What does the output of fglrxinfo say?

I suspect that you have a mismatching version of the driver and X windows or the kernel. If you did not install it yourself using the ATI file appropriate to your hardware and software then I would suspect such a mismatch.
Installing the driver from the ATI site is fairly easy. Here is what I do:
Make a directory to use for the install.
Check the ATI site for a driver version that is correct for your processor size (32/64) and for your graphical hardware.
Download that file. It will be named <some_long_string>.run.
Move the .run file into the directory.
Start a terminal window.
In that window, cd to the directory.
Make sure that there were no complaints about the installation.
sudo sh <some_long_string>.run --keep --install
Follow the instructions in the graphic window that the installer puts up. I use the simple and automatic choices.
Wait until the installer finishes. It can take perhaps a minute or so after you answer the last question.
You can now reboot. If you get errors or warnings or screwy operation on the restart, then use a command line to execute
This will create or truncate your xorg.conf file to a minimal file so it would be wise to move your old file (if it exists) to somewhere else first, in case you need it later. I think that you need to sudo this command.
aticonfig --initial -f
If you want to see a list of compatible software for the driver, then do what I described above except change the --keep --install options to --listpkg.
The --keep option leaves behind all of the files that the installer used. This allows you to examine them if you so desire. Once you are done with them you can remove all the files in the directory without bothering the driver. Or, if you are not interested in seeing those files then you can omit the --keep option.
Once the driver is properly installed then you can install amdcccle and you should not get any complaints from it.
One thing that I learned the hard way: if you are going to change kernels (for example, due to an update), you need to uninstall the old driver first then do a driver install after the new OS is running. The installation will leave behind a file in /usr/share/ati and the file will have uninstall in its name.
