Public bug reported: I've started observing this bug since i've started using NVidia's additional drivers (yesterday). Before that I was using nouveau, which happened to use the builtin Intel GPU and not the NVidia card.
I have an external monitor which I usually connect to the laptop. I have it configured so it's the only screen when it's connected. When I unplug it, automatically the laptop's builtin screen turns on, and when I plug it, the laptop's builtin screen turns off. This has worked just fine until yesterday. Then I switched to NVidia's proprietary drivers. Now the problem, 100% systematically reproducible, is as follows: - I disconnect the external screen (and external keyboard and mouse), move my laptop and start using it alone. At the beginning everything works fine, then: - from time to time (every few minutes), the system seems to freeze: - mouse cursor doesn't move. Nothing responds to touchpad movements or clicks - nothing apparently responds to keystrokes, such as alt+tab to switch window, or Ctrl+Alt+T to open a terminal. I'm not sure this ever happened while I was typing and had a focused window where to type, so I cannot tell for sure it wouldn't respond to typing - no signs of abnormal CPU consumption, though, nor of disk activity - hitting ctlr+Alt+F1 does work and immediately brings the virtual console - hitting ctrl+Alt+F7 brings the graphics screen again and it works, that is, it fixes the issue, reesstablishing normal functioning - unless it happens again. The first time I observed it (this is the second), this also happened: - then I plug in the external monitor again. It turns on, shows the screen output as expected; the builtin screen turns off, everything looks normal - except the system is frozen again - and this time not even Ctrl+Alt+F1 work. Completely frozen. No way out except a hard reboot - unplugging the external monitor doesn't fix the issue, either ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xserver-xorg-core 2:1.15.1-0ubuntu2 ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 NonfreeKernelModules: nvidia .proc.driver.nvidia.gpus.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 331.38 Wed Jan 8 19:32:30 PST 2014 GCC version: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Wed Aug 6 19:51:09 2014 DistUpgraded: 2014-05-24 19:43:23,984 DEBUG enabling apt cron job DistroCodename: trusty DistroVariant: ubuntu DkmsStatus: bbswitch, 0.7, 3.13.0-32-generic, x86_64: installed nvidia-331, 331.38, 3.13.0-32-generic, x86_64: installed vboxhost, 4.3.14, 3.13.0-32-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device [1025:0647] NVIDIA Corporation GF117M [GeForce 610M/710M/820M / GT 620M/625M/630M/720M] [10de:1140] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] GeForce 710M [1025:0691] InstallationDate: Installed on 2013-10-11 (299 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Acer Aspire V3-571G ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-32-generic.efi.signed root=UUID=5830b30e-69e8-4bb4-8a2b-bc2b43c7414a ro quiet splash vt.handoff=7 SourcePackage: xorg-server UpgradeStatus: Upgraded to trusty on 2014-05-24 (74 days ago) dmi.bios.date: 10/15/2012 dmi.bios.vendor: Acer dmi.bios.version: V2.07 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: VA50_HC_CR dmi.board.vendor: Acer dmi.board.version: Type2 - Board Version dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: V2.07 dmi.modalias: dmi:bvnAcer:bvrV2.07:bd10/15/2012:svnAcer:pnAspireV3-571G:pvrV2.07:rvnAcer:rnVA50_HC_CR:rvrType2-BoardVersion:cvnAcer:ct10:cvrV2.07: dmi.product.name: Aspire V3-571G dmi.product.version: V2.07 dmi.sys.vendor: Acer version.compiz: compiz 1:0.9.11.2+14.04.20140714-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.52-1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.3-0ubuntu0.1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.3-0ubuntu0.1 version.nvidia-graphics-drivers: nvidia-graphics-drivers N/A version.xserver-xorg-core: xserver-xorg-core 2:1.15.1-0ubuntu2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.3.0-1ubuntu3.1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.910-0ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 xserver.bootTime: Wed Aug 6 15:19:13 2014 xserver.configfile: /etc/X11/xorg.conf xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.15.1-0ubuntu2 ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug compiz-0.9 trusty ubuntu -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1353620 Title: Laptop Screen systematically freezes every few minutes when external screen disconnected; Ctlr+Alt+F1,Ctrl+Alt+F7 fixes the issue.
