    Working fine on a Compal HL-90.

    Not working fine on an ancient ASUS laptop since I don't get the screen back when it wakes up.. then again I got the same problem after logging out, so not related

    I usually find suspend to disk to be ok. Works on most everything I
    tried. My tests usually involve network, video and dvd video at
    the same time... occasionally I'll through in an OpenGL game too...
    all at the same time.

    Suspend to ram... that's different. There's a lot of variables
    especially with drivers.... I find this one usually does not work
    for (except on a minority of cases).

    I find that for suspend to ram, that using the open source drivers
    with a radeon card.. works pretty well. Nvidia is a mixed bag and
    so is Intel (oddly enough). Intel wireless is a mixed bag, newer
    chips 5xxx don't seem to work as well as the older B/G ones.

    But hey... again, there's a LOT of variables...

    But usually suspend to disk always works for me. Some laptops tested:

    Dell D600
    Dell D630 (Nvidia)
    Dell M70
    Dell M90
    Dell M6300
    (and some other older Dells)

    HP 2530p (I really like this one... small and fast)
    HP 6710w
    HP 8710w
    (and some other older HPs)

    All of the above passed my suspend to disk tests using either
    openSUSE 10.3, 11.0... 11.1 on the 2530p.

    Can't remember which of these did ok on suspend to ram (if any).

    Okay then.
    Samsung Q45, S2RAM works fine out of the box.
    Never tried S2disk on this one, because the last time I tried, it was about as slow/fast as a reboot.

    HP dv6000, never ever seen suspend to RAM working .

    It suspends ok (I think), as the suspend light flashes, but on resume all I get are the lights and fan coming on. All else is dead .

    I always use the non-free nvidia driver if that makes a difference.

    This is my current "project", so if anyone has any ideas please fire away .

    Suspend to disk works, but is (in my opinion) completely useless as it (as Uwe said) mostly slower than a normal shutdown and boot.

    It very likely does, as their binary drivers supported "Suspend to Disk" last, and kernel hackers could do nothing to locate the cause.

    At one time, it was possible to use 2D 'nv' FOSS driver (it still works with an older card), but that didn't work so dumping my last Nvidia card was the only solution.

    Odd, I use it in openSUSE 11.0 on a couple of laptops, and I find it is
    faster than a shutdown/reboot.

    Especially since it brings back the apps in their current state
    as well. I guess if nothing is going on, it's debatable why you
    would suspend to disk in the first place.

    Booting takes less than 1:30 minutes (usually) in a worst case
    scenario (lots of drivers, etc).... is that really unacceptable?

    Why would one have to boot up faster just to put something
    incomprehensible on their facebook page?

    There's some rather entertaining stuff on cause of some problems, if you're into sordid details Guide for BIOS writers

    There's quite a lot of material pointing to anti-competitive behaviour by a well known software company, which may explain some difficulties.

    [Phoronix] Foxconn Does Hate Linux Support

    Part of the reason for this is explained well in this talkback MoBo Manufacturer Foxconn Refuses To Support Linux


    Buying hardware that supports Linux really is important, if you want to see a change in the situation. Whilst kernel hackers do their utmost, folk who think they should buy what they fancy at that moment, and then expect the OS to "just work" are really ignoring the technical reality of the situation.

    It worked on my Dell Latitude D400. I didn't notice any real gain in time to usability restoring from disk and booting up fresh.
