Dear all, after trying all the combinations from en.opensuse.org/S2ram, the s2ram still hang or immediately shutdown the system. But, I try to pass the acpi_osi=!Linux to the kernel, it work well! the following settings is ok for me. s2ram --force --vbe_post If you still need any further information, please contact to me. PS. I don't known how to set the gnome-power-manager to use the settings above, is there anyone can give me some advices? I only can use root to use the s2ram command to STR. Thanks PS. s2disk is ok whether or not I pass the acpi_osi=Linux to the kernel. Best Regards, Peter Chen # dmidecode 2.9 SMBIOS 2.4 present. 28 structures occupying 1179 bytes. Table at 0x7FEDF000.
