I've been running into a consistent problem on a new 12.10 install where I can't get the proprietary drivers running for my Radeon HD 7750 graphics card. I've installed the fglrx and fglrx-updates packages through apt a number of times with no luck. Like many others with this problem, I'm able to login but I just don't get the unity interface or compiz, but I can get to terminal, etc.
I have also tried installing the 12.9, 12.10, and 12.11 beta drivers from AMD's website with no avail. However, when I run the installer for the 12.10 drivers it gives me a dialogue that says "one or more tools required for installation cannot be found on the system."
Tracing that to /usr/share/ati/fglrx-install.log gives me the following:
So I went ahead and tried to run
Supported adapter detected. check if the system has the tools required for installation.
Check if the system has the tools required for installation.
flgrx installation requires that the system have kernel headers.
/lib/modules/3.7.0-4-generic/build/include/linux/version.h cannot be found on this system.
but it tells me I"ve got the current version.
sudo apt-get install linux-headers-generic
So what is going on here? I tried forcing a reinstall of the kernel headers and I still get the same problem. Why won't the drivers recognize my headers? Is that problem even related to the unity/compiz issues on boot-up?

Thanks in advance for the help.
