I have a new Toshiba Satellite P200 17D, with a core 2 duo processor and a 965 graphical chipset.
I have problems with 3D acceleration:
On fedora 7 (64 bits version), when I launch an app that need 3d acceleration, the X server suddenly enters on a loop, dying and restarting, and the only way to end it is by shutting down the machine the hard way.
With sabayon 3.4e (64 bits version, live dvd mode), the app starts and after five seconds the whole system freeze. Obviously, the same happens with 3d desktop, with both, xgl and aiglx (the desktop without acceleration works OK) and also here I need to shut down the system by holding the power button.
AFAIK, fedora 7 uses Xorg 7.2, and sabayon 3.4e a preview of 7.3
No error message is shown
2D graphics works OK on both.
I tried the fedora's 8 test 3 and the 3d is working there, so it seems that xorg 7.3 solves the problem
