12. The NEED for SPEED – Speeding up your N900
These are recommended applications to help you speed up the response, movement, and transitions to your N900.
IMO, this is how the unit should have been released from the beginning, however, there are 2 factors with this that are in play:
Nokia is more conservative on this
Lucky for us this is open-source and we have an UBER community to create these fixes for us to use!
Be sure that you have installed the EXTRAS-DEVEL and EXTRAS-TESTING catalogs.
The applications to install are:
Black Plastic (additional theme packs are not required)
Enhanced Linux Kernel for power users
QCPUFreq
Transition Control
Swappolube
Black Plastic – This is a basic theme pack that will make an immediate difference in the over-all appearance and styles of transitions to your N900.  You can adjust all these settings and transitions by going to:  settings/Plastic Theme Setup
Enhanced Linux Kernel for power users – You do not have to do anything with this directly, though if you search this forum, you may come across some basic code for loading certain frequencies that you want.  To make this simple, just use the QCPUFreq. It will give you the ability to over-clock your device up to 1.15ghz
QCPUFreq – This is an EASY way to change the over-clocking frequency to your device with a simple slide bar.  Don’t bother with the SmartReflex, just use the slider-bar.  Before you can over-clock above the 600mhz, you will have to tap the menu/enable overclocking.  There will be a pop-up about warranty stuff, this is protection for the developer.  I have multiple units OC’d since they started doing it around 3/2010, no issues on any of them….UNLESS SPEED IS AN ISSUE!  NOTE: EVERY TIME YOUR DEVICE IS RESTARTED, YOU WILL HAVE TO REDO THE OVER-CLOCKING.
Transition Control – This allows you to change how fast all the transitions are.  You can change the numbers to anything you want.  I have set all of the options to 5.  I have heard others at 10, and others at 0.  If you really don’t care much about having to see a looong sweeping effects, and would like it to just be “blip”, then 5 or 0 will do it! 
Swappolube – This will allow a complete “lube-job” for your N900.  If you tap “proposed/apply/store” then it will give the best option to your devices settings, and make it so that when you reboot your device, or change the battery, you will not have to reset this again. Details can be seen in a post by CPitchford @ post: /t5/Maemo-Devices/Make-your-N900-faster-with-Swappolube/m-p/765938#M19220 )
To install them:
Open xterm
sudo gainroot
apt-get install black-plastic-theme kernel-power-flasher qcpufreq transitioncontrol swappolube
Or, if you want to install them all separately:
apt-get install black-plastic-theme
apt-get install kernel-power-flasher
apt-get install qcpufreq
apt-get install transitioncontrol
apt-get install swappolube
TO GO TO ORIGINAL FACTORY SETTINGS AND REVERSE ALL SETTINGS CHANGES:
All you have to do is uninstall all of these.  All the factory settings will restore automatically.
Open xterm
apt-get remove black-plastic-theme
apt-get remove kernel-power-flasher
apt-get remove qcpufreq
apt-get remove transitioncontrol
apt-get remove swappolube
or one long command:
apt-get remove black-plastic-theme kernel-power-flasher qcpufreq transitioncontrol swappolube
