Lenovo T400 Suspend / Hibernate / Resume Problems

[jan.]

I got resume/suspend working by simply disabling Bluetooth in BIOS...

Can you confirm this through several suspend- or hibernate-resume cycles?

You might have the same bug that I have.

If you have a single running the 64bit version and it reboots when you resume
you might want to follow this bug

Confirming this bug on a Lenovo Thinkpad T500. Your script works, thanks!

Afty, a number of other packages (acpi-support, powermanagement-interface, ubuntu-desktop) depend on vbetool, so I'm a little reluctant to remove it.

At any rate, petri's script works for me. The only problem is that while it's waiting, I get a string of "bad: sheduling for the idle thread" errors -- but then it suspends / hibernates just fine.

Hello,
I don't use ubuntu but I also got a new T400 recently.
I am not quite sure what happen to this specific case but
I am sure that a large amount of T400 have the problem of
suspending or freezing after "Sleep", "Hibernation", and "Restart". Some of them even cannot be shutdown and turned on normally.
I believe that this is a hardware problem.

If you can't find any solution using tweak or other software configuration, just call Lenovo Support and have your motherboard changed. The problem will be solved.

Good luck

Does that mean it is the hardware problem? I have my computer hibernate, and now Ubuntu can NOT boot!

Well, I believe there is indeed a concurrency problem, since the script petri0 posted is working out for me.

I did not have any hardware related boot problems. I am using my T400 with all devices enabled and integrated graphics instead of discrete ATI.

Hibernation aside, what kind of performance are you guys getting out of your X4500-equipped Thinkpads? I have had Dell E6500 with this card for a week, and Compiz was so slow that machine was barely usable. I am hoping this was Dell-only issue and X4500-equipped Thinkpads work fine.

What's your glxgears score?

What's your glxgears score?

My T400 with the integrated graphics gets around 720 fps on glxgears. Compiz runs reasonably well on this machine.

Petri's script worked for me on my T400, and my system comes out of suspend now, but my sound isn't working after a resume. I get no sound from applications like Rhythmbox or Flash Player (Youtube, etc.), either through the speakers or the headphone port.

Is anyone else having this problem?

Edit: Restarting pulseaudio after resume fixes the problem.
