** Description changed: I instaled bumblebee-nvidia for Optimus support in my Asus laptop and bbswitch-dkms causes forced shutdown, even if I reboot system. My HDD makes a loud noise, It is as if the power went out, the forced shutdown is very violent (there is not plymouth shutdown screen). I know that bbswitch is used for turn on and turn off nvidia card, but somehow it is affecting shutdown/reboot. Steps to reproduce: - - Install nvidia-319-updates (319.49) and bumblebee-nvidia; + - Install nvidia-319-updates (319.49) and bumblebee-nvidia (in trusty, nvidia-331-updates and bumblebee package); - Configure bumblebee files to works with nvidia module; - Reboot system, bbswitch will be active in the next login; - - After login system, try to turn off the system, or reboot. System will causes a forced shutdown; + - After login system, try to turn off the system, or reboot. System will causes a forced shutdown (it seems it can be reproduced if you use nvidia card in the session); There is workaround to avoid this problem, runs: sudo modprobe -r bbswitch before every shutdown or reboot. + Or add the next initscript (/etc/init/bbswitch.conf) : + + description "Save power by disabling nvidia on Optimus" + author "Lekensteyn <lekenst...@gmail.com>" + start on runlevel [2345] + stop on runlevel [016] + pre-start exec /sbin/modprobe bbswitch load_state=0 unload_state=1 + pre-stop exec /sbin/rmmod bbswitch + + + More info: https://github.com/Bumblebee-Project/bbswitch + Please, this is a important (and dangerous) bug, anyone that tries to get Optimus tecnology works in Ubuntu and uses Bumblebee probably will get a HDD broken in a few months of use, without knowing why. --- + + ProblemType: Bug + DistroRelease: Ubuntu 14.04 + Package: ubiquity 2.17.1 + ProcVersionSignature: Ubuntu 3.12.0-7.15-generic 3.12.4 + Uname: Linux 3.12.0-7-generic x86_64 + ApportVersion: 2.12.7-0ubuntu2 + Architecture: amd64 + CasperVersion: 1.336ubuntu1 + Date: Tue Dec 17 01:55:05 2013 + LiveMediaBuild: Xubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20131216) + ProcEnviron: + LANGUAGE=en_US + TERM=xterm + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + SourcePackage: ubiquity + UpgradeStatus: No upgrade log present (probably fresh install) Ubuntu Saucy Salamander (development branch) \n \l Linux sergio-X751JB 3.11.0-8-generic #15-Ubuntu SMP Fri Sep 20 04:11:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux baseboard-manufacturer: ASUSTeK COMPUTER INC. baseboard-product-name: X750JB baseboard-version : 1.0 system-manufacturer : ASUSTeK COMPUTER INC. system-product-name : X750JB system-version : 1.0 bios-vendor : American Megatrends Inc. bios-version : X750JB.207 bios-release-date : 05/24/2013 optirun (Bumblebee) 3.2.1 bbswitch-dkms: Installed: 0.7-2 Candidate: 0.7-2 Version table: *** 0.7-2 0 500 http://archive.ubuntu.com/ubuntu/ saucy/universe amd64 Packages 100 /var/lib/dpkg/status 00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) 01:00.0 3D controller [0302]: NVIDIA Corporation GK208M [GeForce GT 740M] [10de:1292] (rev ff) (prog-if ff) ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: bbswitch-dkms 0.7-2 ProcVersionSignature: Ubuntu 3.11.0-8.15-generic 3.11.1 Uname: Linux 3.11.0-8-generic x86_64 ApportVersion: 2.12.4-0ubuntu1 Architecture: amd64 Date: Thu Sep 26 23:41:36 2013 InstallationDate: Installed on 2013-09-20 (6 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Alpha amd64 (20130920) MarkForUpload: True SourcePackage: bbswitch UpgradeStatus: No upgrade log present (probably fresh install)
