Ubuntu 8.04, ATI, & Big Desktop

First off, we got some new computers at work that have the ATI Radeon 2400 HD Pro video cards. I wish I would have done some research when I had the specs for the new machines because I would have found out that ATI cards don’t get along with Ubuntu, that may have saved me all this time I’ve spent fighting with them.

I cannot even begin to think of how much time I spent trying to get them to work in Ubuntu 7.10 (Gutsy). It kept telling me there was no hardware that required the restricted drivers, but this graphics card does. I tried editing the xorg.conf file based on what I was finding online and what we had on our old machines, nothing worked. I spent hours and hours looking around online but things other people said worked never did for me. I made sure I had the correct drivers installed, checked that multiple times, it was all what it should have been. I tried doing it the easy way too, by using aticonfig. But every time I tried using that it nuked the xorg.conf file and never recreated it.

Then 8.04 (Hardy) came along. I was hoping it would somehow make things magically work or, you know, at least make things a little easier. It took me about 10 minutes after installing it to get the dual monitors working properly, aticonfig actually worked in 8.04. After spending a lot of time searching around online I found this website that I used to compare the appropriate sections of the xorg.conf file to. I think I had to add a couple things although I can’t remember what. Anyway, using a combination of aticonfig and that website I got it working perfectly. I felt like an idiot though because I forgot I had to adjust the resolution so that it added the two monitors together. Once I did that it worked like a charm. So for anybody who is having issues here’s the xorg.conf file.

Update: So I had to reinstall Hardy because the panel disappeared and I couldn’t get it to come back. This time to get Big Desktop working all I did was enable to restricted driver and type

aticonfig --dtop=horizontal

and it worked perfectly after I restarted the session. I didn’t have to adjust the resolution this time or edit the xorg.conf.

If you are using 7.10 and having problems with an ATI card then I suggest trying out 8.04, it definitely made things easier for me.
