    Re: Very Slow Shutdown With Dual Boot System (Win10 / Ubuntu 16.04)

    The full REISUB is recommended.

    Never force shutdown your system. Use Alt+SysRq R-E-I-S-U-B instead. (For newer laptops they don't bother adding the SysRq print to the key, but it's the same as the PrtScr key)
    Holding down Ctrl+Alt and SysRq (which is the Print Screen key) while slowly typing REISUB
    R-E-I-S-U-B to force shutdown
    A good way to remember it is, and S can be before E, but others should be in order

    • R: Switch the keyboard from raw mode to XLATE mode
    • E: Send the SIGTERM signal to all processes except init
    • I: Send the SIGKILL signal to all processes except init
    • S: Sync all mounted filesystems
    • U: Remount all mounted filesystems in read-only mode
    • B: Immediately reboot the system, without unmounting partitions or syncing

    Using the REISUB method shuts down the PC almost instantly. What does it mean?

    Is it killing some background process, or is it one of the other commands?

    I did find removing quiet splash on booting, seemed to let me see shutdown also. But with my SSD shutdown was very quick, only a half screen of lines showed before it was off.

    The thing is - I can't see whether it kills any background processes because the screen turns black to quickly and is then stuck in the reboot/splash (while shutting down still) screen for a long time.

    Re: Very Slow Shutdown With Dual Boot System (Win10 / Ubuntu 16.04)

    Hiya, So it's a slow shutdown in both MS windows and ubuntu , and both installed on a samsung SSD! interesting , you may want to check the S.M.A.R.T status on both SSDs.

    Is this a desktop or a laptop?

    usually, the cause would be a service, an app running in the background, or a zombie process.

    Now, does it shutdown quickly when you preform a shutdown in terminal
    $ sudo shutdown -h now

    and while you at it, Create another user account, and log into it and try to shutdown from that account. Is the shutdown still slow?!

    According to SMART, both are in "good" health.
    It's a desktop.
    Maybe, but in both cases I can't find which. On Windows all I can see is that there was an unusually slow shut down, but it doesn't specify the causing process.
    The command didn't change the shutting-down time.
    Creating a new account didn't change the shutting-down time.

    No luck, as of now, I'm afraid. Thanks for the advice, though!

    Re: Very Slow Shutdown With Dual Boot System (Win10 / Ubuntu 16.04)

    is it slow on reboot as well as shutdown ?
    you may wan to Try this, reboot and from the GNU GRUB menu, highlight the current ubuntu kernel and hit E on the line to edit it, then remove quiet splashthen hit Ctrl+X to boot with the current kernel.
    If you shut Ubuntu down now It should shows you at the end what kind of stop job slows down your shutdown procedure. if there is any!
    if there is none , then you should probably run a file system check fsck on the disk ..

    from recovery (safe) mode

    https://wiki.ubuntu.com/RecoveryMode

    drop to a root shell , and type:

    mount -o remount,rw /
    fsck -f
    mount -o remount,ro /
    sync
    reboot

    or just select fsck from the menu as shown here
