I have recently have upgraded to Ubuntu 11.10 and I have not been able to activate by ATI Radeon Mobility HD5400 driver. I have been able to activate the ATI/AMD propreitary FGLRX graphics driver using the AMD wiki, but I cannot activate the (post-release update) driver. When I try to install through the additional driver's utility I get
Sorry, installation of this driver failed.
Please have a look at the log file for details: /var/log/jockey.log
I have looked all over the internet and almost everyone says to use the command
sudo apt-get install fglrx-updates fglrx-amdcccle-updates
When I use this though, my driver is no longer recognized as being active and I am back to square one. Does anyone know what to do?
