Now the laptop will freeze as above (blinking light) if i start the VM while the CPU is already under load with chrome/something *2nd display in dual monitor extended config is flashing after standby - this wasnt happening in 15.10 please let me know if you need further info, 16.04 seems like a decent OS bar these issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565924 Title: [Xenial] Freeze when docking Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1565924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
