Summary: It appears to me that the laptop is shutting off before the suspend processes complete, and then it completes the suspend processes after resuming and consequently becomes confused and crashes. Is my interpretation of the log correct? How do I solve this problem?
~~~
Pressing the power button to resume from suspend, the screen remains blank. It does not appear "to resume correctly but leave the screen turned off" because pressing the power button once after this failed resume turns off the computer, whereas in a normal session pressing the power button once has no effect.
This Sept. 2012 answer did not solve my problem. Here is the output to confirm that I changed the setting (the problem occurs whether false or true):
user@computer:~$ gsettings get org.gnome.desktop.lockdown disable-lock-screen
false
user@computer:~$ gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'
user@computer:~$ gsettings get org.gnome.desktop.lockdown disable-lock-screen
true
Is there some particular info from the output of the list hardware package lshw that I should share here? Here is some info I saw about the display:

Following the instruction of a comment to this May 2011 question, here is an excerpt from /var/log/kern.log. Corresponding actions that generated this log:
- 9:40 suspend laptop
- 9:43 pressed the power button to resume
- 9:43 waited a moment to verify the screen remained blank
- 9:4? pressed the power button again to turn off the device
- 9:4? waited a few seconds then pressed the power button again to start up.
It appears to me that the laptop is shutting off before the suspend processes complete, and then it completes the suspend processes after resuming and consequently becomes confused and crashes. Is my interpretation of the log correct? How do I solve this problem?
It may also be noteworthy that I apparently do not have a /var/log/pm-suspend.log file.
