Hi folks, in earlier times suspend-to-disk worked fine, but now after the years things changed. Suspend-to-disk is no more working. This might be by changes in the kernel and in the packages. So I want to do a fresh configuration for susspending. What packages do I really need? On my debian/testing I have laptop-mode-tools, uswsusp, tux-on-ice, powerdevil (Plasma5),acpi and hibernate. I believe, these might be too much. Any ideas? Thanks for any hints. Best Hans I believe nowadays suspend\hibernate functions are handled purely
by kernel, which talks directly with ACPI firmware of the
motherboard. So you don't need any additional (legacy) packages to
get that functionality, besides systemd that has modules to help
handle sleep\suspend\hibernation functionality. This is how
hibernation works on my PC workstation and on my cheap netbook. There are wiki page that helps with configuration and explains
many things about how hibernation works. [1] Basically all you
have to do is create a large enough swap partition and setup it's
GUID in "resume" file located inside "/etc/initramfs-tools/conf.d"
folder. Also, it might be helpful to check out kernel documentation about these functions and how to test and debug them. [2] [1] https://wiki.debian.org/Hibernation [2]
