[Bug 471458] Re: Live CD / Desktop freezes on boot. NVIDIA Problem?

 

I solved the problem! The issue wasn't with the NVIDIA driver at all. My
FIC KT800 motherboard contains VIA chips, which are buggy with Ubuntu.
To get it to work, I would have to turn off ACPI in my bios since the
"acpi=off" parameter wouldn't do anything at boot time. The 9.10 Live
CD, and the Alternate Install CD, load ACPI as a Runlevel 2 3 4 and 5
script. This was what caused my system to hang during normal boot. Of
course, recovery mode has a Runlevel of S which doesn't run the ACPI
script.

To remedy the issue, I went into /etc/rc.2 from Recovery mode and
renamed "S99acpi-support" to "K99acpi-support" and that fixed things.
Now I also renamed "S99laptop-mode" and "S99onedemand" just to be sure,
and have since not named them back. I'm sure if I do, everything would
work still as long as "acpi-support" is not loaded. I don't even know
why "S99laptop-mode" script is in there since I'm running Ubuntu on a
Desktop!

But in all fairness, and where criticism is due, why would an Alternate
Installer, install the ACPI script, when at least 15% of the people
trying Ubuntu have a buggy chipset that cause it to crash with ACPI? I
thought the whole point of the Alternate Installer was to allow people
to install the system with safe drivers? I would hope Ubuntu would omit
the ACPI script from the Alternate Install in the future. I'm sure it
would solve have of the help requests in the forums.

Please let me know if there is any further info I can provide for this
resolution.
