Sony vaio tx3xp
From ArchWiki
This should also work for all other TX-series notebooks from Sony (i.e. TX1, TX2, TX3, TX5) - main difference is the speed of the cpu.

Configuring Xorg
The hardest part of setting up arch on the tx3xp is getting the widescreen resolution right. But once you know how it's fairly straightforward. The following xorg.conf will has been tested with xorg 1.6+ with hotplugging enabled. If you don't want to use hotplugging, you will have to define kbd options for your keyboard and mouse.
Section "Monitor" Identifier "Monitor0" ModeLine "1366x768" 88.03 1366 1424 1704 1816 768 770 782 808 EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" SubSection "Display" Modes "1366x768" Depth 24 EndSubSection EndSection
Installing the intel driver
pacman -S xf86-video-intel
Again if you are not using hotplugging you will have to set your driver as intel in your xorg.conf.
If you are using hotplugging all that is left is to add hal to your daemons line in rc.conf and test X with the startx command, making sure everything is ok, before modifying /etc/inittab to start the GUI on boot. More info on configuring hotplugging, and getting your keymap correct is here.[1]
Wireless
You will need the iwlwifi drivers for the ipw3945 chipset card in this laptop. The guide to installing them is here[2]
A very decent network manager is wicd[3]. It manages the ethernet as well as wireless connections.
Power Management
For CPU frequency scaling see this article[4]
Add the sonypi module to enable the battery monitor in the KDE control centre.
Notes
I have installed the 915resolution package but I am not using it, so I do not think you need it, but it's worth a try if you are having trouble.
