The card is a GTX 940M.\r\n\r\nAs a workaround, I'm using systemd hooks to rmmod and modprobe bbswitch on suspend and resume. This causes suspend to work properly and not drain battery, but means I have to reboot in order for the GPU to work again. I am currently using the stable version of bumblebee, I am setting no acpi_osi parameter, and am running Linux kernel 4.6.\r\n\r\n- bumblebee stable 3.2.1\r\n- bbswitch 0.8\r\n- Linux 4.6\r\n- Bios v1.11\r\n- Not setting any `acpi_osi` kernel parameter\r\n\r\nYou mentioned bios v1.14, I can update if you think it will make a difference, but I probably won't otherwise.\r\n\r\nIf there is any other information I can provide I will be happy to do so.\r\n\r\nacpidump: https://gist.github.com/jacobmischka/e7f3d1da3039a0f207635d235c10f5a4"},"comment":{"url":"https://api.github.com/repos/Bumblebee-Project/bbswitch/issues/comments/233190006","html_url":"https://github.com/Bumblebee-Project/bbswitch/issues/132#issuecomment-233190006","issue_url":"https://api.github.com/repos/Bumblebee-Project/bbswitch/issues/132","id":233190006,"user":{"login":"Lekensteyn","id":164530,"avatar_url":"https://avatars.githubusercontent.com/u/164530?v=3","gravatar_id":"","url":"https://api.github.com/users/Lekensteyn","html_url":"https://github.com/Lekensteyn","followers_url":"https://api.github.com/users/Lekensteyn/followers","following_url":"https://api.github.com/users/Lekensteyn/following{/other_user}","gists_url":"https://api.github.com/users/Lekensteyn/gists{/gist_id}","starred_url":"https://api.github.com/users/Lekensteyn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Lekensteyn/subscriptions","organizations_url":"https://api.github.com/users/Lekensteyn/orgs","repos_url":"https://api.github.com/users/Lekensteyn/repos","events_url":"https://api.github.com/users/Lekensteyn/events{/privacy}","received_events_url":"https://api.github.com/users/Lekensteyn/received_events","type":"User","site_admin":false},"created_at":"2016-07-17T16:21:12Z","updated_at":"2016-07-17T16:21:12Z","body":"Can you post the output of `lspci -nn -s01:`? If you happen to have an audio device there that is not suspended, the pcie root port will also not suspend. It is also important to note that this module will only save power when the appropriate pci/pm patches are applied (possibly in Linux 4.8 now).\r\n\r\nAlso, do you need to use Bumblebee for acceleration or would you just like to save power?"}}
