Getting things to work

It was not easy make practically everything work under Ubuntu. Installing drivers from source code, configuring and recompiling the kernel was a must, the hours spent searching forums with Google I'd rather not count:)

I'll be honest: if you are completely new to Linux, getting the machine fully functional will be difficult, be ready to learn a lot. Beleive me, it will be worth it!

now onto some serious business! Below you'll find some information that might help you how to get things working - I'll try to expand this with more in-depth descriptions, please be patient.

CPU Freq Scaling
None
Touchpad
None
Ethernet
None
X11 3D acceleration
I compiled the i915 driver as a kernel module and load it at each startup, by putting ''i915'' into /etc/modules
Dual - Monitor Display
Got it working after some Google Search, I have separate Xorg.conf files for this use - have to restart X-Server
PCMCIA slot
None
Audio
Don't compile any ALSA modules into the kernel! Just ALSA support, then download and install the latest ALSA driver. It works with out-of-the-box though with theUbuntu Edgy Eft live CD!
USB
Had to blacklist the ehci-hcd module otherwise no USB2 devices work (put 'blacklist ehci_hcd' into /etc/modules.d/blacklist). If EHCI-HCD is compiled into your kernel, well, then recompile it...Edgy Eft Live CD still has the same problem.
Modem
Probably will never try...
Special Keys: Fn + ???
None
Suspend to RAM
None
Wifi
No Intel Firmware or driver enabled in kernel config, both firmware and module source code was downloaded from the net

Some useful information (download links!)

Kernel configuration file
You can download it from here
XServer Config File
For single monitor output (the LCD screen): xorg.conf
For Dual Monitor output, with different resolutions on the external monitor and the LCD: Xorg.conf.dual
