Adding ubuntu-emulator task, it's still not clear what actually prevents the rendering.

Hey, I just tried this on vivid, and seems to work fine. On first boot it does take a while to complete, but it does start. There is a bug where the dash starts a little too early and unity8 misses it, that you can fix by SSHing into the emulator and going restart unity8-dash. ** Changed in: unity8 (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396919 Title: unity8 display blank in emulator, host utopic, rtm-14.09 instance.

When you say vivid you mean for the desktop or the emulator image.

I just installed fresh utopic and followed the steps, everything worked fine here. To clarify: you don't even get the panel / welcome screen / greeter, the whole screen of the emulator is blank? Is that permanent? If you go sudo stop lightdm; sudo start lightdm, does it come back? How about stop unity8; start unity8? If you *do* see the panel, just no dash, does restart unity8-dash help?

[Bug 1396919] Re: unity8 display blank in emulator, host utopic, rtm-14.09 instance.
Hi, Michal The PES mainstream team identified that it has a higher probability happend, if the user runing the emulator on a virtualzation disabled machine. The user does not even get the panel / welcome screen / greeter, the whole screen of the emulator is blank. It comes back *sometimes* if restart unity8 by $ kill -9 $(pidof unity8) $(pidof unity8-dash) Here is my theory - When disabled virtualzation in emulator, the system will be running very slow, and it's possible incrase odds for a race condition of the unity8/unity8-dash. Reference - The developer need to have VT-X/AMD-V hardware for the emulator, and it need to be enabled from BIOS to have better emulator performance. The developer can check with the following command - # check if the hardware support virtualzation $ grep -e svm -e vmx /proc/cpuinfo # check if it's enabled from BIOS $ sudo apt-get install cpu-checker kvm-ok -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396919 Title: unity8 display blank in emulator, host utopic, rtm-14.09 instance.
