    Default SUSE X64, 12.1 does not wakeup after s2ram

    Hi,

    I have a desktop computer with 16 GB memory, 2 TB hard disk with dual boot os windows 7 and SUSE 12.1 X64. Graphics chip is: Radeon™ HD 6550D processor-integrated graphics (Dual monitor capable).
    I found that SUSE cannot wake up after "sleep" option within "leave" selection. I remember that the keyboard did not respond and there were three lines at the screen. The last line is something like: turn off framebuffer(?) to debug.

    When boot screen shows up, at the option line, it is:
    VGA=0x345

    After I added apm=off to the above option line, there is nothing shown on the screen now.

    I have these information after run "su" as an admin.

    Sorry, I forget to add that it has KDE. The SUSE 12.1 is new installation.

    Hi,

    From the following of Wiki s2ram, (boot from init=/bin/bash)

    Code:
    If none of the methods described here seem to work, it is important to check if the machine is completely dead on resume or only the video is not resumed properly. A good way to check this is to start with a minimal system (init=/bin/bash), run s2ram -f, and after resume, when the display is still off, check if the "Caps Lock" key still works (you should see a reaction of the Caps Lock LED on the keyboard). If it does, it is most likely really a video initialization problem. If it doesn't, then it is most likely a BIOS problem or a bug in the Linux kernel.
    I find that the computer is still live (with 's2ram -f', the computer not real sleep from my observation.) It has the message:

    Code:
    switching from vt1 to vt1...succeed.
    /sys/power/state/ does not exist, what kind of ninja mutant 
    switching back vt1 to vt1...succeed.
    What next I can do to solve the sleep problem? Thanks

    I have further test after init=/bin/bash boot.
    ..............
    mount /proc [echo: already mounted]
    mount /sys
    s2ram -f
    .............
    Then, computer sleeps, but screen and keyboard have no response anymore. what else can I do to make it s2ram succeed? Thanks.
