[Carbon RC2] screen lock bug

I installed prior to RC2 but I assume that as long as I have been keeping everything up-to-date that it is equivalent to RC2.  In any case, on an old Dell Latitude E6530, I'm getting the following error/warning.

Re: [Carbon RC2] screen lock bug

^The image didn't display but I found the post BB code was a bit off and edited it.

What did you do to attempt to lock the screen? I'll try to reproduce the error here.

It's difficult to emulate this on a VM because 'systemctl suspend' just makes the screen go black, with no way out except rebooting.

I plan to install RC3 onto bare metal soon, so I'll see if I can reproduce the issue.

Screenlocking itself seems to work OK on a VM though.

Has anyone else had suspend/locking issues with the Carbon isos?

Re: [Carbon RC2] screen lock bug

On the system settings for the power manager, I ticked the box "Lock screen when system is going to sleep".  The laptop has no problem suspending.  The problem is that when I come out of suspend, it gives the message (the screenshot/error-window I posted) "None of the screen lock tools ran successfully, the screen will not be locked. Do you still want to continue to suspend the system?"  The answer of course is "no" because it just came out of suspend.

Tested on my laptop which is an oldish hp255 G4.  Worked as it should no messages.

Re: [Carbon RC2] screen lock bug

Ok, it seems to happen when the Power Manager times out.  It is set to suspend after 15 minutes idle.  It came back up successfully screen locked but with the above error message.  But when suspend gets activated by shutting the lid, all goes according to plan.  The system gets suspended and the screen lock is activated.
