| | 108 | > The following line in /etc/grub.d/10_linux is present in Natty but not Maverick: |
| | 109 | > {{{ |
| | 110 | > GRUB_CMDLINE_EXTRA="$GRUB_CMDLINE_EXTRA vt.handoff=7" |
| | 111 | > }}} |
| | 112 | > And then these were the steps I took, to confirm my analysis of the bug: |
| | 113 | > 1. (1) Edit /etc/grub.d/10_linux (e.g. "sudo nano -w /etc/grub.d/10_linux") and comment out the line containing "vt.handoff", or change the number from 7 to some lower number. (I tried it both ways; they both worked.) |
| | 114 | > 1. (2) Run "sudo update-grub" to apply the new configuration. |
| | 115 | > 1. (3) Reboot. A usable virtual terminal with a login prompt comes up automatically. |

| | 118 | > After reading this bug I've commented out the "for word in $GRUB_CMDLINE_LINUX_DEFAULT; do" clause in /etc/grub.d/10_linux, and also changed GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub to "noplymouth" instead of "quiet splash", and now my boot is working great and I get the expected login prompt. |
