    You might also be interested in ulatencyd. It’s a daemon that controls how the kernel spends it’s resources. I’m using it with the stock Ubuntu 10.10 kernel (2.6.35-25-generic) with good results.

  2. Note that by doing things this way, you miss out on all of the kernel patches that stock Debian / Ubuntu kernels include. It may be better to start with one of those source packages and apply the patches you want, rather than starting with a stock kernel.org tree.

    @Tristan *nod* I did consider that. I’d like to see what gets patched, I’ll probably look at that today and hopefully I’ll actually understand what those patches do. I guess in such a high-profile package they will at least be well documented with references to bugs, etc :)

    I’m curious as to why you think Unity is a better underlying technology than Gnome Shell. Are you actually planning a blog post for this? Will Debian ever get Unity packages?

    Thanks for this little tutorial. I am trying to become a power user of linux, and this little guide is helping me. Thanks again for it.

    Thank you for writing this down. I’ve built a freebsd kernel before, it’s easy, but never built a working linux kernel. 2.6.38 is building right now, i think it’s going to work. THANK YOU.

    […] I haven’t bothered with custom kernels in a long time. I think the last time I ran a custom kernel on my own machine was in 2006. There was a time where I would just read kernel code and change random things just to see what would happen, I’m definitely not that brave anymore. More here […]
