Comment 3 for bug 576843

Further to the above ... I don't know any more about the immediate-restart thing, but other standby and hibernate problems have been solved by switching to uswsusp.

1. Use synaptic package manager (on the System/Administration menu) to install uswsusp#

2. Use terminal (on the Applications/Accessories menu) to try it, by typing
          sudo s2disk
    for hibernation or
          sudo s2ram
    for suspend.

3. If one or both of these works, you can make this the default system for hibernate and suspend by typing
          sudo gedit /etc/pm/config.d/00sleep_module
    then editing the last line to read
          SLEEP_MODULE="uswsusp"
    (with no hash # symbol)
    and don't forget to save before closing

4. Tweaking instructions (if required) are here: http://wiki.opensuse.org/SDB:Suspend_to_RAM
    Look for the ones for your video card, if listed.
    Not sure whether point 3 above can be made to work if you need tweaks.
