Install and enable "realtime" kernel(SOLVED)

Postby Mr. Lumbergh » 2019-10-08 05:38

I have a multiboot system with Buster and another distro whose GRUB2 is the master for the system. The other distro allows the installation of several kernels that I can choose at the GRUB menu, but I've tried installing the most recent RT version available in Buster, updating GRUB, and it doesn't show the RT as an option. just the vanilla 4.19 and its debug. Is there a way I can set up Buster to allow me to choose the vanilla or RT at boot, and what tricks if any are needed to get this to show up in GRUB?

You will need to update grub from the OS controlling it, reboot and it should show the new kernels.

What system did you install the rt kernel on, and how did you install it? Did you give sudo update-grub in debian buster?

I did. I booted back over to the other distro and ran
update grub2
from a terminal as root. It didn't show, so I'm curious if there's something else I may have missed.

It was on Debian 10. I used Synaptic since I wasn't sure of the exact name of the RT kernel to call it from the command line; I searched for "kernel" to get the list. I don't have GRUB installed in Debian since it had already been configured from the other distro.

Update: I'm on the RT kernel right now. There was a recent batch of updates on the other distro that I think also included GRUB. The menu when I booted back over to Debian a few minutes ago had a slider on the side this time, and I could select the 5.2.0_RT from the menu.
Thanks for your time.
