I'm on Kubuntu 12.04 with lts-raring HWE stack. I'm running kernel 3.8.0.30.18 low latency. A recent update replaced my low latency kernel with a slightly newer (3.8.0.31) generic kernel. I wish to prevent this and to use only the low latency kernels. How would I do this?
I believe this information is required:
$ dpkg -s kxstudio-kernel-lowlatency
Package: kxstudio-kernel-lowlatency
Status: install ok installed
Priority: optional
Section: metapackages
Installed-Size: 26
Maintainer: falkTX <[email protected]>
Architecture: all
Source: kxstudio-kernel
Version: 2.4~precise1
Depends: linux-lowlatency, linux-image-lowlatency, linux-headers-lowlatency
Description: The KXStudio kernels - Low-Latency
This is a metapackage that provides the lowlatency kernel
I also wish to know exactly how to use apt-cache policy to verify that the installation candidates (for any kernel) are correct. The command below would apparently not show me when a generic kernel might supersede a low latency kernel.
$ apt-cache policy linux-lowlatency
linux-lowlatency:
Installed: 3.8.0.30.18
