Hybrid suspend is supported by the kernel since 3.6. Could this mean that KDE would only need a button for triggering it? Lukas, Dan tells me you are working on this, how is it going? Quite good, I have the patchset on my disk, going to create the review soon :) https://git.reviewboard.kde.org/r/109351/ (kdelibs) https://git.reviewboard.kde.org/r/109352/ (kde-workspace) great. Thanks for the work. Git commit a6c2fcc8581747fe4285508ed6fef25fbe28bef6 by Lukáš Tinkl. Committed on 27/03/2013 at 09:55. Pushed by lukas into branch 'KDE/4.10'. Add hybrid suspend method to libsolid REVIEW: 109351 M +7 -0 solid/solid/org.freedesktop.PowerManagement.xml M +24 -1 solid/solid/powermanagement.cpp M +11 -8 solid/solid/powermanagement.h M +1 -0 solid/solid/powermanagement_p.h http://commits.kde.org/kdelibs/a6c2fcc8581747fe4285508ed6fef25fbe28bef6 *** Bug 293699 has been marked as a duplicate of this bug. *** After upgrading to KDE 4.11.2, I'm still not seeing hybrid suspend as an option under the "K" menu or systemsettings. Is there additional GUI work required? Unfortunately, it turned out to be very problematic from the user's POV (very long resume times on most hardware) Hello Lukas, I own an Asus laptop, that I installed a proper Vertex-4 SSD into. With 4GB of memory onboard, and ~450MB/s write speeds, hibernation by itself takes maybe 3-4 seconds on kernel 3.15. This is very nice, when I plan to leave the laptop off for a long time. But the boot loader, even with instant timeout, and UEFI firmware's quick loading speed, then waiting for the kernel to initially boot and get into a state where it can resume takes about 15-20 seconds. Not terribly much shorter than a full boot but definitely nicer to have my session still going, and not lose my running programs. However, I would _love_ to be able to simply close the lid, have the 3 second write-to-disk but then stay in ram should the laptop _not_ be unused for a terribly long period of time. In short, if I walk away 5 minutes - I want instant resume. Leave laptop for the weekend? - I want my session preserved still. So to test, I've attempted to simply use systemd "systemctl suspend-hybrid" manually. For "sleep" resumes, this is all of instantaneous. But, due to sleep intercepting all keypresses, I had to let the battery finally die before testing the resume-from-hibernation aspect of the 'hybrid' command. Again, the exact same amount of time as previous hibernate resumes. 15-20 seconds. This is _entirely_ acceptable to me. Praytell, are your patches still applicable to KDE 4.13.2? Or, will(or does already) any of the v5 developments include the Hybrid Suspend option? I am desperately wanting this feature, and wonder what sort of speed issues your own testing revealed - i am not seeing them. 2 years later and we don't have any solution? Nice... I have BIOS and HDD system and I doesn't have any speed issues in using hybrid sleep. The possiblity to optionally use the hybrid-suspension was not added at all because it might be slow to some people or perhaps to those not needing/wanting it in the first place? Sound a bit Gnome to me. Just my 2c. Is there any chances for these feature? Hi, This should be re-opened, since it has not been resolved and should be implemented in the latest Plasma. Hybrid sleep works perfectly well, and KDE's UI should support it. Thanks! any news about this? For Plasma 5, see bug 358957.
