How do i Kill my ATI driver?

[mylo9000]

Sorry if this is a repeat thread, but i've searched the forum and had no success finding a resolution to my issue.

Here's the story.

I setup my father with SuSE 10.2 x86_64 on his AMD Athalon 64 system
his video card is an ATI 9600 All-in-Wonder.
All his apps are setup and ok so i thought i'd tackle the video card.

following the steps on the OpenSuse.org web site all seemd to be going well.. all up until i went to test the driver. it OpenGL Vendor String showed Mesa so i tried the trouble shooting steps. now i'm stuck in terminal. every time i try to run sax2 the monitor goes out of range. ok.. not entirely.. if i run sax2 -r -l -m 0=vesa i will load but the samsung lcd monitor can't adjust to center the image on screen.

i checked around and i can't find this automated uninstall sh that is supposed to be part of the ati driver package. nor can i figure out how to restore the video back to what it was when i first installed Suse.

it took quite some time to configure and setup all the apps on this system so i really don't want to frag it all and start over.

does anyone have any ideas on how to get this working again? even if i have to go back to the generic 2d driver?

From ATI's own documentation:

Un-installing the ATI Linux Proprietary Driver is dependent on the mode of initial installation.
Automatic or Custom Driver Installations

If the ATI Proprietary Linux Graphics Driver was installed using either the Automatic or Custom options, then do the following:

1. Launch the Terminal Application/Window and navigate to the /usr/share/ati folder.
2. With super user permissions, enter the command "sh ./fglrx-uninstall.sh"

You have now successfully uninstalled the ATI Linux Proprietary Graphics Driver.

nor can i figure out how to restore the video back to what it was when i first installed Suse.

You can simply edit the file /etc/X11/xorg.conf and tell the X server to use the free radeon driver instead of the fglrx one (ATI proprietary).

So you should have a line like that:

Driver		"fglrx"

change it to:

Driver		"radeon"

it took quite some time to configure and setup all the apps on this system so i really don't want to frag it all and start over.

But you did figure it out, so next time it'll certainly be a lot quicker.

There even is section about ATI drivers, using pre-build packages, so a lot easier to set up.
