=== Compile A Kernel ===

The first thing to understand is that each and every OS distribution has a set of very specific tools that can be used to build a custom kernel from the sources available. This article is about compiling a kernel on the Ubuntu System(s). What the author shall attempt to describe for you is information on how to build a custom kernel using the latest unmodified kernel sources from Kernel.org and Vanilla Kernel.

We had an OP who had gotten a little carried away with removing old kernels via Synaptic .. Yeah, you're well ahead of me on this one

Took a little while, and a couple of attempts.. But, this works.. As just as it was written, we had another OP who'd aborted an upgrade to Media after installing the RT kernel, they got his 'normal' kernel back as well. May help someone else

Linux performance: is Linux becoming just too slow and bloated?

Submitted by k4tz on Tue, 01/26/2010 - 11:56

This is an aspect of FOSS that is regaining some measure of interest: for years, it was considered that writing production-ready FOSS meant lean and mean software. However, recent events have shown that, in the case of the Linux kernel, this is no longer exactly true: performance is dropping slowly yet steadily.

How come?

While I agree with the need to purge the system of unused, outdated kernels to reduce bloat, with Synaptic and all, you may still miss out on a few of the kernel-related packages.

HOWTO: Install Nvidia drivers including DKMS module

Submitted by k4tz on Tue, 01/20/2009 - 10:54

Source: http://ubuntuforums.org/showthread.php?t=1036788

I figured out the last days how to correctly setup DKMS for newer Versions of the NVidia-Driver. In case you dont know, DKMS is a nifty little system that will ensure you dont run into trouble if you install a new kernel. Running a new Kernel requires ALL modules to be recompiled, and in the case of propietary drivers (ie drivers you dint install through apt-get) this task is left to you.
DKMS is there to automate this very task, you wont ever have to care for kernel-upgrades again.

Hello! This is an advanced guide for Linux power users who want the most out of their system on Ubuntu 8.10 (specifically the graphics processor) by getting fglrx (ATi driver) and or Mesa 7.3 release candidate 1 (Beta release) working on a custom kernel (I used upstream official linux kernel 2.6.28 stable with no snapshots or Andrew Norton's patches.)
