Ubuntu Studio: How to Install generic kernel properly and make it boot by default?

  • 772

I really like Ubuntu Studio and I enjoy the look, feel, and functionality along with the expanded capabilities of the the low latency kernel.

However I'm mostly a coder, and I like to have a lot of things open at once, and sometimes this can be really bad with a low latency kernel, so I decided to install the generic kernel to boot into when I'm not doing something like design or game development. I installed it like this:

sudo apt install linux-image-4.15.0-34-generic

I was able to but into it, however my 2k widescreen monitor isn't recognized in the settings when I boot to the generic kernel. How to I even begin to solve this problem without messing with the working low latency install?

UPDATE: it appears that all networking is down too.

UPDATE 2:

I was able to access more settings in nvidia x-server settings and the default display changed to my external monitor (the internal display was no longer recognized...) by installing 4.15.0-38 and the following packages:

linux-headers-4.15.0-38-generic
linux-modules-4.15.0-38-generic
linux-headers-4.15.0-38

I feel like this is the right direction, but what other packages will I need and is there a tool that makes this easier?

    Okay, I figured it out:

    You should be able to install one package:

    sudo apt install linux-generic

    Reboot and select advanced options and select the generic kernel.

    To make sure you're in the generic kernel once you verify everything is working:

    uname -r

    Should return X.X.X.X-generic where the X's are the (newest) kernel version number.

    Also you might want it to boot into generic by default, in which case you would edit the grub configuration file:

    sudo vim /etc/default/grub

    (replace vim with your choice of text editor)

    If it exists, replace the line that starts with GRUB_DEFAULT= with:

    # Make the latest generic kernel the default
release=$(linux-version list | grep -e '-generic$' | sort -V | tail -n1)
GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux $release"

    Finally, run this command to update the grub configuration: 

    sudo update-grub
