While this was triggered by a linux change, I think it's a d-i bug, not a linux bug. The root problem is that debian-installer-startup's stdin is /dev/console, which rootskel thinks indicates a serial console. When I do the same test in kvm, I find that debian-installer-startup's stdin is /dev/tty0.
I'm trying to narrow down the cause of this discrepancy at the moment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745947 Title: Fails to display video after grub (kernel lacks video output) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
