This bug has been fixed now, no longer happening. Marking as Invaild, if anyone still able to reproduce using latest natty kernel please re-open. ** Changed in: grub2 (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685445 Title: grub2 sometimes fails to boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 685445] Re: grub2 sometimes fails to boot
Anton, if you're getting to the point of seeing safe graphics mode, then you have a different bug. This bug is about not even being able to see the boot menu. (In any case, the GRUB menu does not include anything called safe graphics mode, so I guess you must be talking about a live CD or a USB stick or something.) PeterPall, could you try version 1.99~20101221-1ubuntu1? That fixes a subtle memory corruption problem (bug 686705) which would have happened before the boot menu was displayed. It's possible that this might have been your problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685445 Title: grub2 sometimes fails to boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 685445] Re: grub2 sometimes fails to boot
Today I seem to have encountered the problem even if the line GRUB_TERMINAL=console of the file /etc/default/grub wasn't commented out and even if I ran sudo update-grub after making this change -which seems to indicate that it might not be a graphics-related problem after all.

I still cannot load normally to Ubuntu even after kernel update. I can just choose safe graphic mode and then boot. Otherwise I get black screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685445 Title: grub2 sometimes fails to boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
