    Hi Marcus,

    A screen with blinking green blocks implies that your display is in text
    mode, not in graphics mode. I don't know what options you are using,
    but have you tried using:

    acpi_sleep=s3_mode

    If the above does not work, also try

    acpi_sleep=s3_bios,s3_mode

    If it is still not working, you can add this to your suspend script:

    vbetool vbemode set <VESA mode ID>

    where VESA mode ID = "vga=" value - 512 (0x200)

    Tony

    PS: If your BIOS setup has an option to re-POST the graphics card on
    resume, that is a big help.
