how do I boot to a text console in 12.2?

lynn-32
In 12.1 I just type 3 at the prompt. In 12.2 I don't seem to have the
opportunity to type 3 anywhere.

Thanks,

in opensuse 12.2 the default bootloader probably changed for everybody
to grub2 (version 2), and that makes it necessary to go into the
editor like interface of grub2 during pre-boot time and add your
commandline kernel switch parameters there, which can also be added
temporarily for just the following boot attempt if I am not mistaken.
ctrl+x or F10 or whatever the help text says in there inside grub2
boots your added changed parameters then.

it seems a bit more complex or complicated in comparison to grub1 times.
consult the manpages or websites. good luck.

So much for making things _more_ user friendly, *not*.
Seems the programmers forgot about KISS.

They didn't forget about KISS, since they made several things easier to use
and I like most of GRUB2.

However, it seems there is a new fashion in the F/OSS scene to make some
things better with a rewrite and leave out well-proven features :-/

grub1 also made you go into edit mode by default. I'm not sure whether
it's an opensuse-specific patch or a config thing, but opensuse is the
only grub-based distro I know that lets you change the kernel command
line so easily. I liked it in fact, it makes phone troubleshooting
with inexperienced users a lot easier (they don't have to press their
way through unwieldly menus).

Anyway, if it's an opensuse patch, I'd bet they didn't have time to
port it to grub2 yet. If it isn't... I'd suggest they do :-)

Seems is a gross understatment. The differences between Grub Legacy and Grub2
are akin to the differences between IceWM and KDE4.

+1 +2 +4 +8 +16...

This amounts to a feature loss, so a bug would be the appropriate way to
react, if one hasn't already been filed. As long as Grub Legacy is available,
I won't be using Grub 2, making me an inappropriate person to file such a bug.

Granted I've not used it much, because on first exposures (via *buntu) I
found too little similarity and less convenience, definitely not easier to
use, KISS missing.

For sure, except for the "new" part. KDE4 was started when, 5 years ago? 6?

At the Grub2 menu press "e" for edit and look for the line beginning
with
linux /boot/vmlinuz-3.4.6-2.9-desktop
root=UUID=4b1660a7-c184-487b-a64e-03c346412da5

It's the 3rd line from the bottom. Add  a space and "3" after it.

Example

linux /boot/vmlinuz-3.4.6-2.9-desktop
root=UUID=4b1660a7-c184-487b-a64e-03c346412da5 3


After adding the number press F10.

Mmm, so, how do I boot to a text console in 12.2? Must I learn emacs to
be able to do it? Has anyone succeeded? Could anyone tell me how to do it?

Do you mean to run level 3? If so, then add a 3 to the boot options line for
Grub legacy. If Grub2, then see
http://www.if-not-true-then-false.com/2012/howto-change-runlevel-on-grub2/ for a
tutorial on how to edit the boot parameters when starting. You add the "3" to
the "linux" line.

runlevel 3 doesn't give you a pure text console.

I don't know what the OP means, text console = tty, or text console =
no graphics mode.

If it's the latter, you get it with vga=<n> with <n> a non-graphic[0] mode.

    Why don't people use LILO?

It's interface is still the same and it still works...

I can't answer for others. As for me WRT Grub Legacy:

1-Because of Lilo, I avoided Linux until I discovered distros that used Grub
and defaulted to it.

2-Kernel/initrd changes require "running" lilo before a reboot can use them.

3-Grub shell allows to manually boot from the Grub shell, crucially handy if
menu.lst is missing or otherwise problematic.

4-Interactive editing of initrd & kernel cmdline.

5-Chainloads NTLDR, IBM BM (at least in theory), other Grubs, & even Lilo.

6-Easily configurable & installable even though booted to another OS or media.

7-Needs no files in /etc to be able to function or configure.

It does on my 12 or 13 12.2 systems, though Grub2 is installed on none of
them. I rarely boot without a 3 on cmdline (usually via menu.lst).

vga= only works when KMS not active. When booting verbose (e.g.
splash=verbose, as opposed to silent, in which case I don't know what
happens, since I never boot with silent on cmdline) with vga= on cmdline but
not video=, vga= will be active only briefly, until KMS kicks in, after which
KMS will choose a mode based upon EDID. If you want ttys to do what vga= did
pre-KMS, you need e.g. video=1152x864@60, or whatever your own preferred mode
is. Since 11.3 all my kernel lines include both vga= and video=, except on a
few machines with video chips lacking KMS support.

On *buntu at least, if not openSUSE (I have Grub2 installed on none) and/or
Fedora and other Grub2 distros too, with Grub2 there is yet more complexity,
which I don't hope to explain beyond offering this bug URL:

Ah, yes, you're right. You need nomodeset too.

Hi
Sorry for not being clear. I did say that I 'just use to type 3' in an
earlier post so sorry for being badly written. English is not my first
language.

Yes. I want runlevel 3. Just like I get in 12.1 when I type 3 at the
grub prompt.

+1.  LILO is even still being developed/maintained.

Because they hate having to run it whenever they add a new kernel?
