hi Chenheting, i have the same issue, I mean this issue is so randomly:
sometimes with white screen but it goes to plymouth, sometimes black or white screen then no plymouth but goes to gdm, sometimes I can hear the hard disk/LED as if it goes to normaly booting but then nothing. I have to note that since about the natty beta 2, this happend really less, I mean there are these white/black screen nearly every times, but less and less stop booting . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/749361 Title: [STAGING] Black screen on boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
