    Question inspiron 3521 hibernate problem

    Hi everyone;

    I recently bought a Dell Inspiron 3521 laptop. It came with a 12.04 ubuntu installation. I really don't like unity, so I set up Xubuntu 12.04 with my existing iso. But after a few days i realized my OS is 32bit and laptop is 64bit. And there were some stability problems. Then I decided to go back to original system and install xubuntu-desktop on it. I did exactly like this. Now almost everything is ok, but hibernate is not working. In 32bit xubuntu installation it was working, but now is not. My system is completely up to date. I've been searching for a few days, but couldn't find something useful/working. Is anybody can help me? Thanks a lot.

    Hello and welcome to the forums.

    How are hibernating the laptop? (Hibernation is disabled by default in 12.04 - see: http://askubuntu.com/questions/94754...le-hibernation)

    Can you post back the contents of your /var/log/pm-suspend.log file like this (from a terminal window):
    Code:
    pastebinit /var/log/pm-suspend.log
    ...and post back the link that is generated.

    I'm willing to bet that zram is interfering with your hibernate attempt. Did you install zram purposefully?

    What does:
    Code:
    cat /var/log/syslog | grep PM:
    ...return?

    And oh, hibernate will also not work if you have an encrypted swap file. See: https://wiki.ubuntu.com/DebuggingKer...encrypted_swap.

    There is a potential way to make it work though, see: https://help.ubuntu.com/community/En...hEncryptedSwap

    Code:
    cat /var/log/syslog | grep PM:
    gives this: http://paste.ubuntu.com/1690746/

    i've never heard about zram nor encrypted swap :/ i'm looking at the links you gave right now.

    Re: inspiron 3521 hibernate problem

    i followed this quote, in this page, which is originally from this page. first not worked, but then i installed zram-config, restarted, than it worked.

    Making the swap partition work for hibernate (optional)
    'INFO: This will not work for 12.04, resume from hibernate work differently in 12.04.'

    1. Pull up a Terminal again and run cat /proc/swaps and hopefully you see the path to your swap partition listed there. If not chances are something went wrong in the steps above. Here's my output:


    Filename Type Size Used Priority /dev/sda2 partition 2676732 73380 -1
    1. gksu gedit /etc/default/grub & to pull up the boot loader configuration
    2. Look for the line GRUB_CMDLINE_LINUX="" and make sure it looks like this (using your UUID of course) GRUB_CMDLINE_LINUX="resume=UUID=41e86209-3802-424b-9a9d-d7683142dab7" and save the file
    3. sudo update-grub and wait for it to finish
    4. gksu gedit /etc/initramfs-tools/conf.d/resume & and make sure its contents are resume=UUID=41e86209-3802-424b-9a9d-d7683142dab7 (with your UUID of course in place of mine). Save the file!
    5. sudo update-initramfs -u
    6. Reboot!

    Now you should be able to hibernate and resume!
    now system says something like "failed to thow: -error 19" just before hibernating but it can wake up anyway. it seems ok for now. on the other hand, when i try to start zram-config in terminal, it gives this error message:

    start: Rejected send message, 1 matched rules; type="method_call", sender=":1.89" (uid=1001 pid=4087 comm="start zram-config ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")
    i'm not sure it's a problem or not

    finally, i'm not sure if it's okay to ask here, but, booting my laptop lasts exactly 45 seconds, from power button to login screen. then it takes another 20 seconds after login screen. is it normal for a new system, it seems a bit long for me.

    EDIT: i haven't seen your last post, sorry. this is the new log file: http://paste.ubuntu.com/1691744/
