FYI, I did look at https://bugs.launchpad.net/unity/+bug/1301125, however in that bug the unity freeze occurs only after the system is locked after idle time. In my case, the unity freeze after manually suspending and then resuming from freeze after 10-15 minutes.

As a result, the only way to fix the situation is to hard reboot the system. Steps to reproduce: 1. Suspend laptop 2. Wait for at least 10-15 minutes 3. Try resuming What happens: Black screen with the mouse cursor visible. However the whole screen is frozen. No keyboard or mouse input is accepted. As a result, I cannot switch to any vt to reboot or restart the lightdm process What should happen: Unity lockscreen is shown where one can enter the password and return to the user session gnome-screensaver: 3.6.1-0ubuntu13 amd64 [Installed] ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity 7.2.0+14.04.20140411-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-24.46-generic 3.13.9 Uname: Linux 3.13.0-24-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu2 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: Sun Apr 13 13:56:56 2014 DistUpgraded: 2014-02-27 11:46:48,360 DEBUG enabling apt cron job DistroCodename: trusty DistroVariant: ubuntu GraphicsCard: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:3801] NVIDIA Corporation GK107M [GeForce GT 755M] [10de:0fcd] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:3801] InstallationDate: Installed on 2013-09-18 (207 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Alpha amd64 (20130802) MachineType: LENOVO 20217 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-24-generic.efi.signed root=UUID=63532c2e-8584-466e-8215-2d6770489a00 ro quiet splash vt.handoff=7 SourcePackage: unity UpgradeStatus: Upgraded to trusty on 2014-02-27 (45 days ago) dmi.bios.date: 06/04/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 74CN32WW(V2.02) dmi.board.asset.tag: YB00228460 dmi.board.name: 20217 dmi.board.vendor: LENOVO dmi.board.version: 31900003WIN8 STD MLT dmi.chassis.asset.tag: YB00228460 dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo IdeaPad Y510P dmi.modalias: dmi:bvnLENOVO:bvr74CN32WW(V2.02):bd06/04/2013:svnLENOVO:pn20217:pvrLenovoIdeaPadY510P:rvnLENOVO:rn20217:rvr31900003WIN8STDMLT:cvnLENOVO:ct10:cvrLenovoIdeaPadY510P: dmi.product.name: 20217 dmi.product.version: Lenovo IdeaPad Y510P dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.11+14.04.20140409-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.52-1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.0-4ubuntu4 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.0-4ubuntu4 version.xserver-xorg-core: xserver-xorg-core 2:1.15.0-1ubuntu7 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 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: Sun Apr 13 13:51:07 2014 xserver.configfile: default xserver.errors: Failed to load module "nvidia" (module does not exist, 0) Failed to load module "nvidia" (module does not exist, 0) NOUVEAU(G0): Failed to initialise context object: 2D_NVC0 (0) NOUVEAU(G0): Error initialising acceleration.
