Why disable graphical boot?

If I’ve connected a monitor to a physical server or consoled into a virtual machine during boot, I’d like to see what’s going on without having to hit any key combos etc. I want the info the be right there scrolling past!

How to:

Using the tool grubby we can see what the current kernel boot arguments are

grubby --info=ALL


We can see the options “quiet rhgb” listed in the arguments line
quiet” reduces the verbose output to console
rhgb” stands for RedHat Graphical Boot which puts a nice display while booting but no info as to what’s happening

To remove the options “quiet” and “rhgb” from all installed kernels:

grubby --update-kernel=ALL --remove-args="rhgb quiet"

After the above change, all subsequent boots will scroll dmesg and service startup text in the console
