    Re: Grub Text Mode (How to remove purple screen?)

    Hi, That provided me the startup text I was looking for, and the system booted to the unity greeter which I wanted.

    It is still strange that I can't get a higher resolution text based output (which is what removing splash and quiet were supposed to do), but for not this is good enough.

    thanks

    I think what you want to do is:

    Code:
    GRUB_CMDLINE_LINUX_DEFUALTS=""
    GRUB_CMDLINE_LINUX=""
    and have

    Code:
    GRUB_TERMINAL=console
    uncommented

    Re: Grub Text Mode (How to remove purple screen?)

    The ubuntu plymouth wiki states:
    If you want to see the text-based boot messages (which use the Plymouth "details" plugin, press the ESCAPE key at any point when Plymouth is running. Note that the ESCAPE key acts as a toggle, so you can keep switching between graphical and text mode as required.
    Therefore, why not use the "details" module?
    Here's what I did to get some text displayed during boot through plymouth.

    1. It turns out there's already a "details" plymouth theme in ubuntu. Normally, it isn't listed among the alternative themes on your systems. You can check it out with the following command
      Code:
      sudo update-alternatives --list default.plymouth
      If you see the line below among the output you can skip to step 3.
      Code:
      /lib/plymouth/themes/details/details.plymouth
    2. Add the "details" theme to the plymouth alternatives:
      Code:
      sudo update-alternatives --install /lib/plymouth/themes/default.plymouth default.plymouth /lib/plymouth/themes/details/details.plymouth 10
      Go to step 1 and repeat the test, just to make sure the new them has been added.

    3. Switch to the new theme by running:
      Code:
      sudo update-alternatives --config default.plymouth
      Then
      Code:
      sudo update-initramfs -u
    4. Edit /etc/default/grub and remove parameters "quiet" and "splash" from the line
      Code:
      GRUB_CMDLINE_LINUX_DEFAULT="...."
      Update grub by running
      Code:
      sudo update-grub

    Reboot and you should now see a list of messages on boot.

    OPTIONAL
    If you're having video issues on boot (plymouth starts late, no graphics at all, etc.), and depending on your config, you may want to check the following out:
