Compiz/Fusion with Ubuntu using ATI Radeon HD 2400 Pro

[DukenukemX]

I'm new to Linux and that's why I installed Ubuntu, but I can't get my ATI Radeon HD 2400 Pro installed right. I know ATI has been known to have terrible Linux support but I hope that's not that cause.

I went to ATI's website and got the latest drivers, and I'm using Ubuntu 7.10 Gutsy Gibbon. I run the package and nothing seems to install right. I also also installed the custom configuration in Unbuntu and that didn't help.

Can anyone please help me I really wanna get Compiz/Fusion working.

Did you follow the procedure on the Ubuntu community wiki? Note that different versions of Ubuntu and different versions of the ATI drivers may require slightly different processes for installation.

Good luck. If that guide doesn't work, your only recourse may be to get a cheaper Nvidia card like an 8400 or 8500.

I install Linux on another PC with a Radeon 9700 Pro. The Compiz Fusion worked just fine before I installed the updated ATI drivers. >.< Same results as the Radeon 2400 Pro.

I've followed many installation guides without any success. I've even used Envy and still nothing. The 2D on the 9700 Pro is even slow on http://www.tech-report.com.

I really wanna give linux a try but not at the cost of buying an Nvidia video card.

Since it worked before the ATI drivers, it is possible that ATI's driver is blacklisted by Compiz. It could be any number of things, but try this:
grep "WHITELIST" /usr/bin/compiz

You should see a line like WHITELIST="nvidia intel ati radeon i810". If so, that means that it may refuse to work with the ATI provided driver. To fix this, edit the file /usr/bin/compiz with an editor (e.g. nano). You'll need to be root obviously. Then add fglrx to that list so it'll look like:
WHITELIST="nvidia intel ati radeon i810 fglrx"

Then try it again. This was from the Ubuntu Guide section on "ATI users and Compiz"

There are other potential problems, too. You said you installed both the manual install ATI provided package AND the Ubuntu repository package from restricted modules. In all likelihood, they will use different kernel modules and the restricted module package version will conflict with the other one. The kernel driver may not load properly then. Also, there's a variety of Xorg settings that could be changed to the incorrect settings by combining the different install methods.

BTW, also post the output of the following two commands (just to sanity check):
grep -i "driver" /etc/X11/xorg.conf
lsmod | grep fglrx
Edit: and
glxinfo | grep rendering
