thinkpad t520: suspend by closing lid works, opening lid un-suspends and then suspends again.
Last modified: 2013-01-30 07:51:18 EST
Description of problem:
Suspending the laptop by closing the lid works just fine.
Un-suspending by opening the lid (usually, not 100%) un-suspends, and then immediately suspends again.
Symptoms are the same as this older bug from Fedora 16:
Version-Release number of selected component (if applicable):
Thinkpad T520 with BIOS version 8AET60WW (1.40 ) (fairly recent as of this writing)
I was using Fedora 17 previously, and did not experience the double-suspend.

/var/log/messages during a double suspend/resume cycle
Fedora 18 running vanilla 3.7.5 on Lenovo Thinkpad X1 Carbon. Same thing happens with fedora kernels.
This is /var/log/messages between such a cycle. I closed the lid, it suspended, I opened up the lid, it woke up a bit (saw console again, no X) and then immediately suspended again, I then pressed the power button to wake it up again, it woke up and everything works fine.

/var/log/messages during a suspend/resume cycle FAILED CASE
When in X I closed the lid and reopened only to witness the system suspend again. Lid closed and reopened and then it gets back up.

/var/log/messages during a suspend/resume cycle OK CASE
And about one in five or so it works as expected.

/var/log/messages during a suspend/resume cycle OK CASE when in tty2
And when in some other tty it works every time.

/var/log/messages during a suspend/resume cycle OK CASE suspended from kde menu
And if I do the same thing from the KDE menu it also works every time.
Bug 859227 deals with this. Upgrading kde-workspace to a newer version (currently in testing) seems to fix this (with some minor side effects).
