Trouble installing additional driver
Perhaps you can try installing the newest ATI fglrx drivers manually. The following website is an unofficial wiki for ATI drivers. I am using Radeon 5650, and Catalyst 12.1 on Ubuntu 11.10. Unity 3D works smooth.
The CPU fan isn't that over-loaded compared with no GPU installed, according to my own experience.
This link is from the official ATI catalyst page.
Hit the link Unofficial Wiki for the AMD Linux Driver to get you there. The wiki page contains step-by-step instructions for Linux installation.
When presented the additional driver options in the GUI jockey interface, do you have 2 options?
- ATI/AMD proprietary graphics driver (post-release updates)
- ATI/AMD proprietary graphics driver
so, if you're trying option 1 it will not work as the bug above shows. option 2 installs. And it uses the fglrx driver for the ATI card, but usability and control center is absent for me until aticongfig is run. That however crashes everything. An option is to continue the use of radeon open source driver. https://help.ubuntu.com/community/RadeonDriver
