Freeze on screensaver deactivate when set to lock on screensaver activate

[Carl Miller]

A few months ago, I started having a problem where my laptop would freeze and require a hard reboot when I tried to wake it from screensaver. I tried turning light-locker off; this fixed the problem. However, now due to company policy, I have to turn light-locker back on, and found that the problem still existed. After some searching, and trying different things, I've found that if I set light-locker to activate on screensaver *deactivate*, then everything works properly, and when I wake the laptop from screensaver, I'm presented with a blank X background and password dialog. If I set light-locker back to activate on screensaver *activate*, then my computer continues to run until I press a key or touch the touchpad, at which point it freezes.

Note, I keep suspend and hibernate turned off completely on this laptop, and almost never run on battery. The above happens when plugged into AC power. It would appear to be purely in the realm of light-locker and the screensaver.

Carl Miller, as per http://us.msi.com/support/nb/GT70-Dominator-GTX-970M.html#down-bios&Win8.1%2064 an update to your computer's buggy and outdated BIOS is available (71D). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Hi, Christopher. Thanks for all the helpful links! Indeed, I applied the BIOS update, and the hard freeze is now gone! It's not all working exactly as I expect, but at least the BIOS change cured the worst symptom.

Changes made:
Applied MSI BIOS update to version 71D.
Changed light-locker back to activate on screensaver activate.

New behavior when coming back to laptop with locked screen:
Make a movement on the touchpad. Screen remains completely black, BUT computer is still running properly, as shown by network traffic.
Click the mouse buttons. Same thing, screen remains completely black, but no hard crash; everything is still running.
Press some non-typing keys (shift, ctrl, etc.). Same thing.
Blindly type my password into the completely black screen. Screen turns on, unlocks, and shows me my full working X environment, exactly as I'd left it.

Which is at least usable. Not ideal, and not what I think is expected behavior, but behavior I can deal with.

chaz@cesium:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
