    Publish new Kernel in Grub (1.99) Menu

    Hi,

    I installed Ubuntu Server 12.04 LTS and configured a Software-RAID during setup (md) to use both of my SSDs.

    Grub says it is version 1.99. Now I installed the new kernel to fix TRIM-support and support for my graphics card. I followed this guide: http://www.upubuntu.com/2013/04/inst...el-386-in.html and ran

    Code:
    sudo update-grub
    but the entries won't show up. In the grub.cfg I can find all entries I want.

    What do I need to do to make the kernel bootable? Manual editing in Grub did not help.

    Thanks for help.

    Re: Publish new Kernel in Grub (1.99) Menu

    First you say the entries don't show up in the boot menu, and then that in grub.cfg there are. grub.cfg is what is used for the boot menu. If an entry is there, it should show up.

    Since this was a manual kernel install I'm not sure you need to update the initramfs with something like:
    Code:
    sudo update-initramfs -u
    Or if that doesn't work, try something like:
    Code:
    sudo update-initramfs -k all -u
    In depends how the kernel is installed with the script they prepared, it might not make the initrd file, or something similar.

    Otherwise if the script did all the necesary, update-grub would have picked up the kernel and created an entry for it in grub.cfg and the grub menu.

    You understand that these kernel are not oficial so you are doing this on your own risk.

    Re: Publish new Kernel in Grub (1.99) Menu

    Nothing worked.

    This is my grub.cfg, but really, only the 3.5-Kernel entries show up as right after installation. Maybe it is related to the Software-RAID? I know that I do this on my own risk, but I have no choice. After the grub menu the screen remains black, only access via SSH works and TRIM is not supported for Software-RAID.

    Any other idea?

    No ideas really. Maybe they didn't create the kernel good so that it can work on mdadm?

    That's the problem with unofficial kernels, you never know what should or shouldn't work. Maybe you can try contacting the author, ealving a comment on that website, etc.

    The kernel is downloaded from http://kernel.ubuntu.com. You think they don't do their kernels correctly? I can not really imagine

    Re: Publish new Kernel in Grub (1.99) Menu

    The link you said you used in your first post makes no reference to ubuntu.com. The wget link is of dropbox, so you download what someone put in dropbox not from ubuntu.com, and the website www.upubuntu.com is not the same as the official ubuntu.com as far as I know.

    That's why I thought it's a kernel someone did before ubuntu releases it officially for your version. They will probably not release it at all. Otherwise you could have upgraded it from the repos, without downloading it yourself. 12.04 comes with 3.2.0 and it's still at 3.2.0 as far as I know, not even at 3.5.0.

    You are talking about kernel 3.8 so I have no clue how compatible it is even if you download it from ubuntu.com.

    Re: Publish new Kernel in Grub (1.99) Menu

    Ok, that is confusing. Kernel 3.5 is the standard in 12.04 LTS.

    Re: Publish new Kernel in Grub (1.99) Menu

    No, 3.5.0 is standard in 12.10.

    I think with the latest updates (since 12.04 is LTS and will have long support) they might have issued 3.5 for 12.04, but it definitely came with 3.2 by default.

    In any case, as far as I can understand the wiki kernel.ubuntu.com it seems only for developers and contributors. I'm not sure if they even recommend 3.8.6 for testing. You might try one of the 3.8.0 options, but 3.8.6 seems really too new and still in very early phase of development.

    You could probably google around for the correct full procedure to install 3.8.0 manually and how to insert it into grub.
