Difficulty with 3d acceleration after install of 12.3

My Dell inspiron 510m worked fine in 3d through versions 11.x and up to 12.2. however since I took the plunge and updated to 12.3 it has broken so that I can't seem to find where the settings are that will successfully turn on 3d again.

Using the "SDB:Configuring Graphic Cards in OpenSuSE" I get:
Graphics hardware as - Intel 82852/ 855GM
Driver in use - i915

This is all as it was in 12.3 which worked. (yes I checked before upgrade due to fun in the past!).

The graphics all detected fine and it works at its native 1024x768 but no nice desktop desktop enhancements and no Open GL screensavers working anymore.

The Advanced tab in "Configure desktop - Workspace Appearance and Behavior - Desktop Effects" showed Compositing type set to Open GL. I tried changing it to Xrender and that didn't help. After making that change the system will not allow me to change back to Open GL (and keep it), as each time I try accepting the change it goes back to "Xrender". If I set up a new user account though it does assume OpenGL in there but again it is not working in accelerated mode.

Sax2 is no longer available to help me out with this so does any graphics guru have any idea where I go nowadays in SuSE to address problems with graphics acceleration and find settings to correctly configure it. All the references I can find seem to be for earlier versions and suggest the now deprecated and removed sax2.

I'm getting tired of the splinters in my fingers from scratching my head ! ????
