Recently installed Xubuntu 18.04 LTS(bionic beaver) as dual boot alongside Windows 10 on my Dell laptop. Neither hibernation nor suspend is working. When I close the lid of my computer and open it again I get a black screen. Machine seems to be running but I get no response. Only option is to hit the shutdown button to force shutdown.
Since I did not create a swap partition on installation, I used a live cd to resize my Ubuntu partition and create a swap partition. I also hit the swapon option in Gparted.
Rebooted the computer back into Xubntu but still no go... same problem with suspend and hibernate.
I've looked at this answer to edit /etc/fstab but I'm not sure if that's the right thing to do.
here's how my/etc/stab file looks like:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda7 during installation
UUID=7adff708-01f9-4897-92e9-647aae470f4f / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=3E4C-F177 /boot/efi vfat umask=0077 0 1 /swapfile none swap sw 0 0
