Just wondered if you happened to see these?

Power Management Bug P:Medium

[edit by @Lekensteyn] This issue affects newer laptops (from about 2015-2016) w…ith Skylake and GTX 9xxM/10xx cards/ A workaround exists for some laptops, see https://github.com/Bumblebee-Project/Bumblebee/issues/764#issuecomment-234494238 [/edit] ___ I'm having a weird issue, and I'm not sure what kind of debug information is neccesary, but let me know what to give and I'll supply anything you need. When I start my graphics (lxdm), I get a freeze (keyboard stops working, no response on monitor at all, even log files stop working), but I can work around this by enabling the graphics card before starting graphics. System (installed with `bumblebee-nvidia` in debian testing repos): ``` Debian Testing GTX 965M Nvidia Proprietary Driver: 352.79 Laptop: SAGER NP7258 ``` Optirun --version: ``` optirun (Bumblebee) 3.2.1 Copyright (C) 2011 The Bumblebee Project License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>. This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. ``` My laptop seems to not work without optimus, the intel drivers work fine, but trying to run w/o the intel drivers (nvidia only) seems to result in a frozen screen. Using the workaround works perfectly for me, however. Steps to Reproduce: 1. `systemctl start bumblebeed` 2. `systemctl start lxdm` 3. Freeze occurs Workaround: 1. `systemctl start bumblebeed` 2. `echo "ON" >/proc/acpi/bbswitch` 3. `systemctl start lxdm` Unfortunately, any X11 log files don't seem to survive after my system freezes (they show everything completed successfully, probably from the previous successfull boot). If you know any way of retreiving them I'd be happy to supply them though! (When the system freezes, even my shell history file gets corrupted). I did have to make some changes to my config files to get things to work in my situation though, I'll post anything I remember changing below. Let me know if you need any more information, I am happy to supply it! Without bumblebee, my laptop would be unusuable :+1: ### bumblebee.conf ``` # Configuration file for Bumblebee.
