Dear Joseph Unfortunately, installing vmlinuz-4.19.0-041900rc2-generic with modules did not help. Both pm-suspend and pm-hibernate freeze the system - pm-hibernate succeeded partially only, i.e. the fan runs and the power led is not flashing.
By the way, I could not install the headers due to dependency problems, and I did solve them. Could I provide further information? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790606 Title: Acer Aspire ES-512 cannot hibernate/suspend on newer kernels than 3.17 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1790606/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
