How to hide Grub bootup details and background

Postby stark » 2019-08-05 11:17

Hi, I was able to to stop grub from halting the system with the grub menu, but how do I remove the kernal and error messages that show prior to the login screen on debian?

Hiding error messages is not good idea, in my opinion. ;-)

HI, thanks for your reply, I tried that but it hid nothing, I want it to hide the kernel version being booted, the os version and the following error messages that appear, they are not serious errors and show on both systems I have Debian installed on, for security and also to bootup quicker I would like to hide them.

I also tried

GRUB_CMDLINE_LINUX_DEFAULT=quiet
GRUB_CMDLINE_LINUX="console=tty12"

made no difference, OS version, Kernel version shows, followed by error messages then it goes to the login screen.

I think you can hide the OS & kernel versions by editing /etc/ussue & /etc/motd
Code: Select all
man issue
man motd

To remove the error messages fix the errors. I can't help you with that unless you share them with us.

Thanks for the help, I wiped them out, the files and saved them blank but it still shows the Os version at the top, then the kernel beneath then the error messages load afterwards.

GRUB echoes the kernel version when loading, see https://forum.mxlinux.org/viewtopic.php ... 43#p502643 to get rid of that.

And we really do need to know what these mysterious error messages are if you want help fixing them. If they are top secret then try entering them into a search engine (which will probably be quicker than posting them here).

Thank you modifying the grub config echo works, the error messages arent top secret they are just too long, I will take a picture and add write them down as I cannot take a screenshot during boot, thanks for your help :)

Ok, this is the error message

0.3223980 ACPI error: Needed type reference, found [integer]00000009
2f5a (20180910/EXRESOP-69

then it repeats that error message about ACPI 2x more except it references

dswexec-427

&

psparse-516

Instead of EXRESOP-69 TO

I did, it worked :), thanks, it just goes black for a second then loads to the login screen.

I assume teh ACPI errors aren't serious?

I'm not sure tbh, probably best to ask a search engine about them.
