Getting Dual screen setups to work with ATI Radeon Cards and (K)Ubuntu Gutsy Gibbon
This was quite the sore topic for me, which has turned me off of ATI once and for all. But I got it working and wanted to share my findings with the community
So . . .
What I did, was to download the driver from ATI. Then build a package for gutsy (I renamed the download because it was too long to type and I am lazy):
You're not done yet. The above will install the xorg driver, but not the kernel module. It seems that I had to do that myself. This is contained in the fglrx-kernel-source package that you installed above.
cd into /usr/src, and run
sudo tar xvfj fglrx.tar.bz2
This will create a modules directory. cd into modules/fglrx and run the make.sh. this will build the fglrx kernel module.
cd /usr/src/modules
sudo ./make.sh
If all is built well, you should have a module called fglrx.ko. Copy this into /lib/modules/<your kernel version>/volatile/.
