I've migrated to the LST Enablement Stack and after a few days agree that this seems to have been resolved with the newer kernel and xorg components (although it's hard to know for sure - on the 3.16 kernel I think I would have had a problem by now, however).
That's for 3.19.0-26-generic #28~14.04.1-Ubuntu on Ubuntu 14.04.3 LTS. Steps to resolve issue were simply: $ sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video- all-lts-vivid xserver-xorg-input-all-lts-vivid libwayland-egl1-mesa-lts- vivid linux-signed-generic-lts-vivid and reboot (see instructions in link provided by Øyvind Stegard). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384297 Title: After system resume, Intel i915 graphics hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1384297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
