I had the same problem and I solved this way, a work around: am not sure but I think in that case swap memory should be equal to your ram size or more, I resized to to 8gb which is equal to my ram.
open terminal and do the following: sudo gedit /etc/default/grub replace the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'" With GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'" save and close then also in terminal uncomment the line #HandleLidSwitch and make sure value equal suspend (or hibernate,depend on wha you want) to look like this HandleLidSwitch=suspend you have to restart fully twice , then try. in case it didnt work out try uninstall acpi-support y typing sudo apt-get remove acpi I found the first step of the solution from this guy https://www.youtube.com/watch?v=l8xa-PkDhhk now both hibernate and suspend works !! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566302 Title: Ubuntu 16.04: Suspend freezes the system after upgrade to linux image 4.4.0-16 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
