disable startup graphic
disable startup graphic
I can't figure out how to disable the startup graphic in centos 7 64bit. In centos 6 I always did it by removing "rhgb quiet" from /boot/grub/grub.conf but there is no grub.conf in centos 7. I also tried yum remove rhgb but that wasn't present either.
<moan> I've never understood why the devs include this startup graphic, I see loads of users like me who want a text scroll instead.</moan>
Thanks for any help.

Re: disable startup graphic
The file to amend now is /boot/grub2/grub.cfg and also /etc/default/grub. If you only amend the defaults file then you need to run grub2-mkconfig -o /boot/grub2/grub.cfg afterwards to get a new file generated but you can also edit the grub.cfg file directly though your changes will be wiped out next kernel install if you don't also edit the 'default' file.
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: disable startup graphic
thanks for that, I did the edits and now the scroll is back.
Re: disable startup graphic
The preferred method to do this is using the command plymouth-set-default-theme.
If you enter this command, without parameters, as user root you'll see something like
>plymouth-set-default-theme
charge
details
text
This lists the themes installed on your computer. The default is 'charge'. If you want to see the boot up details you used to see in version 6, try
>plymouth-set-default-theme details
Followed by the command
>dracut -f
Then reboot.
This process modifies the boot loader so you won't have to update your grub.conf file manually everytime for each new kernel update.
There are numerous themes available you can download from CentOS or in general. Just google 'plymouth themes' to see other possibilities, if you're looking for graphics type screens.

Editing /etc/default/grub to remove rhgb quiet makes it permanent too.

Re: disable startup graphic
I tried both TrevorH's and LarryG's methods, and LarryG wins.
Editing /etc/default/grub to remove "rhgb quiet" gave me the scrolling boot messages I want, but it reduced maxmum display resolution (nouveau driver) from 1920x1080 to 1024x768! I put "rhgb quiet" back in and got my 1920x1080 back.
Then I tried "plymouth-set-default-theme details; dracut -f", and got verbose booting without loss of display resolution. Thanks LarryG!

Re: disable startup graphic
I have used this mod to get back the details for grub boot, thanks to all for that info.
However when I am watching it fills the page and then rather than scrolling up as it did in V5 it blanks and starts again at the top. Of course there is FAIL message right before it blanks that I want to see and I can't slam the Scroll Lock fast enough to catch it. Anyone know how to get the details to scroll up rather than the blank and re-write?

Re: disable startup graphic
Yeah the scroll lock/ctrl+q/ctrl+s will not work with systemd you can't pause the screen like you used to be able to (it was a design choice, due to parallel daemon launching, apparently).
If you do boot, you can always use journalctrl to view the logs.
In Fedora you can use journalctl --list-boots to list boots (not 100% sure about CentOS 7.x - perhaps in 7.1 or 7.2?). You can also use things like journalctl --boot=-1 (the last boot), and parse the log at you leisure.

Re: disable startup graphic
Thanks for the followup aks. Actually I have found that the Scroll Lock does pause (Ctrl-S/Q not) but it all goes by so fast that I'm not fast enough to stop it before the screen blanks and then starts writing again. What I am really wondering is how to get the screen to scroll up when it gets to the bottom of the screen rather than blanking and starting to write again at the top. That is annoying!aks wrote:Yeah the scroll lock/ctrl+q/ctrl+s will not work with systemd you can't pause the screen like you used to be able to (it was a design choice, due to parallel daemon launching, apparently).

Yes it is and no you can't. Kudos to Lennard for making or lives so much shitter....
