ATI Driver install error

[lignjuks]

When installing driver I get the following error:

Uninstalling any previously installed drivers.
Unloading radeon module...
Unloading drm module...
ERROR: Module drm is in use by ttm,drm_kms_helper
[Message] Kernel Module : Trying to install a precompiled kernel module.
[Message] Kernel Module : Precompiled kernel module version mismatched.
[Error] Kernel Module : Kernel module build environment not found - please consult readme.
[Reboot] Kernel Module : mkinitrd

What went wrong?

My way to start the installation was the following:

1. On the boot i am add line : nomodeset
2. After the login screen appearance i am press ctrl+alt+f1
3. Loged as root
4. Committed the command init 3
5. Then started the installation of ATI drivers

Hi,

This means you haven't installed linux-kbuild and linux-headers package for your specific kernel.

It could go like:

apt-get install linux-kbuild-3.0.0
apt-get install linux-headers-`uname -r`

If you have older kernel you might choose to install linux-kbuild-X with the proper version.
