Apart from the strange errno in the logs above.. to allow mir to run on vbox we need to add page flipping and the default implementation of prime to the vbox drm driver:
http://www.virtualbox.org/svn/vbox/trunk/src/VBox/Additions/linux/drm/ page flipping has been adde here: https://github.com/xknight/vboxvideo That plus mesa 10.3 and mir should work. Maybe there is also a way to use the virtualbox GL implementation? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mir in Ubuntu. https://bugs.launchpad.net/bugs/1366805 Title: Can't log in to Unity8 in VirtualBox; Mir crashes with "std::exception::what: Error opening DRM device" Status in Mir: New Status in “mir” package in Ubuntu: New Bug description: When I try to login to Unity Next the system-compositor seems to crash immediately.
