Cobalt compatible distribution

I do realize the kernel is modified as part of Cobalt installation. This 
is certainly why only specific kernels are supported. Which is why I was 
looking for a distribution which shipped with a supported kernel.

I was neither expecting nor looking to distrowatch for a distribution 
which included Cobalt. All I was looking to distriwatch for was a 
distribution which shipped with a kernel version supported by Cobalt. I 
found none, which is why I went to the community.

In the absence of any such distribution that ships with a supported 
kernel, I will fall back to selecting a distribution whose kernel can 
easily be updated to a Cobalt supported kernel version. At the moment, 
Ubuntu seems a very likely source. If you would suggest a specific 
distribution and version I would be most appreciative.

Thank you for your assistance.

Some distros/desktop environments offer lower latency than others by the time you're all done, but that's really about it. LXDE/LXQt might give you better scores than let's say GNOME/KDE.
