i want know if GRUB2 is done 100% for yast and installation default on Opensuse 12.2

2

How can it be 100%? We are still at Beta 1. It’s usable as long as you know your way around.
Yes. It is the default for installation. You must ensure that you disable the images before running your installation.

I don’t think, its done 100% in YaST. I can only edit the current (?) boot configuration. No chance to configure a multiboot system with YaST. I have to do that manually by editing the configuration files directly.

When I did clean install of 12.2 Beta1, I told it to use grub2. It setup
my dual boot with no problem. I have 12.1 on seperate disk from 12.2,
and grub2 detected everything, included external disk with a Windows
partition. Don’t know what will happen if both OS’s are on same disk.

I installed 12.2 Beta1 with the images disabled and it picked up my 12.1 entries including failsafe.

If you do not see your entries open a konsole and type:

  • su - <followed by your password>
  • grub2-mkconfig -o /boot/grub2/grub.cfg

You should see the rest of your entries.

I see all entries in the boot menu. My other (12.1) installation got detected and added properly. That’s not the problem. But if I want to change a setting; let’s say add “nomodeset” to the 12.1 menu entry, I can’t do this using YaST.

I always use vim. you need to open konsole and type su - <password>

Next, you must open “grub.cfg” located in /boot/grub2 as the entries are located in grub.cfg.
But before opening and editing make a backup copy of grub.cfg by:

cd /boot/grub2
cp grub.cfg grub.cfg-backup

Check that the copy has been made. While you’re in the same directory open the “grub.cfg” file.

vim grub.cfg

Use the up/down arrow keys to navigate. Press " i " to input text.

When you’ve finished typing, press the “ESC” key, followed by " :wq! " (without the quotes). Look at the bottom of the file as this is where your commands appear.

FYI
:wq! means “write - quit - force to exit a read-only-file”. quit means exit file.

I know, how to use vi(m) and where and what /boot/grob2/grub.cfg is. But a lot of people do not know this and will not want to learn this, just to change a boot setting. For grub1 it was/is possible to configure these things with YaST; with a “Help” button and less chances to destroy the configuration file. My point is, that this missing YaST capability is a regression if openSUSE switches to grub2 as the default.

The Yast bootloader module is supposed to fully support grub2 before release according to the features page: openSUSE:Upcoming features - openSUSE

I have 5 distros on my PC and all distros are in grub2 from openSUSE 12.2. Developers did good work.

I’ve got three, all accessible, but graphics resolution screwed on the
pre-existing systems. Bug reported.

I installed 12.2 beta 2 from DVD this morning. The grub2 resolution was set somewhere around 1900x1400. My max is 1366x768. I couldn’t even read it at first boot:O

13

For my latest install, grub says “Cannot display this video mode”, so I don’t see any kind of menu (but it does boot into the system).

The solution is to change the line “GRUB_TERMINAL=gfxterm” to “GRUB_TERMINAL=console”.

Make that change in “/etc/default/grub” and then regenerate “grub.cfg” (or, alternatively, also make the same change in “/boot/grub2/grub.cfg”.

In any case, grub2 for opensuse is still a work in progress.

or try following:

go to file: /etc/default/grub
search for: GRUB_GFXMODE=auto

change it to: GRUB_GFXMODE=1024x768
or any other resolution you want

save file and run: grub2-mkconfig -o /boot/grub2/grub.cfg
as root

Grub detect the highes resolution of you videocard but doesn’t look to what the monitor can do…
