I am getting the same issue but with alpha 4 after installing the latest updates today.
I had no boot problem after upgrading 8.10 to 9.04 alpha 4. If I disable the splash screen the system boots without any problem. That confirms the solution written by Patrick Kilgore. My computer is an Acer 5315 laptop with Intel X3100 graphics. -- Jaunty alpha 2 black screen after ubuntu progress bar https://bugs.launchpad.net/bugs/310301 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
