salome crash on Fedora Core 5 with NVidia Ge Force 6600LE

Good day,

    I have a weird crash of Salome on FC5. The strange thing is that I have the same OS at work and it works. I used the same instalation instructions. The only difference is the videocard. At work I have Radeon, while at home I have NVidia Ge Force 6600LE.
    The instalation went fine and, in fact, Salome does start, however when I open a model or create a new one my Fedora simply ends the session with some flickering of the screen, so I have to log in again. I checked whether I can see something in /var/log/messeges or /var/log/Xorg.0.log, but this crash is not really mentioned there (at least no explicit errors).
    I suspected that I might have problems with Open GL. But it seems that I do have GLX extension, plus I car run some Linux Open GL games. Nvidia system information also shows GLX information and does not complain.
Please tell me if you have any guesses on what can that be.

Best regards,
