i installed Fedora 6 and the following worked for me. Im sure a similar process would work on Ubuntu but the paths to the scripts mentioned would be different…

1) change run level to 5 to load X server
# vi /etc/inittab
id:5:initdefault:

2) install the popular 915resolution Bios hack, search in google for it if you dont have YUM installed.
# yum install 915resolution

3) modify your monitor settings, i included all my settings which includes my irrelevant keybrd settings
# vi /etc/X11/xorg.conf

4) see what shitty monitor modes are available
# 915resolution -l
Intel 800/900 Series VBIOS Hack : version 0.5.2
Chipset: 945GM
BIOS: TYPE 1
Mode Table Offset: $C0000 + $269
Mode Table Entries: 36

Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 24 bits/pixel

5) choose a shitty mode and hack it everytime computer boots
->add this line
# vi /etc/rc.d/rc.local
/usr/sbin/915resolution 34 1440 900 24

6) if you want you can now see that mode 34 is now hacked.
# 915resolution -l
Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1440×900, 24 bits/pixel

7) reboot and it should load in perfect pixelation yumminess…
# reboot

ctrl-alt-F1 (to get terminal)
dpkg-reconfigure xserver-xorg
(here I basically used the defaults – 1440×900 – also chose medium for monitor config and set freq to 1440×900@100Hz or MHz – whatever)
sudo killall gdm
sudo gdm

and up it came. Then I installed it to the hard drive. The issue I’m dealing with now is getting the wireless card to work.
