    Which Kernel For 8.04?

    I just recently upgraded from 7.10. During that process I chose to keep my original grub list where I specified to use kernel 2.6.20-16 which is what I used for 7.10.

    Question - What kernel should I be using for 8.04? Am I loosing any functionality by not using the latest kernel (my PC is 7 years old).

    Thanks!

    Re: Which Kernel For 8.04?

    Open a console and type:
    Code:
    uname -a
    You'll get an output that looks like this:
    Linux laptop 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
    laptop is my 'host' name, so yours will be different. 2.6.24.16-generic is the kernel I'm using (for this current booted session).

        That kernel indicates you are running Feisty, not Hardy!

          Well, I was wondering if that were the case. Next question - how do I resolve this? Can I just install the correct Kernel? If so, how?

            Let's take a look at your /boot/grub/menu.lst file. Open a console and type:
            Code:
            cat /boot/grub/menu.lst
            Copy and paste in your reply.

                Re: Which Kernel For 8.04?

                Okay. First, a correction to my observation: you are running Gutsy here, not Feisty. Should have read your initial post more carefully. :P

                Open a console and type:
                Code:
                cd /boot && ls -l vml*
                You should get the following:
                -rw-r--r-- 1 root root 1909528 2008-03-12 17:43 vmlinuz-2.6.24-12-generic
                -rw-r--r-- 1 root root 1911128 2008-04-07 20:01 vmlinuz-2.6.24-15-generic
                -rw-r--r-- 1 root root 1904248 2008-04-10 08:51 vmlinuz-2.6.24-16-generic
                All you need to do is to change:

                2.6.20-16 to 2.6.24-16
                2.6.22-14 to 2.6.24-15
                2.6.20-15 to 2.6.24-12

                in each of the stanzas. I would also change the title lines to reflect Kubuntu 8.04 as well.

                This file of course, has to be edited as root. And before you do, make a backup first!

                  Re: Which Kernel For 8.04?

                  This is what I get:

                  mrmsu@closet:~$ cd /boot && ls -l vml*
                  -rw-r--r-- 1 root root 1745100 2007-04-15 04:07 vmlinuz-2.6.20-15-generic

                  mrmsu@closet:/boot$
                  Which does not exactly match what you have.

                  Just to clarify - I'm to make these changes in my grub menu. Correct? And, if so, does this mean that the latest kernel is installed on my machine (via the upgrade to 8.04) but I'm just not using it?

                  Thanks!

                      Yes. If you repost your menu.lst, I'll look it over to see if 'all is right.'
