_8.30.3-1*.deb
sudo dpkg -i fglrx-kernel-source_8.30.3-1*.deb
sudo dpkg -i fglrx-control_8.30.3-1*.deb

8.删除旧的fglrx deb包:
sudo rm /usr/src/fglrx-kernel*.deb


9.编译模块:
sudo module-assistant prepare
sudo module-assistant update
sudo module-assistant build fglrx
sudo module-assistant install fglrx

10.更新xorg.conf文件
sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv
sudo depmod -a

11.重启
sudo shutdown -r now

12.确认成功:
$ fglrxinfo
