LPIC-2 Linux Kernel and System Startup Practice Question
Exhibit
Refer to the exhibit. $ cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=""
An administrator wants to disable the graphical splash screen during boot. What change should be made in /etc/default/grub?
⚠ Common exam trap
A common mix-up: candidates confuse 'quiet' with 'splash', thinking that removing 'quiet' alone disables the splash screen, when in fact 'splash' is the specific parameter controlling the graphical boot animation.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT
The graphical splash screen during boot is controlled by the 'splash' kernel parameter. Removing 'splash' from GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub disables the splash screen, allowing verbose boot messages to be displayed. This parameter is passed to the kernel via the bootloader, and its absence prevents the plymouth or similar splash service from activating.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set GRUB_CMDLINE_LINUX="nosplash"
Why it's wrong here
Although 'nosplash' might work, the standard approach is to remove 'splash' from the default line.
- ✗
Remove 'quiet' from GRUB_CMDLINE_LINUX_DEFAULT
Why it's wrong here
Removing 'quiet' shows verbose boot messages but splash remains.
- ✗
Set GRUB_TIMEOUT=0
Why it's wrong here
This eliminates the menu timeout but does not disable splash.
- ✓
Remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT
Why this is correct
The 'splash' parameter enables the graphical splash screen; removing it disables it.
