OpenSUSE Hardware :: Installing The Property ATI Driver ?

I have a Dell Laptop Studio 1735 with an ATI Radeon HD3650 installed and OpenSuse 11.3.

The other features are:

My intention is to install the property driver as showed in the following link

Upgrading ATI driver with atiupgrade

But before, I would like to ask you few questions, because even after having read very carefully the post, I have some doubts:

1) Do I have to run the script in X or KDE?

2) Every time I updated the kernel (using the online updating for example), I understood that I must recompile the module fglrx.ko, with the script at the following address:

automatically recompile kernel modules after kernel update

Or I will get a lof of video issues. The file fglrx.ko will be created in the following path:

/lib/modules/2.6.34.7-0.5-desktop/extra/fglrx.ko

3) I must be sure that in the file /etc/X11/Xorg.conf, the parameter Driver must be setup to fglrx and not radeonhd.

Unfortunately, in my computer this file does not exist, what I found is /etc/X11/Xorg.conf.install and as I reported below there is no trace of a Driver parameter.

Code:

As you can see there is no "Driver" parameter. Is it a problem?

4) In the case something will go wrong, can I roll back to my previous driver?

5) Do I always type the command atiupgrade - - initial, the first time I perform the installation?
