GRUB changes

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

• You can change the default from 0 to any number, corresponding to the entry in the Grub bootup menu (first entry is 0, second is 1, etc.)
• You can change the "hidden timeout" (no menu); and also display the countdown (GRUB_HIDDEN_TIMEOUT_QUIET=false)
• You can force the grub menu to show by commenting out the two GRUB_HIDDEN lines with a # at the beginning of the line

How to boot in compatibility mode after install

sudo vi /etc/default/grub

Save & exit.

Change line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to:

GRUB_CMDLINE_LINUX_DEFAULT="noapic noacpi nosplash irqpoll"

Update grub:

sudo update-grub

Graphic problems....

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset nosplash irqpoll"

This solves when Mint shows login screen but when you login you see only cursor and nothing else.

Disable Linux Mint logo and display the boot messages instead

To disable the Linux Mint logo and display the boot messages instead, you'll need to modify the GRUB bootloader settings. Here are the steps to do this:

1. **Open a Terminal**: You can do this by pressing `Ctrl + Alt + T`.

2. **Edit the GRUB Configuration File**:

  ```
  sudo nano /etc/default/grub
  ```

3. **Modify the GRUB_CMDLINE_LINUX_DEFAULT line**:

  Find the line that looks like this:
  ```
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  ```
  and change it to:
  ```
  GRUB_CMDLINE_LINUX_DEFAULT=""
  ```

4. **Update GRUB**:

  After making the changes, save the file by pressing `Ctrl + O`, then `Enter`, and then exit the editor by pressing `Ctrl + X`. Then, update GRUB with the following command:
  ```
  sudo update-grub
  ```

5. **Reboot**:

  Restart your computer to see the changes. You should now see the boot messages instead of the Linux Mint logo.

By removing the `quiet` and `splash` options from the GRUB configuration, you will be able to see detailed boot messages during startup.
