Don't get too excited. Although I fixed the crash you should just expect a black screen in Mir 0.25.0 instead, which is now bug 1639745.
I don't know what that error is you report but doesn't matter. VirtualBox won't give you anything better than a black screen even with Mir 0.25.0. See bug 1639745 at least. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584894 Title: unity-system-compositor (or any Mir server) crashes on start-up with "Mir fatal error: Failed to schedule page flip" on VirtualBox Graphics Adapter and QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1584894/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
