Grub boot options.

vdub12 · May 2, 2012, 5:04am

I have spent a half hour searching Google for this and I can’t find anything.

Is there a website that covers Grub boot options?

I changed the boot splash and changed splash=verbose and removed quiet from the grub list and it did not give me the expected results. I want the system to boot like I hit Esc on the stock boot splash. However, splash=verbose doesn’t show hardly anything and removing quiet makes everything show up. I am looking for something in the middle.

I was hopping to find a site that deals with just the Grub options and what they are for. Example: quiet, showopts, splash=?, etc.

Basically the look I want is a bootsplash that looks just like it does if you hit Esc during normal boot up. I thought that’s what splash=verbose was for but apparently not. All verbose showed was mounting and umounting drives. I’m looking for the basic OK ] or [failed] lines.

This is not a Grub option but a kernel parameter. Try splash=silent or just remove it.

vdub12 · May 2, 2012, 5:27am

I tried splash=silent, that shows the overlay picture and you have to hit Esc to see the boot messages. I want to just see the boot messages without hitting Esc.

please_try_again · May 2, 2012, 5:32am

Then just remove the ‘splash’ parameter.

vdub12 · May 2, 2012, 5:41am

Removing the splash parameter looks exactly like splash=verbose.

I even looked at /usr/src/linux/Documentation/kernel-parameters.txt and splash=?, quiet, and showopts are not even listed as options. Is there maybe a list of secret options, lol.

I hope you have made a copy of the original file?

What happens if you remove splash=silent quiet vga=***

If you use kde

info:grub

in konqueror is useful

please_try_again · May 2, 2012, 6:04am

You can set

SPLASH="no"

in /etc/sysconfig/bootsplash and rebuild initrd … or you can do it in YaST - it should automatically run mkinitrd.

but is this such a big deal to press ESC?

or you can try to use “nosplash”, but I don’t know if this option still works.

splash is included in the initial ramdisk (not an hidden kernel parameter).

# lsinitrd -l /boot/initrd | grep -i splash

It has nothing to do with Grub. Grub has done its job when the kernel is loading.

I removed splash=silent and its the equivalent of splash=verbose.

I removed quiet and it pukes out every terminal message not just the important stuff and OK ], FAIL].

I have not removed vga because I didn’t think it was relevant.

And I do have a back up of my menu.lst.

I just set splash back to silent and rebooted. When I hit Esc it looks exactly how I want it to but I don’t want to have to hit Esc, I want it just to boot that way.

I don’t want to remove the bootsplash completely because I made a cool background for it. I just don’t want the “quiet” bootsplash. I want the nerdy one ;).

Hitting Esc really isn’t a big deal, I just don’t want to and I know its possible because I have seen people do it.

Also I did run mkinitrd and it had no effect. That’s really only relevant when modifying the bootsplash screen I thought.

please_try_again · May 2, 2012, 6:10am

It’s normal here. … Well, I mean “usual”, not “normal”.

please_try_again · May 2, 2012, 6:12am

Yes of course, after changing that or anything else. See if “nosplash” works (?).

vdub12 · May 2, 2012, 6:23am

Nope.

nosplash is the same as splash=verbose

how was I suppose to enter it. I just typed nosplash. should it be splash=nosplash?

vdub12 · May 2, 2012, 6:26am

Just tried splash=nosplash and its the same as splash=verbose but it also takes away the bootsplash theme.

There are issues with the forum ATM, ongoing but being attended to. And the forum software is due to be updated (Monday, 7th I think)

vdub12 · May 2, 2012, 6:34am

I just changed it back to the way I had it with splash=verbose and removed quiet.

This is the closest so far to what I am looking for but it would be nicer with just important messages rather then the entire console log. I wonder if SUSE is doing some voodoo with the Esc key to just show important messages. From the reading I have done on this subject tonight it seams that SUSE is one of the only distros that lets you hit Esc during a silent bootsplash.

Edit: Also many server guys are filtering messages during the bootsplash by terminal. Normal boot I think is on tty1 but the logs are on tty7 or something like that. Or maybe its the other way around.

vdub12 · May 2, 2012, 7:15am

OK I figured it out. I found this info on the Arch wiki. I love Arch, those people think just like me.

This is how you do it if anyone is interested.

splash=verbose console=tty1 loglevel=6

Remove quiet altogether. This still shows a little more then I would like but I may lower the loglevel again to see if that helps.

Here is a link that talks about loglevel’s. Logging data

EDIT: I tried editing my original post with solved in the subject but it will not let me edit it.

vdub12 · May 2, 2012, 7:28am

loglevel=3 is the one I ended up deciding on. Its really close to just hitting Esc on the stock bootsplash.

Thanks guys for your help, I really appreciate it.

That’s the one to get the messages, but in 12.1 verbose is very little
verbose. For systemd you also have to add “systemd.log_level=debug
systemd.log_target=kmsg”, and that would be documented in systemd
documentation. Plus, most of the text go to the log, not the display.

No. Grep the directory, it will be somewhere.

showopts is actually a grub token, not a kernel one
And splash might be a init token, not the kernel.

Interesting. Let me try… Wow! I love it!

There is only one snag: it gets erased when the tty activates. In systemv
mode there was a difference to the definition of that terminal so that it
didn’t erase:

/etc/inittab:


1:2345:respawn:/sbin/mingetty --noclear tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6

Have you seen anything to do that now? O:-)

If not, I can ask in the mail list.

In statistics, normal means that what happens oftener. So yes, it is normal
