I have the same problem on 12.04 64bit after installing the trusty Xstack with
apt-get install -V libglapi-mesa-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty xserver-xorg-input-all-lts-trusty xserver-xorg- video-all-lts-trusty libgl1-mesa-dri-lts-trusty x11-xserver-utils-lts- trusty libglapi-mesa-lts-trusty:i386 libgl1-mesa-dri-lts-trusty:i386 libgl1-mesa-glx-lts-trusty:i386 libgles2-mesa-lts-trusty libglapi-mesa- lts-trusty mesa-vdpau-drivers-lts-trusty kernel 3.13.0-30-generic #54~precise2, nvidia-331-updates 331.38-0ubuntu0.0.1 Xorg message after black screen: (after wake up from hibernate) (EE) NVIDIA(GPU-0): WAIT: (E, 0, 0x857d) It seems to be a combination of kernel, Xorg-server, X-components, which triggers this bug, because without the trusty Xstack there was no black screen issue with this kernel version. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1283938 Title: [Samsung NP535U4X-S01TH] Ubuntu 14.04 blank screen after wakeup from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283938/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
