升级到Ubutu 12.10后Unity 3D桌面未显示解决方法

现象描述：

当从Ubuntu12.04升级成12.10后，出现如下现象：

窗口无标题栏无边框
重新登录后桌面一片空白

 

解决办法：

其实是因为本机的amd独立显卡驱动未安装正确，需按如下方式

安装显卡驱动：

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy

sudo reboot

即可恢复

How To Install AMD Catalyst Legacy Drivers in Ubuntu 12.10

Latest proprietary AMD Catalyst driver version 12.9 cannot be used with Ubuntu 12.10 If you have a AMD Radeon HD 2xxx-4xxx series card.

Drivers for these cards are now available in a separate branch called legacy series. Unfortunately these legacy drivers (version 12.6) have not been updated to work with Ubuntu 12.10. Ubuntu 12.10 comes with xorg 1.13 while these drivers have support for older xorg 1.12.

So if you want to install these drivers in Ubuntu 12.10, you have to downgrade to xorg 1.12. A PPA has been provided by Tomasz Makarewicz that includes all the required packages you need to downgrade plus a fglrx-legacy package.

To install these packages, run the following commands:

sudo add-apt-repository ppa:makson96/fglrx
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install fglrx-legacy

Do note that these packages are not officially supported by Ubuntu, so use them at your own risk. If something goes wrong, you can purge the packages by running following commands:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:makson96/fglrx
