Feature changed by: Jan Engelhardt (jengelh) Feature #309840, revision 7 Title: Supress verbose messages after Grub
openSUSE-11.3: Unconfirmed Priority Requester: Important
Requested by: Anshul Jain (anshuljain)
Description: In the current bootsplash scenario, after we select the kernel version (or by default starts to boot with the only available kernel), it gives a brief 3-4 second verbose message on the screen.. something on the lines of "Uncompressing Kernel...<and the kernel options parameters>". It then proceeds to the bootsplash screen of openSUSE that we're all familiar with. This is elegantly supressed under Ubuntu through a patch called quiet.diff. I've added this patch to the grub SRPM and successfully built and installed it on my laptop (its available in my OBS at :- http://download.opensuse.org/repositories/home:/anshuljain/openSUSE_11.2_Upd...). I'd appreciate if the official maintainer of Grub can add this patch so that the boot can be a lot more elegant than what it is right now.
Discussion: #1: Jan Engelhardt (jengelh) (2010-06-15 10:45:19) Ubuntu, eh? I don't see any Uncompressing message: http://picpaste.de/nouncompressing.png If you go by the "elegant" argument, I have to say: activate bootsplash.
#2: Anshul Jain (anshuljain) (2010-06-15 13:01:31) Firstly, my apologies...it isn't the "Uncompressing" message but the first set of messages from the top in your pic (its not available now...) Secondly, with this patch+bootsplash activated (yes I have bootsplash activated), there are no verbose messages on the screen. While this may be trivial to you, it is an annoyance to many... including myself. I can see the condescension on this being an Ubuntu patch from your first statement. Just because it comes from Ubuntu, doesn't mean that it is needs any scorn. They have some good ideas as well...and there's no harm in picking the good bits to benefit openSUSE.

#3: Bruno Friedmann (bruno_friedmann) (2010-06-20 09:38:59) Hi Anshul Jain, Can you explain if your patch leave us choice ( something important here ) to have verbose message at boot ? From what I've seen on the lastest ubuntu, there's no Esc key that permit to see what's happen during system initialization even if it start with bootsplash. I need this choice !
#4: Ivo Anjo (knuckles) (2010-06-20 10:39:01) I think the possibility to have a silent grub is very important. End users should not have to see cryptic text unless they want to -- all debug info (and that *is* debug info) should be hidden by default. I have a macbook with opensuse and the current boot sequence is not very pretty because it goes EFI firmware -> black screen (bios starting) -> grub writes some crap -> bootsplash finally kicks in. I think this patch suffers from problems pointed out by this post in the ubuntu forums http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=742355 that proposes another, better patch for this.
#5: Anshul Jain (anshuljain) (2010-06-20 11:01:05) Bruno, You can still see all of the messages during bootsplash. This patch *does not* touch the bootsplash sequence. It merely touches the Grub. I've tested this on Opensuse and also Mandriva...works like a charm. Ivo, From what I see...the patch mentioned in the link you've posted and the one I'm proposing are the same, AFAIK.
