For a completely unrelated problem, I ran update-grub following the instructions in user62644's answer to this post. Ever since, the GUI has been loading by default upon boot, and I have to type Ctrl+Alt+F1 to access the bash shell. I would like the bash shell to load by default upon startup, and just type startx whenever I need the GUI. I'm running Ubuntu 12.04 LTS.

Edit /etc/default/grub and change this:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"

to this:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet text"

This assumes you actually need the acpi=noirq that was in the linked answer. I can't tell you that, it depends on your hardware. Anyway, once you've done this, refresh grub:

sudo update-grub

And you should now load directly to text.

  • Thank you. I've been wondering about the `acpi=noirq` part. Originally, the settings were `GRUB_CMDLINE_LINUX_DEFAULT=""` and changing it did not solve the problem it claimed to solve, aka. system hangs upon shutdown (which I solved by using `shutdown -HR`). To make things short, I have no clue whether or not I need `acpi=noirq`... – biohazard Mar 11 '14 at 04:40
  • @biohazard you probably don't, that is usually suggested to solve some graphics problems. You certainly did not solve your shutdown issues by running `shutdown -r` though, that just reboots. Anyway, the main thing is adding `text`, that should cause you to boot into text mode. – terdon Mar 11 '14 at 04:42
  • Sorry, it shut down properly when using `shutdown -HR now` (power actually went off). I actually haven't tried `shutdown -r`. Edited my comment above. – biohazard Mar 11 '14 at 04:43
  • Thank you. It seems like a link is missing in your post after "More details here:" – biohazard Mar 11 '14 at 04:48
  • OMG sorry it was `shutdown -HP now`!!! I'm so confused. – biohazard Mar 11 '14 at 04:52
  • @biohazard yes, sorry, I didn't add a link cause I couldn't find the official docs on this and I forgot to delete the text. – terdon Mar 11 '14 at 05:00

Use

sudo update-rc.d lightdm remove

And you will see desired bash logon shell on startup

To restore:

sudo update-rc.d lightdm defaults

  • Thank you! I hesitated which answer to pick, but I felt that @terdon's answer also took into account the context of the previous instructions I had followed. I will remember your solution in case I encounter this again in the future. – biohazard Mar 11 '14 at 04:48
