[SOLVED]Multiple Kernels

Nerd King · 2010-03-25 17:12:16

Just made the move on my laptop from Ubuntu to Arch so excuse me for the stupid question. In Ubuntu I can just grab Debs from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and install them, and hey presto, new kernel installed and grub shows it along with existing ones. Now I've figured out that the AUR contains kernels, which is awesome, but will installation add the extra options to GRUB and let me choose between kernels or will I be stuck with whatever I choose (so if it hoses the system I'm screwed)? I'm using Grub 1 if that helps, not Grub 2 as it's slow.

You have to do everything manually. Having package X fiddle with configuration files part of package Y is against Arch policies.

That is Grub's job. Grub provides the boot menu, in-between the BIOS screen and the kernel loading.

I'm just curious as to why you think it's slow?

No worries, manual it is. But can I assume that if I have some modicum of brainpower I should be able to choose between them in the grub menu and they'll both work fine?

Brebs.. Grub2 on my ubuntu install took about 5 or 6 seconds to appear, compared to almost instantaneous for grub1. Maybe it's a crappy ubuntu build but that's my experience.

Depends on exactly how much your modicum of brainpower amounts to....

But yes, its dirt-easy. menu.lst for the win

It fairly easy. As ngoonee said you edit menu.lst, I mostly just edit the fallback option when I only test the kernel, then when I get it to work properly I changed from ARCH to ck.

And don't forget that after you install the new kernel you have to rebuild your graphic drivers if you wish to use X on a new kernel.

Well if you use gfxterm/vbe/whatever it is that makes grub2 high-res, then it's slow. So I never enabled that in the config, and it's just as speedy as legacy grub for me.

Does that apply only to proprietary drivers or to open ones too? (I'm on open ATI drivers)

Applies to any out-of-tree kernel driver.

Fair enough. Let's see if I can do this without wrecking anything!

Thanks for everyone's help, I now have the 2.6.33-rt-ice kernel working beautifully, you've all been wonderful, as have the people whos threads I searched
