I just finished compiling the newest 2.6.16 kernel from kernel.org and I am getting much better performance. In what follows, I will show you how to compile and configure the latest kernel. You do not need to use the 2.6.16 kernel but it is the first kernel of the release kernel and performance patches are only made for these releases. (
ex: 2.6.16, 2.6.17
NOT 2.6.16.20) Feel free to compile a kernel besides the first release cycle kernel. You do
not need the patch and you can configure the kernel for maxium speed in xconfig. A tutorial to optimize the kernel you are building can be found
here.
Before you begin, you will need to get a kernel
Download the 2.6.16 kernel and it's performance patch:
The 2.6.16 kernel
Latest Kernel Patch Don't apply the patch if you are compiling a kernel other then 2.6.16 otherwise the kernel will
not compile.
Check out kernel.org for the latest stable/release canidate kernel.
1. Install needed utilities to configure the kernel
2. Now we are going to move the kernel and unpack it.
3. Now we are going to move to /usr/src
4. Now unpack it:
5. Rename the folder: ONLY needed for 2.6.16 kernel ! You don't need to do this.
6. Now we are going to remove the link to the linux directory:
7. Make a new link to the new kernel:
8. Move to the Linux directory:
9. Make yourself root:
10. Apply the performance patch: Don't use if you are not patching the 2.6.16 kernel !
11. Now we are going to import your current kernel configuration:
12. Now import it: Make sure to replace the kernel version in this following command from the one from uname -r.
13.Configure the kernel:
Here are some performance tips from
this thread.
Note: Not all the options will be the same in newer kernels.
14. Let's build the kernel: Make sure that you are in /usr/src/linux with full root access. Make sure that you are. This will build a debian file that you can install.
Now, in terminal do the following:
Note: You can replace "ck12" with anything you want. Like "k7" or "686."
15. Install the .deb fine in /usr/src. In terminal do
Now reboot and you will have a much faster system !

How I learned to do this:
2.6.14 Vanilla Kernel I based my tutorial on this thread. Thank you for writing this tutorial RubenGonc !
And I also learned some stuff from
this thread
-------------------------------------------------------------------------
Troubleshooting:
Q: My Wifi Doesn't work !
A:To get wifi working, compile the new ndiswrapper from source. Follow the
tutorial.
Q: When I reboot I get Grub Error 22 ! WTF ???
A: You may have missed a step or messed something up. When it says Grub Loading..... press esc and you will be able to boot with another kernel. Then you should go into synaptic and uninstall the broken kernel and then reompile it.
--------------------------------------------------------------------------------
Q: How can I get fglrx and DRI working on my new kernel ?
A: Type this in terminal:
Reboot and if that does not work, make sure fglrx is in the Driver section.
---------------------------------------------------------------------------------
Q: I need kernel headers for my custom kernel.
A: I updated the howto and edited the last step to build a kernel image, kernel module image, and kernel headers. Thank you to tseliot for his kernel thread because I found the command there. You can view the thread
here.
------------------------------------------------------------------------------------
Q: I want to optimize my kernel ! What do I select ???
A: I just wrote
this tutorial on how to configure your kernel for enhanced performance. I hope
it helps.
----------------------------------------------------------------------------------------
Q: Why did you write this tutorial ?
A: I wrote this tutorial to help give back to the Ubuntu community. I've had such a good expericence with ubuntu that I want to help others. This community is great
