There's a lot of questions about suspend / resume in askubuntu.com. The root cause of the problems is too small swap file. It's only 2G by default and too small to store the RAM contents which are typically 4-16G of physical memory. Increasing the swap size to be at least equal with RAM solves the problem.
-------- NEW After the Ubuntu installation the default swapfile is only 2G in and any larger RAM cannot be saved saved when hibernating or suspending. The following commands increase the swap size to 16G which usually solves the issue: sudo swapoff sudo fallocate -l 16G /swapfile sudo swapon -------- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1804886 Title: add fix to "https://help.ubuntu.com/stable/ubuntu-help/power- suspendfail.html.en" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-docs/+bug/1804886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
