ubuntu 12.10 显卡问题和解决 Failed to build fglrx-8.961 with DKMS

引用:
显示芯片: AMD Radeon HD （6470M+ 6380G）双显卡切换

显卡描述: 独立显卡

显卡厂商: AMD

默认安装是好的可以unity-3d。

后来我安装了个显卡驱动反而只能进unity-2d了，驱动安装出现问题日志如下：

代码:
$cat /usr/share/ati/fglrx-install.log

代码:

这里的方法果然好使我现在又回到默认(也就是木装显卡驱动之前)uniy-3d的界面了

我是amd64的（32的看上面链接里面提供的方法）

代码:

$ sudo sh /usr/share/ati/fglrx-uninstall.sh

$ sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

$ sudo rm /etc/X11/xorg.conf

$ sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core

$ sudo dpkg-reconfigure xserver-xorg

$ sudo reboot

以上回复桌面方式对12.04同样有效

2014-02-08今天升级12.04 到13.10，但是升级失败，然后回退，但是需要重新安装显卡驱动。但是遇到重装之后只能现实命令行模式，无法进入图形界面，卸载显卡驱动可以进入。

在不选择冲撞系统的前提下，反复折腾，最后在附加驱动里安装了一个，然后在更新管理器中更新了一个相应的补丁。ok，重启，进入系统。虽然这个驱动略显粗糙，但是开发完全够，避免了重装系统的代价。
