[SOLVED] Ubuntu 10, ThinkPad X200. Sleep broken

i-SnipeZ · **Posted:** Thu Feb 03, 2011 3:09 pm

I'm stumped here. It used to work fine, but now I can't seem to get it to work.

When I close the lid, or try to put it to sleep from the menu, it appears to work fine, then, the checklist disappears and it goes straight to my screensaver.

Any ideas?

Try forcing suspend-to-ram directly:

Code:

echo mem > /sys/power/state

If it does work, then the problem is most likely caused by something Ubuntu-GUI-specific.

It came up with a whole list of things that failed to suspend, flashed, and just left me at the desktop again.

Try to get this "whole list of things" from "dmesg" output (pastebin it / post it here). You may also try pm-utils, namely pm-suspend.

Also, knowing what version of Ubuntu you're using would be helpful. Are you using 10.04 or 10.10?

10.10. I'll post the list of things shortly...

Sorry it's taken me this long, but here's what I'm assuming you want, I'm not a total linux noob, but, I'm still learning quite a bit:

Try disabling VTd in the BIOS.

It was, and has been, disabled. Re-enabling it doesn't effect the outcome when I try to suspend.

Huh. I only suggested that since I'd seen issues with it in the past.

Not that it helps, but the X200 definitely functions flawlessly under Debian 6.0 and Ubuntu 10.04 -- so I'd guess it's a regression from 10.04 -> 10.10.

A few more things to try:

- disable wireless prior to suspend
- switch ttys to a non-X one before suspend
- disable TPM via the BIOS

Also, I assume you're running the latest BIOS version?

Yes I am. It was working fine, however, I remember a kernel update around when it stopped suspending. So I may have to revert somehow?

Oh dear. You got Ubuntud. Well -- if it was a kernel update that broke it, there's not much that you can do short of tracking down an older version of the package or switching to the mainline PPA. I'd recommend the latter, as I'd suspect it's less likely to break userland.

(Honestly, this sort of thing is the reason that I'm rather critical of Ubuntu: I've never had a "mainstream" distro issue as many breaking updates as Ubuntu does.)

I've been noticing this as well. As good as Ubuntu is, I'm afraid to update anything. I may just reinstall, and only install security updates. At least it only takes a little less than an hour for me to get all set up again.

Well, I found a solution, at least for now. From the standard USA repo theres a program called "StartUp-Manager". It's just a simple GUI interface for editing the GRUB boot loader. Anyway, Ubuntu keeps the last version of the kernel as well as the most recently updated. I simply selected the boot with the old kernel, now everything works as it should. I'm not sure how this will be effected with future kernel updates (hopefully this problem is fixed by then) but, for now it works just fine.

Thanks for all the help.

Well you might have a bit of a problem if your current kernel turns out to have security holes... but I guess for now it's a workaround.
