Rotate Display & Screensaver

[Doerak]

He,
I just installed iPC OSx86 10.5.6 Universal FINAL. Thank you for the release.

I would like to have the rotate function of my display working. Normally the feature is shown in the display system preference. But not now.

Also when i use the screensaver "Flurry" is goes very shocky.

Looks like there is something with my Gfx settings?

Before iPC' s release i had zephyroth's OSx86 AMD 10.5.2 Revision 2.
The display rotation and screensaver worked fine.
When i updated zephyroth's to 10.5.3 (or 5.4 or 5.5) i couldn' t rotate anymore , and the screensaver was shocky.

I've tried to apply Gfxcard strings with OSX86Tools, but that didn't work.
My graphic card is a Nvidia 6600LE.

Any sugestions are welcome. Thank you.
