Have you looked at the KXStudio repos? They have a rt kernel that I have used successfully with Ubuntu 12.04 and 13.04 and it's really simple to install. They are currently moving from Ubuntu to Debian repos so their how-to in http://kxstudio.sourceforge.net/Repositories is broken, just look at these repos: https://launchpad.net/~kxstudio-team/+archive/kernel/

I compiled my own rt-kernel, using http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.48.tar.bz2 and its related rt patch, as in the tutorial that Jeremy posted. The kernel compiles and installs fine, but when I load it from grub, Mint load correctly, and then (before seeing anything on screen) my screen goes black. Nothing to do there, tried to use hotkeys to get a tty, restart, or shutdown, but had only to push the power button.update:1_ tried to install 3.10-2-rt-686-pae_3.10.7-1_i386.deb from http://packages.debian.org/jessie/linux-image-3.10-2-rt-686-pae, but it didn't like my initramfs-tools version (apparently too old for the new kernel) and installed without configuration so had to remove. See log:
dpkg: dependency problems prevent configuration of initramfs-tools:
linux-image-3.10-2-rt-686-pae (3.10.7-1) breaks initramfs-tools (<< 0.110~) and is unpacked but not configured.
Version of initramfs-tools to be configured is 0.103ubuntu0.7.
It's probably an nvidia driver-related issue, am I correct?
Will investigate further, please throw me suggestions if any,I might ask falkTX how he sees the rt-kernel for 13.04. I saw there is some working on Launchpad, but they are last modified sept. 2012 (?).
thank you!best,
M

Did you consider building your own kernel? I'm using self-built RT
kernels on Ubuntu 12.04 and that works great:
http://wiki.linuxaudio.org/wiki/system_configuration#build_your_own_real-time_kernel
And are you using rtirq?
Alessio Abogani stopped maintaining th RT kernels for Ubuntu quite a
while ago. You might want to ask falkTX about the possibilities of
offering a raring RT kernel.
Best,
Jeremy
Hey Jeremy!Yes, that's the other thing I will try now, good to know it works on 12.04.My pain in the a... is that I have to use nvidia drivers, and had troubles some time ago with them and rt-kernels.
Do you happen to know whether I need to patch nvidia support into the rt-kernel I build? (I guess so... just to be sure)thanks!best,
M
