I am affected by a bug which looks just as this one, and appeared in in apparently the same version of unity package, yet I can't tell if it's indeed the same - for I am using AMD graphics. If this is the same bug, I might provide additional information.
Can you please share your output when running `unity`? In my case it complains - among many warnings and other info - that plugin 'opengl' failed to load. This seems to be a significant clue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1154431 Title: Unity doesn't start up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1154431/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
