解决方法：cd /usr/share/ati/
sudo sh ./fglrx-uninstall.sh --force
重装附加驱动：
sudo apt-get install aptitude
然后在系统设置里的附加驱动里激活第二个~~
慎重提醒：
决定升级的童鞋，升级前请将原显卡驱动卸载，升级后再重装~
升级后在附加驱动里激活：ATI/AMD 专有的 FGLRX 图形驱动
千万不要激活ATI/AMD proprietary FGLRX graphics driver (post-release updates)
原问题：用11.04直接升级11.10的~
升级后3d开不成，卸载原附加显卡驱动后，安装了amd网上的ati-driver-installer-11-8-x86.x86_64.run，结果是开关机进度条有变化是正常，其他就与没安装驱动一样，打开AMD Catalyst Control Center时：
There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following.
No AMD graphics driver is installed, or the AMD driver is not functioning properly.
Please install the AMD driver appropriate for you AMD hardware, or configure using aticonfig.
于是想彻底卸载之~~结果：
终端输入：
cd /usr/share/ati/
sudo sh ./fglrx-uninstall.sh
./fglrx-uninstall.sh: 32: cannot create /etc/ati/fglrx-uninstall.log: Directory nonexistent
[Warning] Uninstall : inst_path_default or inst_path_override
does not exist in /etc/ati. This suggests that the AMD driver
is not installed, the AMD driver is only partially installed,
or the current AMD driver installed is an older version than the
one this script was designed for. Both files listed above are
required for determining where installed files are located.
To force uninstallation of the driver by guessing where the
uninstallation files are located, set the force option
re-run ./fglrx-uninstall.sh (this is not recommended).
彻底无语了，纠结了几天才上来发帖，更新真是错误~
