I just got it working. The script was executable; that wasn't the problem. The other thread suggests that you only need to disable the odd numbered CPUs (i.e. the hyperthreaded ones). But for some reason I need to disable all CPUs 1 through 7, not just the odd numbered ones. Once I did that I got rid of the video stuttering after suspend. Woo hoo!
Now I just need a fix for my compiz getting disabled in nvidia mode after my monitors power off. I'll post if I figure that out.
Great machine. Thanks for your help! - Greg
Hello all-
I'm considering purchasing a ThinkPad W520 and would like to know if anyone has gotten the discrete graphics card with the Nvidia driver working in 64 bit linux without disabling ACPI. If so, I'd like to know the following version numbers:
1. BIOS
2. Ubuntu
3. Kernel
4. Nvidia driver
Also, I'd like to know if it's working with problems that can be "lived with"- that is, they don't prevent the computer from operating. (ie, not returning from suspend or hibernate, or choppy playback after suspend, etc.)
If you could help, I'd much appreciate it. Thanks!

Mine is working just fine, though I haven't tested extensively. Let me know if there's a particular problem you're worried about. I haven't manually disabled any ACPI stuff. How do I know if that's running? Here's what I have:
Ubuntu 11.04 - 64 bit
W520 - Quadro 1000M, quad core
BIOS - not sure, just updated to latest version a week ago
NVidia driver - 270.41.06
Kernel - 2.6.38-8-generic
I can use either discrete or integrated graphics (not both yet). I have suspend and hibernate working just fine. Occasionally gtk-window-decorator stops running - not sure why - but I just restart it. The battery meter seems to have problems with its predictions. Overall pretty minor.

Just got 3D working today.
1. BIOS 1.25
2. Ubuntu 11.10 64-bit
3. Kernel 3.0.0-12-generic
4. nvidia 280.13
Changed the optimus setting to discrete in the BIOS and now 3D works. I haven't made any other changes in the BIOS. Unity was working just fine before that, I just couldn't run any openGL programs. My W520 has the quadro 1000m.
Using Bumblebee and it works great on my w520! -> http://sachithdhanushka.blogspot.com...l#comment-form
