Ubuntu Installation :: Freezes Up 30 Seconds Or So After A Successful Login?

Problem: Ubuntu freezes up 30 seconds or so after a successful login.

Background:I am running a Compaq Presario SR5030NX. It has had issues for a while with running Ubuntu properly. My computer suffers from this bug. I have managed to get the LiveCD running by adding the following to my boot parameters:

Code:
vga=792 i915.modeset=0
When I was running the LiveCD I found that it would freeze after about 30 seconds. I solved this problem by again changing the boot options. This time I:Press F6
Check noapic, nolapic, and pci=noacpi

I then proceeded to install Ubuntu.

My problem arose when Ubuntu did not modify grub.cfg to match the setting I needed in order to boot. I managed to modify in some of the settings correctly, I believe at least, but not all of them.

In its current state Ubuntu is able to boot, but freezes 30 seconds or so after a successful login. If I do not graphically login, I do still have access to VTY1-6. The machine does not freeze until a successful graphical login has been made.

Below is the relevant section of my grub.cfg:

Code:
menuentry "Ubuntu, Linux 2.6.31-14-generic" {
recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,2)
code....

On another note:
The liveCD I have been running for 6 months is BackTrack 3 Final. Which does not have this issue at all. I would wager a guess that BackTrack 4 does though as it is based off Ubuntu instead of Slax.
