    It seems to be a reported problem with the nouveau video kernel driver. I think your options are the following:

    1) Switch to the nVIDIA proprietary video driver:

    Installing the nVIDIA Video Driver the Hard Way - Blogs - openSUSE Forums

    LNVHW - Load NVIDIA (driver the) Hard Way from runlevel 3 - Version 1.46 - Blogs - openSUSE Forums

    2) Upgrade to a newer kernel like 3.5.3 for instance:

    S.A.K.C. - SUSE Automated Kernel Compiler - Version 2.76 - Blogs - openSUSE Forums

    S.G.T.B. - SuSE Git Kernel Tarball Creator - Version 1.81 - Blogs - openSUSE Forums

    S.A.K.R. - SUSE Automated Kernel Remover - Version 1.0.2 - Blogs - openSUSE Forums

    Just a few bash script links that might help.

    Thank You,
