    Looks like this:

    So try to add "nomodeset" to the boot options (in YaST->System->Boot Loader->Boot Loader Options f.e.) and see if it works then.
    If I understand the bug report right, your system is only able to use the "mga" driver when nomodeset is specified.

    Thank you for your reply

    in my boot option i got this :

    VGA MODE: unspecified
    optional kernel command line parameter : resume=/dev/disk/by-id/scsi-3600605b006daef701a5f0b2125a4efbb-part2 splash=silent quiet showopts

    failsafe kernel command line parameter : showopts apm=off noresume edd=off powersaved=off nohz=off highres=off processor.max_cstate=1 nomodeset x11failsafe


    is this mean nomodset is already there?

    Well, yes and no.

    The second line is for "recovery mode" (you can select that under "Advanced Options" in the boot menu).
    But you should try to add "nomodeset" to the first one as well, i.e. "Optional Kernel Command Line Parameter".
