This means that s2idle mode and deep mode are the two modes supported by your machine, and that deep is the mode that will be used for sleep when no specific mode is specified, such as using the lid switch or the logout menu or systemctl suspend for example. In OP's case, deep is manually set as default using the kernel parameter mem_sleep_default=deep. Generally the kernel chooses the deepest mode supported (s2idle -> shallow -> deep) to be the default, but on some machines the kernel will choose s2idle as the default even if deep is supported. https://www.kernel.org/doc/html/v4.18/admin-guide/pm/sleep-states.html#basic-sysfs-interfaces-for-system-suspend-and-hibernation -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
