RHEL 6: View boot messages "behind" the splash screen
Solution 1:
Alt + d works also. I remember it as "details".
Solution 2:
- Interrupt the GRUB by hitting the Esc key
- Press e to edit
- Remove the
rhgb quietat the kernel line - Enter and hit b to continue booting
Solution 3:
If I understand what you are asking, you should just be able to hit ESC to show the startup messages. To make it go away permanently, remove "rhgb" from the kernel line in /etc/grub.conf.
