Public bug reported: Tested on HP ProBook 450 G1 notebook with Linux Mint 17 (based on Ubuntu 14.04) on a lot of kernel versions up to 4.4.0-47-generic #68~14.04.1.
While resuming from stand-by works perfectly, resuming from hibernation does not work out-of-the-box (after unlocking the hard disk with dm- crypt, the screen remains black). To make resume from hibernate work, the "acpi_osi=Linux" kernel boot parameter must be used. Using it successfully right now with kernel version "Ubuntu 4.4.0-47.68~14.04.1-generic 4.4.24". ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: xenial ** Attachment added: "lspci-vnvn.log" https://bugs.launchpad.net/bugs/1701081/+attachment/4904896/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1701081 Title: HP ProBook 450 G1, resume from hibernate does not work unless acpi_osi=Linux boot parameter is used Status in linux package in Ubuntu: Incomplete Bug description: Tested on HP ProBook 450 G1 notebook with Linux Mint 17 (based on Ubuntu 14.04) on a lot of kernel versions up to 4.4.0-47-generic #68~14.04.1.
