I don’t know why this was so hard. Lots of hacks out there for getting dual head working on an ATI Radeon. This is an X1300.
I started up and Ubuntu detected that there was a Radeon installed and the restricted drivers manager wanted to install the fglrx (ati) drivers. I did this and rebooted, then ran this command with a fairly clean xorg.conf:
aticonfig –initial=dual-head –dtop=horizontal
So that’s all you did, and it worked? Sweet, I’ll give it a try. I’ve been messing around with a lot more options and they keep breaking my config.
Yeah it worked alright. Trying to use compiz and all that crap proved harder but I decided it wasn’t really necessary and got back to work.
Recently when installing some updates on ubuntu hardy, graphics got real slow, it looked like compiz enabled itself, and I was seeing some visual distortion. ‘fglrxinfo’ was reporting then OpenGL vendor as Mesa not ATI, and I found the answer here. Running ‘sudo apt-get remove xserver-xgl’ returned life to normal.
