I too am having the Unity not starting problem. It was working this morning but then I applied the latest updates and now it's broken. I'm using Ubuntu Desktop 16.04 on VirtualBox 5.1.2 on Windows 10 Pro 64 bit. I've tried: - downgrading VirtualBox to version 5.0.26 - changing the VMs chipset to ICH9 (was PIIX3) - changing the VM to having 1 vCPU (was 4) - booting the 4.4.0-28 kernel instead of the default 4.4.0-31 - enabling PAE/NX - changing networking to not use virtio-net - changing paravirtualisation acceleration from Default (KVM) to none
None of the above has made any difference (so I've undone all those changes). My VM is a default setup VirtualBox Ubuntu VM with 4 GB RAM, 4 vCPUs, USB 3.0 enabled, virtio-net. Recent Ubuntu updates seem to be the culprit. I noticed that since a couple of days ago, every fifth boot will result in an NMI watchdog timeout with CPU stuck for 23s. Is this a DBUS issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605836 Title: Unity not starting after upgrade on dell, did dconf reset and serid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1605836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
