[arch-general] Screen goes black after installing latest nvidia driver

Today I updated my desktop which installed latest nvidia - version 260.19.12. When I tried startx, screen went black and the led of the power button of the monitor kept flashing.After I downgraded the nvidia, everything went allright. To be absolutely sure that it is not caused by anything in my system, i installed arch again on to a new partition and installed the packages. Same results. I searched the bug tracker but found nothing.Is anybody experiencing the same thing ? My system: Vga:VGA compatible controller: nVidia Corporation G86 [GeForce 8400 GS] (rev a1)
