I'm failing to reproduce this unfortunately. I'm also failing to create a libertine container. It was failing due to bug 1653973, so I installed silo 2341, but now it fails with:
Failed to download http://images.linuxcontainers.org//meta/1.0/index-user LxcContainer.py:254: ERROR: create_libertine_container(): Failed to create container libertine-container-manager:94: ERROR: create(): Failed to create container This is odd, as networking is fine, and I can wget that URL successfully. I've left my AMD laptop running with unity8 for hours yesterday, and no crash. Can you paste more of that unity8.log please? From the output, it indicates that the physical display state changed somehow, or at least Mir thinks it did. Disabling screen blanking was a good idea, but are you sure it worked? How did you try it? Also, what GPU have you got? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1521403 Title: Unity8 crashes with SIGSEGV in Screen::makeCurrent (./src/platforms/mirserver/screen.cpp:406) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtmir/+bug/1521403/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
