linux-lowlatency can't be installed in Flidas because it depends on linux-image-lowlatency which depends on linux-firmware and linux-firmware isn't in the repository. If I understand correctly, linux-firmware is not included because some of its code is proprietary. Is there a way of installing a lowlatency kernel without non-free firmware? I tried jxself's repository but it appears to include only the deblobbed generic kernel.

Well spotted. File it as a bug! :)

In general I have been reporting missing or broken packages as bugs. I asked about this in the forum because the package linux-firmware might be non-free, in which case its exclusion is not a bug. If it is non-free there is likely a libre replacement, and if so I'd like to know what it is so that I can specifically request it in the bug report and be able to install linux-lowlatency without having to wait for the official Flidas release.

Btw your avatar is the best.

It looks like linux-firmware is only a dependency of linux-image-lowlatency for Flidas. It wasn't for Belenos. Perhaps you could try installing one of the version-specific lowlatency images (i.e. linux-image-4.8.0-58-lowlatency). Those don't list the firmware package as a dependency. I haven't tried it myself, but I probably will over the weekend.

Thanks for the comment on the avatar. I've had him for years, but I like him! :D

I tried what I mentioned about last night and it booted up fine, with all the modules. Although, the behaviour of my laptop trackpad seems to have changed. Now the region on the RHS that does vertical scrolling has widened by about 3-4 times, which is really annoying.

Perhaps the driver has been updated in this newer version kernel? I might try loading the old module in, to see if I can revert it back.

Does the Linux-Libre kernel use low-latency? I thought it did... I'm trying to find that info.

Low-latency kernel is the default on my Belenos, I installed by the full size image.

What's the difference between normal and low-latency kernel?
