I'm on Kubuntu 12.04 with lts-raring HWE stack. I'm running kernel 126.96.36.199.18 low latency. A recent update replaced my low latency kernel with a slightly newer (188.8.131.52) 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@example.com> 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: 184.108.40.206.18 Candidate: 220.127.116.11.18 Version table: *** 18.104.22.168.18 0 500 http://ppa.launchpad.net/kxstudio-team/kernel/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status 22.214.171.124.43 0 500 http://us.archive.ubuntu.com/ubuntu/ precise-updates/universe amd64 Packages 500 http://security.ubuntu.com/ubuntu/ precise-security/universe amd64 Packages 126.96.36.199.20 0 500 http://us.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages
